Max, IMCO, Teague Platinum, (basically shiftable Bravo style outdrives), are not up to the hp/torque that current technology has been able to generate.

Is the NSX Merc skinny trans/Gimble/Six drive the answer? I know that I would'nt be getting a new boat, (we are talking more money, slower boat). If this is the answer, I would have been exceedingly better off to be 2 years younger, (I'm 59), and been introduced to the NSX tranny concept now. What do you think?. Quent

Have you run the BMax HT, it's warrantied to 950hp/tq.? If so, how did it hold up?

Yeah same hear thats why we called and talked to them personally.Trust me if they had no failures they would warranty 1000hp motors.Konrads are only guaranteed for like 700-750 ft lbs of torque I believe not positive. I think there is a market for a drive that can handle more abuse thats why they all try to build them. Calling Bmax tomorrow about the HT to see if my gimble and hyd streering will work on there drive. Then Arnesons to see how much to change everything over. Keep you posted

I'd probably trust the Arneson over the others. I would think you would get some more top speed with a surface drive, too.

My motors were blower motors that made about 715 hp and 750 ft. lbs. This year we made some changes to the motors and they'll probably be over 800 hp maybe even 850, I'll find out today...

From the documentation I have the warranty is for 950 hp/tq in a 15K boat.

Here's a few pictures of the upper gears. (5 inch diameter.) These were taken a few weeks ago and with 70 hrs there's not much of a wear pattern on the gears. Just gotta watch your gear ratio, these come in 1.30, some people have lost speed, I only lost 2 mph from 1.50's.
