3.0 Litre Potential????

[beer30]

After seeing Dez Nuts do 135 in his STV with a modified 2.5; It got me to start thinking about how fast some one has went with a 3.0 ( 300 PM, 300X, or a modified regular 3.0). I know my Q-shot has more in it, but to turn the REAL BIG #'s it would have to turn at least 7500 rpm's. That a bit over the limiter. Has anybody else seen BIG #'s from these engines? I am thinking 125 plus. :) Chuck

[SUPAJAY]

Thats a big no no. The 300x motors were blowing up because people were stringing em out to 6800... at 7500?? i dont think anyones done that before, i wouldnt do it. :confused:

But hey, if you got the dough to take the chance... why not ? :D

[Euroski]

I think I read in last year that MADEFI had a 300PM turning almost 9000 with mods.

[Scream And Fly]

Chuck, I think your boat could run 125 with the right prop. You're very close to it as it is. And the 300X is very cool!

[WILDMAN]

Lake Trash is turning his Mad EFI 3.4 litre at 8600. He said he's been smokin the modified drag 300 guys in 700ft drags. He said"by alot!" He told me he's been making over 30 passes a day with no problem. Madman [Wayne Taylor]told me that he does'nt recommend turning them that hard though.

The power range of the engine peaks at 6800 to 6900!!!;) Who has blow up going that fast?:confused:

Greg- I think the prop is definitely an issue that I will address when the weather breaks. Last time out this past season the weather was perfect, but I was the ONLY boat on the river. Didn't want to push it too hard, in case something was to go wrong, and not have any help. Chuck

don't believe everything dennis tells you. the boat's only been ran at one of our rally's. 30 min after i got there i pulled of the beach and tried to line up with him. when he saw me he pulled off to race somebody else. i ended up racing a jet boat and had some handling problems so i called it a day. we did both race the same jet and i do think he may have done a little better against the jet then i did. i pretty much tied with it and he got it by a 1/2 of boat or so. i was running 1/4 mile set up cuz i was testing some things for a DSRA race the next weekend and will admit it would have been a very close race, but with it's limited rpm range i think he'll have trouble with a 2.5 if it's geared and propped for 600'

but don't get me wrong the boat hauls the mail, it just ain't smoking the 2.5 guys at our rally's, but for top end i'm sure it will through down some big numbers

What is why?? Because he used Simon? Because he only had 335hp? Because it wasn't 335hp?? What???

[WILDMAN]

I talked to Herb a while back. His red boat ran 107 with the 300x. He said he sold his boat to a guy who put a Simon motor on it. It now runs 96mph. I'm sure Herb helped setup the new motor on it for the new owner.

[Tony Montana]

11mph drop? Gotta be simon's fault, what else could possibly effect speed when there is a motor change and a new owner of a boat? :D

[stylishskier]

I believe I remember the new owner saying 100+ would have been easy with a prop change, he was running 96 or 98 with a 28... dont quote me but he said 100 was well within reach with some setup work...

[beer30]

Also Ray did not have a 15" mid, or the experience driving the boat that Herb had. :) Chuck

[msg11]

Beer 30
I blew my 300X up, it was not do to high RPM'S, it was bad gas. The potential of the big blocks are limited, the rods are small,hugh internal weights,300X PCM. I feel if we do anything,try to make parts better on the inside, first top pin the pistons,weigh they the same ,teflon or kryo treat them, do all the same things you would a race motor. If someone can change the fuel curve and raise the rev limiter,we my see the potenial of the motor, but, then we would have a race motor with no life, and or longivity. If propellor manufacturers made a 36 pitch, (that was affordable)we could do the same thing on top end, with lower RPM. Then we take the chance of prop breakage. I am sure that all I have said has been thought of already.

[RBT]

To build a mod motor 3.0 ( or bigger ) would not be hard. All you need is a checkbook, as the resources are there.

- Billet CNC Crank from Dave at Marine Crankshaft
- Billet CNC cracked cap H-Beam rods from Dave Cunningham
- ART pistons... uncle ER can help there

While we have ER's help, might as well stroke it a little as at this point you can do ANYTHING.
Get a competent guy to port it and you should be in the 450hp range at the flywheel. ( for reference the 2.5 is at 400hp in full race trim at the flywheel ).
You would have to run a real ignition system like Motec or BigStuff3, and get Tony to build another of those crankcase injected SVS's.... but it can be done.
It is just a matter of a doner block and about 15k...... LOL

That was going to be my question. A better or clearer answer would have been to have the simon powerhead bolted to herb's setup and let herb drive it.

Herb went 107 ro so, doesn't mean everyone else on scream and fly could jump in that seat and do it.

