Only Problem with the SSM V is that it is only rated for 750 ft/lb of torque. 480 Yanmar is putting out 950 to 1000. That is the only reason I would consider splitting it. The only units that I have heard of that can support that kind of torque are the bmax and Merc NXT. The Bmax I have not heard good things and the NXT is rather pricey.

I would like to be able to hit 60. But I might be able to live with 50. with the yanmar only burning 20 gph thats a lot more driving for the $$$. Maybe 2 x 480, 4 x B1's

I thought I read in the last issue that the geared up system caused a 4% loss. I looked online but I can't find the article. And my copy is at work. I'll look tomorrow.

Thanks For Everyone's Input!!!

The gear box splitter and rigging is probably going to cost you more than if you just went with wet sump SSM6. You can find them for around 15k. No Bravo style drive will hold up very long to 1000lbs of torque., especially in a heavy 10,000lb single engine boat.
If you do what you talking about, plan on keeping the boat forever. You will never be able to sell it. Put a couple of stock engines in it and call it good.

The geared up system splits the torque so each bravo would only be seeing under 500 lbs of torque. That should work?

The IMCO 35' Nordic is on Lake Perry in Kansas & participated in the Shootout @ LOTO in 2009. I think it has a Procharged 572 in it right now & it ran in the low 80's at the Shootout.

the IMCO boat is now owned by shawn mercer out of lawence. the motor is a 565 with an M-3. i rode on it when brent had it, on high boost we were rolling 95 on gps at a little over half thottle.
they've lowed the boost and the boat ran 94 at the end of the summer still playing with the tune. 3 years ago when brad had it, the boat ran 108 with a quad rotor motor in it.

the splitter box hasn't had problems, it was made by a company that builds couplers for multi engine pulling tractors. it's bullet proof to say the least, it's a gear driven deal.

The only problem with the splitter is IF you do get the boat in the air and it leaves or re enters the water with only one drive making contact with the water ALL of the torque for that instant will be going to the only drive that is in the water. BANG

the only time he will be leaving the water in a 36 cig with 480hp is when he puts it on the trailer!! I had a 35 mistress with 1200hp & it was no small task to get the drives out of the water!!

But if he does - you can kiss the drive gone.
Even if one drive aireates getting on plane it will put all of the torque on the other drive.
And 480 HP from a diesel engine isn't the same as 480 HP from a natural asperated gas engine.

I would like to be able to hit 60. But I might be able to live with 50. with the yanmar only burning 20 gph thats a lot more driving for the $$$. Maybe 2 x 480, 4 x B1's

I don t know what the gearbox costs but it ain,t gonna be cheap and think they are any used ones to find ,just buy one or two 480,s and give rik from arneson a call an he hook u up whit a pair inline asd 8,s and you have a bullet proof setup for the same or even less $$$ then gearboxes and bravo 1 drives wich are gonna break and best of all it will still be sale aible!!

I have a 32 hustler whit 2 qsd 320 on xr drives and hit the 65 mph just dailing in but hoping to see 70 one time but it,s fun driving and one hell of a accelaration from 1900 to 3800 !

the cigarette is much heavier You never gonna see 60 I hope you get it on plane on 1 480

Yanmar 480HP $40,000, Geared up System $5,000, 2xB1's rebuilt $10,000 ---Total $55,000

Yanmar 480HP $40,000, Arneson $26,000, Bow thruster $5,000--- Total $71,000

2x Yanmar 480HP $80,000, 2x Arneson $52,000 --- Total $132,000

... A lot of savings. Obviously 2x Yanmar would be the most ideal setup... but there is a lot to be said for $77,000 savings. I'm not sure I would want to have to maneuver a single with Arneson without a bow thruster. I've heard that can difficult. Plus if a B1 breaks... not too difficult to have a spare and swap off. If by chance you were to mess up an Arneson I have not idea what the turn around would be on repairs.


As for the one unit aerating and the other blowing... I thought the torque was split no matter what, but I can't find anything to support that... I'll call geared up and see what they say.
