King of all motors?

[CALVIN]

Which motor would qualify for the title( KING OF ALL MOTORS). Classes might include , most years produced, most motors produced,or most reliable or fast!

[1BadAction]

this is my vote. not because of weight, not because of reliability, but because it is downright badass.

thanks to raceman for the perfect example of an f1 V8.

That V-8 is pretty cool without a doubt... In my opinion the king of all performance engines is the 260 merc , they have been everywhere and done it all - Fishing rigs , drags , offshore , ski rigs etc... Lightweight , high revving , strong power , parts availability and all on pump gas... I can't wait to see all the responses that are ready to roll in..

[mendo]

That Johnson Rotary is just wierd enough to be cool and they were quick in thier day!!!!!

[CALVIN]

Was the f-1 driver Barry Woods the first to try fuel injection on the f-1 tour? How many different f/i units were there?

[rmh77]

King of all boat anchors!;)

[Raceman]

Calvin, the first injected F1 type outboard I ever saw was the Merc stuff with the old mechanical Bendix. The factory boats had em, but I don't know who was first. I'm guessing maybe Seebold, but Reggie and Earl may have had em at the same time. Back then the factories used a lot of tents and tarps when they had the Team boats at the races. I do have a picture from 1978 of an OMC CCC at St. Louis with a Bendix injector, but I don't recall the number on the boat and think Merc had been running em a couple of years by then. There are also rumors that some of the 6 carb inline powerheads had some form of injector, but I never saw one back then, so I don't know.

I never saw any of the top V4 OMC stuff with anything other than the 8 barrel carbs, so my GUESS is that they were a couple of years into the CCC/RS program before they went Bendix, but it's just a guess based on chatter at the races back then and a shakey memory as to exact year.

2.5 260!!!!!!!!!!!!!!!!!!!!! What eles is there?????????????

:D :D :D :D

2.5 260 MERCURY.IN MY OPINION THE BEST THERE IS!

[DarthVMAX]

Refers to the TOP position....this place is called SCREAM & FLY which is referring to SPEED! Most everyone here whether they have 2, 3, 4, 6, or 8 cylinders is always trying to go faster. So I would say SPEED is the predominant theme here. The F-1 V-8 is THE FASTEST OUTBOARD in HISTORY......PERIOD!!! That is a FACT, which is non-debatable:D

Long live the (V-8) KING!!!!:cool: :p

my point exactly, an f1 v8, the wickedest outboard ever!

[steve]

The F1 OMC would be the top dog. I think most of the Merc 260, 300 drag guys have never seen one run. In an 800 ft track, I have seen an F1 beat by 2-3 boats off the line and by 400ft be dead even and at 800 ft be 2-3 boats ahead. Very impressive indeed. This was a heads up drag race and no weight or motor restrictions except no NO2 or turbos etc. Plus they were pretty light for a big dog. :D

[beer30]

If making a engine go fast make it king, then the Merc. 2.5, is king by a mile. But straight stock from the factory, there is a few to chose from. My choice is the T2X.Chuck.

[Chummy]

I gotta ask because I don't know. Why does the lower throttle body have spacers and the top not have any?

[steve]

The F1 was around 450hp powerhead as I recall. No contest . Even a full mod ProGas 2.5 Merc would not keep up with one. Merc 2.5's are my favorite but they are not the King of Motors. IMO.:rolleyes:

[Hot Shot Merc]

At the Race Rock cafe in Orlando ther is the world record speed holder for an outboard powerd boat haning from the ceiling.It ran over 170 mph ?I think and it has one of those big omc beast's on it with no skeg on the gearcase.It runs a tiller to stear it.That motor looks exactly like it.Also the fastest drag boat I ever saw was Jack Barsh with an omc v-8.I dont think it makes the the king but they sure do get the speed job done.As far as production numbers,life span,reliability and allaround power and popularity.MERC-HIGH PERF ANYTHING.

[V8astrovan]

ya the fastest outboard ive seen is my buddi paul wheeler he ran [email protected] w/ a mod 2.5 s3000 powerhead. his motor is bolted rite 2 tha transom w/ a tiller for stearing. its a hydor like the 1 @ hrad rock.