Back on topic. Anything can be done, $$$ is the question.

Isn't the 300X block beefier then the reg. 3.0 block? Chuck

[SUPAJAY]

I bellieve the 300x block has different porting.

[SUPAJAY]

What is why?? Because he used Simon? Because he only had 335hp? Because it wasn't 335hp?? What???

Herb set up the red boat with the simon 335. Still couldnt get it past 96mph. A 300x being a true 300 at the prop and maby 330 at the crank, Pushed that boat to 107. Maby the 335 really isint 335 :confused:

And i seen herb at Tanner setting the boat up with that motor. With all his experience it defantly wasent driver or setup error.

[RBT]

Yike,

The 300X is more like 320 at the prop.......

I am curious, not trying to stir it up at all. But I do not see on the Simon websight any mention of porting. It to me seems like all bolt on's to any 3.0 block. If that is the case, I cannot see it approaching the X motor.... but I would beleive 335 at the flywheel.

RT.... and 11mph is A LOT on the same boat with the same driver.

[SUPAJAY]

Agreed. 11mph is alot. I dont know about 320 hp at the prop with the X tho...? Any dyno sheets on a stock X ?

[RBT]

"Any dyno sheets?"....... yup but I cannot post them........or I never will get more. But yup, all of 320hp at the propshaft.

RT

[msg11]

Told that the 300X has a higher port timing than the 225 3.0. I had both the guys from Hydromotive enginering in my boat at the Rumble on the River once and was flat out with 4 people and a cooler full of beer. I was running one of there props they worked for me, we were turning 7000,the smart craft was flashing and buzzer going off, I switched the gauge to fuel consumption window,and it read 32.9. He said that related to the horsepower the engine was putting out,and we were running at 105 on the GPS.:D

[beer30]

I guess my only option is to work on props. A 36" prop turning 6800 would run about 130 with 10% slip. A 34" would need to run 6800 with 5% to get close to that. That's what we will concentrate on before touching the engine
with any mods.:) Chuck

[03bignasty]

I read this post and wasn't going to comment but that is absolutely crazy. Something was definitely not right with your friends motor. I have the simon motor on my stroker and the boat will consistently run 103mph in the cool weather. The boat has run 103.3 on 3 occassions. An x on the same boat runs between 103-104. That speed was witnessed by many of the guys on this board on lake Jackson. Bobby, yellow Merc. ran 103 with Eric's motor on his 20 foot bullet and 104 with his 300x. I don't know about dyno sheets or any of that stuff. I do know that the motors will run with an x and will outrun an xs easily. I also know that Eric's customer service is second to none. I have never had a problem that he hasn't fixed asap. Motors are mechanical and mechanical things can break. Look at the x's and xs's on this board that have blown. Does that mean that they are bad motors absolutely not. Eric's motor run pretty good. Check out the gpshttp://i36.photobucket.com/albums/e20/03bignasty/P1020386.jpg

[ASPB]

The power band on the simon and the 300x are different therefore you will get different speeds with the same prop.you have got to prop the simon mota right and if you do it might be 1mph slower than the 300x.i have seen and ran against a few simon 335's run and they are the juice.I think the power band is simular to that of the 300xs.And simon's warranty is second to none.if your's isn't running right it's because it may not be set up right.we are running them on 1200-1400lbs bassboats.i just had a bud do the simon mods to his 300pm and he has it on the back of a 21 blazer.After the mods he picked up close to 4mph.

Simons motors are exactly what he sells them as. 335hp. If anything the majority are probably over that. On my boat I gained 7mph over stock 300pm's. Same setup same props same everything except the motors.

A 300x is a true 300hp motor. Therefore, the Simon 335 should drastically outperform it. Comparing apples to apples. There shouldnt be a comparison, 35 more horse in an outboard is plenty to show a difference.

Skatin - Its obvious that the simon mods helped your talon. Anyone running the same setup with twin 300x' ?

Herbs boat was a perfect example to show how the two motors perform against each other.

Just my .o2

Thanks,

[ASPB]

Put a simon and a 300x on the same hull and it may come down to set up and the driver.There may be 10hp difference at best between the two.The 300x and simon mota are both bad boys.

[beer30]

A test comparison between the 300X and the Simon 335 would be very interesting. You got people who are very impressed with the Simon piece (Hogg, Skatin to name a few), then you have people who see it a different way( not as good as a 300X).
There is definitely not as much mods on the market for the 3.0 as the 2.5. a big dis-advantage for getting every ounce of power out of it.:) Chuck

A 300x is a true 300hp motor. Therefore, the Simon 335 should drastically outperform it. Comparing apples to apples. There shouldnt be a comparison, 35 more horse in an outboard is plenty to show a difference. Are these both crankshaft numbers or propshaft numbers or do we have some oranges?



