I must have missed the press release where everyone else was sponsoring the drives that were breaking and bleeding everyone of their "left over" $$

Thanks for the replies! Obviously with an endless budget I'll be looking at arnesons. Also, I would be looking at a brand new/retail market prices - I'll be looking on the used market, so take 50% off those prices.

I'm on a budget for sure!
Maybe I will try and get Bravos to survive. Despite the power and large boat, this is a fresh water lake boat that I'll mostly cruise with and no big waves to contend with.

I had a BMax that was perfect for 5 years behind 720 hp. Lost about 2mph but worth not being on the trailer.

Is the speed loss due to physically larger gears in the upper?

Yes.

Also, pretty sure the older lowers were not as efficient as the current ones.

What is the length of the 6M kit from hull to tip of prop shaft? If I remember correctly the 6M is a direct bolt on replacement for a Bravo, correct?

The kits are 4" longer than a Bravo on standoff box. The kits are the same as the Bravo Conversions and included all the components needed to convert from the Bravos to the Arnesons.

SSM or other is not an option.

What is the best drive? Bmax? IMCO?

I've heard an XR is no stronger than a X and some ppl get those to live behind this much HP....

Just seen your post. Did you end up doing the Arneson conversion yet ?

Also question for Rik, the A/T 37 step hull runs with props turning out and i understand the surface application is typical for a turn in set up. What would you recomend for prop set up ?