[Ted Stryker]

The F1 omc was fast sure , but the "King Of All Motors" should be jugded by more than just HP... The 260 merc has been everywhere and done it all... Numbers of engines produced , parts availability , performance , weight compatibility for a broad selection of hulls so on and so forth... I would like nothing more than to have the money to fab one of those F1 V-8's onto the back of my XR Allison , but unlike the Merc - the big Evinrude is impractical in a lot of situations... I'm a die hard boat nut , and that means I still like the V-8 just alot of times it don't really fit... I believe that's a valid factor... OK I'm ready to me mauled now!:)

[V8astrovan]

i agree w/ ted the 260 is the best motor all a round soooo i think it should b the king of motors if not it then the 280 should

[zmoz]

I'm gonna have to say the Mercury inline 6, for reliability. (and speed in it's day) Mine went 6000 RPMs for 10 minutes without oil, seized up, and STILL ran fine the rest of the day. Only died because the timing belt somehow got chewed up. Pretty much any inline 6 motor is known for it's reliability.
http://zmoz.us/wakesmall.jpg
You gotta admit it's pretty damn sexy too. :D

[Hydrovector]

the motor picture you posted is not a 260 but a 300 drag. Jim Summers old drag 300 is in the picture. Picture taken at Aquaholics. But is a cool motor.
But my vote would be the F1- V8.

[spanky2002]

ONE FACTOR THAT HAS NOT BEEN BROUGHT UP IS THE HORSE POWER TO CUBIC INCH OR CYLINDER RATIO. MERCS HP TO WEIGH RATIO IN A FULL PROGAS MOTOR IS ABOUT 62 HORSE PER CYLINDER. THE F1 V8'S RATIO IS 56 HP PER CYLINDER.

that doesnt matter when there is no displacement limit. if you want to go that route, this is the king of hp/liter

[steve]

Man thats awesome. ProGas is making 372 hp ? Last I heard was around 350 powerhead . I thought that was pretty good. Remember the F1 was a carb rated motor at around 450 and we are talking unmodified also. Plus the thing weighs very little more then a 2.5. Man would I like to have one to play with! ;)

steve, i visited a certain FL engine builder, and looking at his book of dyno sheets, most of his 2.5 lake motors were more than 350 hp at the prop. the one i looked closely at was making 270 at 1700 rpm, peaked 355hp @ 8000, and was still making 280+ hp at 9000 :eek:

[steve]

If you are talking about a prop style dyno then I'm not impressed. If you are talking a stand alone powerhead dyno then I am. Seems alot of the prop style are good for comparisons if you do mods etc but I would not count on the hp readings from my experience. Was it Dean Pinks or Diamonds shop? :p

[1BadAction]

steve, your PM box is full :p - it was a stand alone ;)

[BarryStrawn]

Are you sure about that 270hp @ 1,700rpm?

[Doubledog]

Im in........... BRIDGEPORT !

[V8astrovan]

yes i kno that is a 300 drag.... it still still queen of motors 2 me cuz the 260 or 280 is king,but evey1 has there own opinion on what motor is king...... sum ppl like merc's sum ppl like omc's...... sum ppl go by hp sum ppl go by reliablity.... sum ppl goo for big ci low rmp's sum ppl go w/ small ci high rpm's...... sooo either there is always a motor better then the king n sum way...... cuz while that big v8 f1 is blown up afta runnin down the river for 80 miles the 260 is still going..... or even the 300 drag is still goin

[DarthVMAX]

What is KING? Around here...SPEED! Look how many threads are about whos gonna smoke whos azz! Then look how many threads are about "Brand X gets way better fuel mileage":rolleyes: or "Brand X is more dependable":rolleyes:
or "listen to how quiet brand X is" :rolleyes: GIMME A BREAK!!!:D

If a black motor had the speed record we know alot of tunes would be sung differently:D

F1 V-8:D :)

[Ted Stryker]

The merc is fully capable of the speed record... There has been a certain drag hydro powered by merc that has gone 155 mph plus in the 1/4 mile , yes the quarter mile... Thats averages out to an acceleration of about 20 mph per second.. Propped right and given a little more room another 20 would not be a problem... Zero to 150+ in seven sumpin' seconds pretty damn much means that the standing speed record is easily breakable from a power standpoint...Whadda you really think?.. Just to clarify , is this topic about the most factory HP or overall superior engines... Enquiring minds want to know...?

[Airboater]

1/4 mile and kilo runs are completely different .The merc would have to enter the trap at the record speed and hold it for the length of the trap and then make a return pass withen 30min to back up the posted speed to get a average of the runs.Question is can the merc stay together for two passes at those rpms:eek: .The run the F1 V8 made was useing a backup prop since their best one was damaged in a earlier test run which they claim 200 could have been reached.