Herbs boat was a perfect example to show how the two motors perform against each other.

Not exactly, one was a 15" mid, one was a 20". Could affect the handling, or maybe it didn't.

Different drivers, I am sure that makes a big difference on that particular boat at those speeds.

Same props?

Too many variables. Now if you told me herb blew his x, picked up a simon powerhead and ran slower then I would say you have a point.

i also heard ray was having trouble with his engine at that
time, and it turned out that he had a cracked chamber in
one of the heads.

thats what im trying to say.. lets just change powerheads and see! ive got one right here in sunny florida if someones got an x motor they'd like to put up and we can see.

[ASPB]

The thing is,if you run the same prop on the simon as you do the x the simon will be slower because of the power band of the simon.Usually you have to run a bigger prop.

i talked to eric about doing a 3.0. he just cleans up the

pistons are oversize i think so it makes a 3.1 i think.

Herb setup the boat with the simon and tried numerous props. Im sure that includes the prop that brought the boat to 107 with the X. The difference between a 20 and a 15'' would not be 11mph.

Ok guys I just read this post I have to sick up for simon here I was helping with the set up and Ray had some issues, which simon repaired. Than ray didn't have a good gear case either, I told Ray what he needed to buy, for starters he needed to get side mount sterring the front mount had to much play and you couldn't drive it, so he got that, than I told him to get a gear case with the right gears and so on. By the conn river run he had everything he needed but the prop so I brought mine along to put that big number up with me driving except agan he had a problem with the mtr. As far as I know he sent the motor back agan to be gone though and put the new intake that simon has made on it. But i think Ray has deceided to buy a House, so he put the motor up for sale, if it does'nt sell it by next year we will get to see what the simon mtr has to offer.

The motor is at Simons place right now. I'm having the new intake put on and having everything gone through. I'm keeping an eye out now for a good deal on a new prop. This spring I will have everything to get my setup going correctly and safely. I have complete faith in Simon that he builds a good motor. I just had some problems last year that were unique to my motor. When I had these problems Eric was right there to help me with anything I needed. He and I made arrangements to have motor shipped back to him this winter and have it gone through. I hope this clears up some of the questions in this thread.

has anyone here ever gone from a 300 to a 300x, same boat,
same prop. how many rpms did you pick up? I'm just trying
to compare the two, how much difference between them.
thanks.

[ASPB]

We've done it on a bassboat and there is a big difference in the regular 300pm and the 300x.The pm rev limiter kicks i about 6400 give or take and the x rev kicks in at about 67ish.About 3-5mph diff in speed on top.

[beer30]

My rev-limiter kicks in right 7000. I bet you are looking at 5 to 7 mph different. PM Wildman, he has put the two engines on both boats. Chuck

[Dutch]

ok, lets say there is no rev limiter.
trying to figure out how much stronger
the x is.

[WILDMAN]

Every 300x I've run will turn 7000-7100 rpm. The only boat I've had the older 300 and an X on, are the 18 Liberator. There was 8-10 mph difference

[03bignasty]

From what I've seen there is less than a 1mph difference between the two motors. I have eric's motor with the mad intake. I run 103.3 in cool weather. His new intake is faster than the old one. When I put the new one on I'll report on top speed. The 103.3 is with a 32 performer turning close to 6500 rpm's. That is with a stroker bass boat, 3 batteries, trolling motor, fishing poles, tackle and a diet pepsi in the cooler. Bobby ran 103 with his Simon motor on his bullet.

Brent,scalthedog,had a 300x on his mirage, that was not supposed to run over 105 from the previous owner with a 260-280 on it.With a 300x it would run 119-122 on any day with 2- people, and would not go any faster with 1- person. He was running a 15-34 cleaver at 6500 w/ 1.62 gears....as far as longevity i would rather run a 3.o liter at 6500 than a 2.5 at 7500 or more... at 6000 rpms he would cruise at 110...

I just want to make it public that after sending the power head back to Eric this winter everything is running great now. My boat is again a 100+ MPH boat thanks to Eric. He is a great guy and will stick with you to help solve a problem. Not many people like that, out there anymore.

I would recommend him to anyone that is looking to get more power out of there 3.0 liter mercury any day.

What was wrong the first time?

The TPI and ignition computer were not running correctly. That seemed to be the main problem and I had a couple of other little things go wrong.

What it boils down to is I'm the most unlucky Irish man on earth, and if you want to find out what is wrong with something just let me run it for awhile.

Sam when are you going out on the South bay? I want to go boating on the great south bay and need a tour guide. I will pick up lunch or the bar tab.
