Pat, What is the dimension from input to output shaft and what does a pair of drives go for? A PM will work also.

Yes I would love to know because, you have really peaked my interest...I have never been hard on the boat, either out of the hole are @ WOT...but damn it sure would be nice to just hammer the chit out of it sometimes...

If money was not an object, I would go with a Weismann or Arnesen drive. I would not go with a #6. The #6 is just too heavy and inefficient... especially on such a finely tuned boat. I Love the RPM cat! Steve did an awsome job in its design and construction.



Could not have said it better myself.

#6's are even being used on the 21ft ski race boats.

John,

I just noticed that the trim tabs on the 21' ski race boat are mounted at 1/2 deadrise. This is what I am going to try next on my boat. I am pretty sure that they are running the long tabs on that boat because of the extra weight of the #6 drive.

Chris

p.s. hope you get feeling better soon

I think that the NXT drive might be a viable option also. RPM has set up a boat with one of these, and it worked well according to Steve. The weak link in this system would be the stock mercury tranny. An upgrade to a good Bam unit would be in order.

The guy with the twin turbo Thor that lives near me is running the NXT drive, and likes it. With his motor de-tuned to 1100 hp, by turning the boost down, his first test run was 133mph.

Chris

p.s. with the boost turned up... his motor produces north of 1800hp on the dyno.

So are you saying there is a guy that is putting 1000 pluss hp through and NXT drive I know they are rated for 800hp, what is the warrnty on the nxt, Steve did the Norway boat with a 662 (700) anda Nxt drive, they did a stage 1 upgrade on the engine and it runs great, maybe an option...