[Ted Stryker]

I understand what your your saying , but if 150+ in 1320' doesn't show capability to spare then I'm confused... Think about the shortblock stresses that the merc had to harness to facilitate that level of acceleration... Much more than a 175 mph holding speed......... In my opinion..:)

[RRRevinrude]

with airboater--acceleration and sustained mph are two totaly different things....if it were that easy-mercury would have done it years ago....

[Freddie Webb]

I am not sure where all of these numbers are coming from but, the omc v-8 has the 1/4 mile record that was tied by Jon Wright with a Merc. The top speed is undisputed by omc at 176.55 two way average. The record is very possible for a Merc but it would have to turn a 23 pitch on a iv gearcase 10,200 with 10% slip for 5/8 of a mile and turn around and do it again that would tie the 176. In order to break it Merc would have to turn a 23 pitch on a vi gearcase 10,200 with 10% slip for 186mph. I think it is possible but many have died trying are you up for it? I hope you have Jesus in your heart.

[Ted Stryker]

As for the sustained mph comment... I ask you , how many OMC's do you see as a threat in Offshore racing?

[V8astrovan]

hey for real im gonna agree w/ ted

[RRRevinrude]

ya'll don't consider omc as a threat in any kind of racing...BUT for now they still hold several records that haven't been broken even though the technology has improved a whole bunch since omc got out of the racing business............

[1BadAction]

no sub for CID... simple as that, no matter what you do to a 2.5L you can do it to a V8 and make more power... 4.0 Liter! :eek: thats a 150HP advantage in displacement over a 2.5

[Ted Stryker]

Hey 1BadStream , Your post about cubic inches is true considering if all things are equal -guess what all things aren't equal.. Horsepower is created by efficiently burning a given amount of fuel in a given frame of time.. More things come into play other than cubes , like airflow AND RPM - the two are closely related... Although exagerated , heres an example... Harley verses Jap inline four... Grandpa's crapbox has more cubes and burns lots of fuel , and the saltflat records between the two of them are probably comparable... I'll go ahead and quit on that one... How about a 2.5 Merc block w/2.4 sleeves (142 ci ) will stomp the **** out of a unmolested 2.4 (142 ci ) Merc...? Airflow between the two castings is different... Cubes help but there not everything.... To RRRevinrude , an M3 BMW will outrun 60's era 450 hp muscle cars across the board... Which one hold more records , and has more of Uncle Buster's folklore behind it.. It's not the Beemer , but that isn't the whole story now is it... An F-15 still holds the vertical climb rate record , but to the folks in the current and know , that old record is null and void... A written record doesn't necessarily prove who's the best , just the most recognized...;)

[V8astrovan]

damn ted u took it rite outta my mouth... lol... it seems like we agree on alotta things..

[Ted Stryker]

The outboard top speed record is the ONLY place that Mercury hasn't actually , physically gone out and proved it's dominance... The OMC guys are holding on to that one last island in the stream in a last effort of glory... In regards to the record in question , I believe the credit and glory mostly belongs to the driver and set-up crew rather than the engine manufacturer....:cool:

[Freddie Webb]

The v-8 that set the record was a 3.6 liter to the best of my knowledge totally different from the production motor. Ted, what's the fastest Merc that you know of? The fastest I've ever heard of is 167 from someone I believe. That is a long way from 176 but I will agee with you that Merc has the capability. But I will also say that record was set Dec. 1989 and those v-8 motors have much more potential.

[Rodney Nance]

The best way to go in trying to reset the outboard speed record is with cubic inches. A 4 stroke with a turbo or supercharger would be the most practical way of doing it. Freddie correct me if I am wrong but you said Jon Wright tied the OMC 1/4 mile record. Jon ran 7.52/156 and the IHBA certified it as the worlds quickest and fastest pass ever with a outboard. Am I missing something?

[Dd24skater]

Are there any parts out there for those big v-8's

What do you thing one of those engines are worth?

[Raceman]

The parts are rare as are the motors. It's hard to say exactly what the motors are worth, with so few of em around and the fact that they almost never change hands. I bought mine from the original owner who'd long since quit boat racing. The problem was, some of the components had gotten seperated with the motor having been moved around several times. I'm still missing a few key pieces.

[Freddie Webb]

My apologies to Rodney and Jon for not having my facts together. I am man enough to admit when I am wrong.

[Dd24skater]

Hey Raceman

You seem to know about those engines,

Were they around 425 hp and what kind of fuel did they use.

Didn't they make an offshore version and was it 20 or 25 inch

Did the gearcases have a twin pinion set up?

