400r - does 3.0 sporty bolt up?

[aggiestckl]

Will the 3.0 sporty bolt up to retain the 1.62 gears? Is driveshaft splines the same?

[baja200merk]

It sure looks like the same 3.0 bolt patteren. I'd say it's close enough to make it work but that's coming from a guy that screws them to evinrudes :leaving:

[aggiestckl]

Lol anybody? Anyone have any word on 15" 400?

[JPEROG]

Lol anybody? Anyone have any word on 15" 400?

Word on the street is that the 1.62s are not living very long so far. I guess that he has had it out three times and burned up 3 sets of gears. It will get figured out but hasn't yet.

Same thing happened 5 years ago with the dbr/Simon 3.4+L that was on kirks mirage. Brand new 1.62 3.0 sportys pushing the pinion out the side of the case. It was almost one sporty per river run at one point. :eek: but a 3.0 merc can't make 400 :rolleyes:

Kev,

One things for sure, hes got balls running that mirage the way he does. The thought of that case breaking at speed would over power the desire to run over 125 like he does.

:iagree: Yea especially with a 36p rudder on a non ratcheting case :eek:

it was 135+ :leaving:

It will bolt up however the splines on the drive shaft are wrong. There are issues with the motor throwing shift codes while running. They are working on it.....

[scb]

I have a 3.0L SM 1.75 modified to bolt up to Verado. The 350SCi would destroy the gears in short order. The 400R is much more powerful than the old 350, so I don't even want to waste another gear set to find out.

[powerabout]

time we got a bravo with 1.5 bolted up?
how about the lower from a SEVEN Marine outboard?
duo props with the case out of the water?
( OK so its start in gear stuff till we get the Lenco sorted)

i like that thought processes! Makes sense.

[powerabout]

Surfacing duoprops have plenty of development yet to come
Not to mention merc putting 2 speed box in oil sump under verado ph.

[H2OPERF]

I looked at putting a bravo spormaster on a project im doing but there were a lot of issues. They don't have a reverse gear, its a big case so it definitely would need to be clean out of the water for big numbers, no waterpump , the input shaft is huge and would have to be turned down just to make a pump fit and they are really long. But it could be made to work, huge straight gears less loss, huge skeg to work with and gears down to 1.25. and there are aftermarket ones so no merc crazy unobtanium stupid prices. Dave

350 sci and the 400R junks the standard sporty internals. I will be sticking with 1.75 5.44 Verado Sporty and see how it goes.

the housing doesn't need to be hydro dynamic when it's high and dry over 80. :iagree:

Yup. Brett and I could both strap bricks to our bullets and still run the same top speed :-)

[Mr. Demeanor]

I wonder if the Volvo Penta gearcase would be easier to make work. Dont they have a waterpump in the lower unit? They are very reliable.

Inexpensive and looks like something that might work

i dont know of any volvo that ever had the pump in the drive

[MODVP22]

shift codes??

[Todd D]

Goes into gaurdian when you back off the power. My guess is that the Verado cases are shimmed with no prop shaft endplay unlike a standard 3L. They Have Tried shimming the case b7t that's what eating stuff up. My suggestion is send the ecu to simon and have him disable the shift sensor......

I'm going to email Rick Mackie at Mercury Racing to find out Glenn, I'll reply here when he gets back to me.

Two new ones and 3 used ones so far for me :eek:… After breaking a one at over 100+ mph:nonod: … I really don't want too string my bitch out too much because I don't trust the cases not too mention the cost of replacement cases...

H20 most of the Bravo gear ratio options are thru a combination of upper and lower gears. I was looking at doing the same thing and running 2 starters one for c/r, could be done with efi

[Mr. Demeanor]

I think your correct, its just above the drive but not in the boat like a Merc I/O.

OMC King Cobra became the VP SX. I wonder of the bolt pattern is OMC outboard style.

unless you can find a starter from a direct reverser??

Chris, all volvo sx's use engine driven seapumps, typically driven directly off the harmonic balancer. Cone shifting in the upper gearcase. I think you are confusing them with the short lived OMC Cobra's which had water pumps in the upper gearcase and cluthch dog shifting in the lower gearcase...