Thanks for the information

Dd

[Rodney Nance]

There is not a one of us that posts here regular that has not made a mistake before.

[Raceman]

Dd24, actually I'm not real knowledgeable on these engines even though I own the one in the pics. The horsepower issue is about as volatile around here as discussing tuners, HydroStream hooks, or Amsoil. Personally, I've always doubted the ultra high horsepower estimates that some people have made for these engines, based on the fact that the 2.4 liter Mercs of that era that undoubtedly developed horsepower in the upper 200's AT BEST were able to stay somewhat in the race with them, especially on tighter courses with slightly smaller boats. That's not to say for one minute that the V8's didn't have more power than the smaller Mercs back then, but there were some cases where the Mercs were even able to race successfully against em with some double teaming by the drivers and other circumstances on shorter courses. I've never thought that this was indicative of almost double the horsepower, but that's just an opinion. In any case, and regardless of who you believe on horsepower estimates, the F1 V8 was an impressive engine and a formidable competitor at any level. It's a shame the program was pulled most likely long before it reached it's peak. The same can be said, probably to a greater degree for the 3.4 liter Merc race engine which was also killed way prematurely. It'd be interesting to see where the programs would be now had either engine been given the opportunity to evolve to the level of the present 300 drag Merc 2.5.

Back to the question, again I'm no OMC expert, but if they made a 20 or 25" version of the F1 injected V8 for offshore use I'm unaware of it.

[1BadAction]

everyone know this is actually king of all motors :eek: :eek: :D

[Techno]

Your all wrong. OMC and mercs are junk. Its those engines after the engine builders and back yard hackers and sperimenter get done with them that are king.

How many of those engines youse speaks of is unmodified?
How many races has mercury or omc won? Not sure myself but I think its none.
It was the dude who bought the engine and the boat and then played with those parts that has the record. Whos money and sweat was it that got those records?
How many parts are sitting on a merc now not from mercury R&D but isolated racers and funtimers that found a better way and now finds it on the production OB?

How about the Brucatto induction on the production merc? Who came up with that idea?

Just look at the aftermarket parts available and wonder why they aren't on a merc from the get go instead of afterwards.
Some of these parts have nothing to do with warrantee so thats not the whole picure. Neither is merc having to build for many needs- what need does a 260 fill? Or a drag? Kind of a narrow field for those 2 engines. A 280 is a good engine but lacks the 260s electronics, why? Shouldn't there be a 290 or whatever it would be?

No the king of the hill motor is the ones those guys modified.

If your talking strict stock then it doesn't exist. The companies tried to spread the field too much on thier stable of same engines that spread the ease, life, hp, warrantee issues. A 2.5 is a 2.5 in how many choices?:p

While the F1 V8 causes a stirring in my gut (sure is pretty, Raceman!!! ) , my vote goes for the lowly bone stock OMC 115 hp v4 crossflow, it's got yank your ass out torque, you can't kill it even with disel fuel, you turn the key and go from day one till you sell it cause you want to go faster and a year later wish you still you had it cause your new go fast is broke in the garage and you just KNOW the 115 you sold is still gulping gas ans rollin' down the river.............

The box under the scoop contains an intercooler.

Here's the installation,

[Flat Out]

has to be the OMC racing V8. They could still kick a** today. Too bad they killed the program.

My second choice has to be the Johnson/Evinrude 18 hp of the late 50's thru 70's you just can't kill them. How many RPM's when you break a shear pin at full throttle ? You can overheat them to the point where you can boil water on them, let them cool down and your back on the water. They made a gazillon of them and parts are everywhere and dirt cheap.
You could sink them and have them running in 5 min. try that with a new motor forget about a four stroke.
Not the fastest or the most glamorous but day in and day out they run and run.

[Ted Stryker]

That's what I like about the turbo theory... As long as your turning enough RPM'S to be on the pipe , the only limitation is your shortblock--- A real perpetual energy maker.... I've seen some 4 and 6 cylinder cars on the street cream some hairy forearmed big-blocks, with alot less noise and better fuel mileage... One of my favorite things about them is they're only there if you need them , like the perfect hitman that keeps to himself... I was at the Fun Ford Weekend in Ennis,TX. year or so ago... 306 C.I. turbo small blocks keeping 600+ inch mountain motors from getting too cocky... They've definitely gotten the turbo lag thing solved , those small v-8's were shoving 1.1-1.2 60' times... The performance they had in the upper gears were eery and gave me chill bumps to watch... In my soul, I'm a boat guy but I love turbo v-8's... I may see a new hobby for me awakening...:cool:

[Unchained]

Ted Stryker,

The turbo setups are especially good in a boat because you have all the lake water available for an air / water intercooler and you can generally run the engine at a cooler temp to resist detonation.
I've been pretty successful at running 14 lbs boost on pump gas 93 octane.
With my setup the turbo's are just inexpensive diesel rebuilds.
I had way more money into the blower I ran previously.
I had to swear off the roots blowers as an inefficient crankshaft horsepower subtractor.

yeah, single turbo kits for LS1 that will put a 5.7L into the 10s on street tires and pump gas... 700+ hp daily drivers with nothing but the turbo mods, and some LS1s with special cams that make 1000+ hp on 100 octane, but are still daily drivers :eek:

unchained- i have always wanted to do a de-stroked 350 with GM performance nascar heads, and a twin turbo setup on a 3 point hydro- you think an aluminum block could handle something like that? (6 bolt mains are standard)

[Ted Stryker]

10-4 on the roots type inefficiencies... I estimate a 20# of boost it takes about 75 hp at the very most to spin your turbos , as compared to 3X that for a roots or centrifical units.... And the fact that there driven by the "laboring" of the engine as opposed to pulley speed is a dream come true....

[Steve Reist]

Thumper, I owned a 76 model 115 and was
just what you said! I wish I had it back for
my jon boat. Steve

[Mark75H]

Please explain this:


20# of boost it takes about 75 hp at the very most to spin your turbos

I always thought a turbo ran on exhaust gases that were normally not put to use; effectively getting power without consuming any from the crank and in effect actually gaining power due to increased efficiency? ie. 50% more power could come from as little as 20% more fuel? vs a decrease in efficiency with a gear, belt or shaft driven blower where 50% more power would come from 100% more fuel

[Ted Stryker]

Your right but I think you've overlooked something...Turbo's are a bit of and exhaust flow hinderence.. Your exhaust pressure is having to accelerate the weight of the turbo's internals just to escape your engine.. While doing this they return an intake charge back into your engine making a profit so to speak , but they're not entirely free power just at a lesser cost than other forms of forced induction... I guess what I mean is if Unchained' engine was recieving the same amount of forced cfm from a remote supplier (other than his own exhaust) and given the fact that his engine had completely free flowing exhaust(turbo free) his engine would make more power than it does now... I estimated somewhere between 50-100 hp , but I'm no Will Hunting...:)

[Mark75H]

Nope, if more power was created from less fuel, the turbo is not sucking power from the engine in any way like a shaft/belt/gear driven blower.

Your independent/separate blower scheme would give more power than the turbo, but not if you include the power source running the independent blower.

[Ted Stryker]

Mark75H , in regards to my last comparative scenario-It's kinda like this.. How much more spendable cash would you have if someone else was paying your bills.. Your spendable cash amount would not be affected by what your supplier was having to spend.... Your last post seems invalid to what I was trying to say so I don't know if were on the same page, or taking different paths to same answer..I know turbo engines ultimately produce more HP , but internal conbustion engines can't be 100% efficient just some more efficient than others... The amount less than 100% is sum of what the engine is spending in overhead cost , no pun intended... A blower is doing the same exact thing as a turbo , but their "drive" origins are different.. One power supply is more efficient than the other but not free... Turbo lag in some mis-tuned set ups can demostrate this, when the turbo isn't putting out quite what it's taking from the engine yet in the rpm... Kinda at a point when the turbo is just parasitic before it returns the favor...

King of motors for longest production run:

Merc 44 cubic inch 4 cylinder:

First produced as the "Mark 58" in 1958

Ran thru the 60's, 70's & 80's as the "Merc 500"

Produced thru the 1990's as the "Classic 45" I don't know what the last year was, but basically a 40 year production run.

Probably leads all motors in over all number produced, too

If you include its 40 cubic inch ancestors with the same crankshaft and very similar layout you go back another 8 years and start in 1950 (50 years?)

Are my most liked motors. But Sam is rite, the 44 motor is a real nice small motor. It's been around forever.:cool:

HERES MY CHOICE

[Laker]

The most ultimate in outboards and the effort put forth was the V8 F1 motors. From the start to the end they were and are the best!
I do have to agree with Thumper that the V4s are all they are cracked up to be and more

oops
I Ment the 115
HEHE:D

My contrarian vote goes to the current 225 HO Rude.

Big power, big acceleration. Big weight limits use on smaller boats. Runs regular gas and has oil injection. Easy. I bet its much more reliable than the big power Mercs.