[racer]

OMC had a drive cone clutch with pump off the upper gear set, it used 4 gears in the upper.

[mackeral5]

I stand corrected on the omc....

[H2OPERF]

Hey Al, Starting counter for reverse would be really cool. I agree on the ratios, the one I was playing with supposedly had 19/15 gears, that would be like 1.27 . I was ready to do it other than not having any of the tools to get it apart to cut down the input shaft, putting a water pump on the adapter plate didn't seem like too much work. If my current project eats the 3L sportmaster in a hurry I will do it, there are a lot of used imco units around. . Sorry to get the thread so far off . Dave

Wow that's surprising. Is your mid cut down or a Taylor? There are a couple guys down here running them on 300xs for hundreds of miles over 100. One comes to mind an aggressively ported a 3.0 with 170 psi on a skater (brutal on gear cases) and don't have any issues.

ive put 1.62 3.0 sportys under v8 and 8000rpm 3.3L with no issues so far?

[AZMIDLYF]

What LWRs does this Xcat have on it?

The one that Mercury will be coming out with for us to buy in another year or so. It will probably be 9k when and if they get released.

Joe

[powerabout]

Bravo can have 1.5 in the lower and big v8 inside so why cant little old outboard have it?
I suspect cooling them is one issue

Taylor. Bad driving habits are hard to get rid of and expensive… Have to stop the chop:D

[150aintenuff]

Verado to 3.0 case fits but verado needs their specific drive line. I've done fishing motor 3.0 to verado gear case swaps and the case fits on the mount. But. Must swap in drive line and not sure if sporty drive shaft and verado shaft have interchangeable bottom halves under water pump the drive shaft seals the oils pan so it has to be verado specific.

[150aintenuff]

As far as shift codes. None seen if you set shifting like their original case. It's IirC slightly tighter than a cable driven shift cam

[FUJIMO]

No need to adapt the 3.0 litre SportMaster. Mercury Racing has already developed a SportMaster specifically for the 400R, that won't have any issues, and has a warranty. Both the 5.44" diameter 400R Heavy Duty Offshore gearcase, and the 400R SportMaster gearcase come standard with the 1.75:1 gear ratio, and 1 1/4" diameter prop shafts. This ratio is best suited for the larger hulls that the 400R was, and are mounted on most. Whether it be a twin, tripple, quad, or five engine installation, such as last months newly released MidNight Express 43 CC, that utilize surfacing propellers on the 400R SportMasters. Many other multi-engine, 400R boats have been delivered to customers, from such manufacturers as NorTech, Cigarette, Intrepid, etc. Numerically lower SportMaster gear ratios are available, but not yet publicized. To find out more about the new 400R SportMaster's features, contact Mercury Racing at 920-921-5330. And/or call Scott Reichow, with Mercury Racing Propellers, at 920-924-2037.

I received this reply from Rick Mackie at Mercury Racing:

Hi Greg:

I don't believe the 3.0L Sport Master will bolt up to the Verado and if it did - I wouldn't recommend it.

Rick

[mrcrsr]

bolt pattern is the same, a driveshaft would have to be splined to fit. i don't know what they were thinking with the propshaft bearing design in the verado case, i feel that the sportmaster propshaft bearing setup is beefier. i've been getting about 3-400 hours out of gearsets on the skater. people have been running 2.5 cases using the taylor mid, and the gears are way beefier in the 3 litre case.i was thinking about building a verado at one point and had looked at the gearcase situation, so i know it can be done. what works on our stuff may be problematic on a heavier boat though. And I run a taylor 15" mid, yet to break anything, you'd be hard pressed to abuse it as much as I do on this boat.

[powerabout]

its all about weight and prop diameter
think of the ssm with 350hp F1 powerhead on top on a hull 2 of us can pickup

[H2OPERF]

The std thru hub props look goofy on the 544 cases. The question is on a small boat with the big case up out of the water will you need a larger prop dia to get the same amount of blade in the water and if so will it kill the numbers..
