Mine....454 ci. 330hp, ~5000 lb boat, never lasted more than two months. Rebuilt it, blew it up. NEVER did hole shots. Bought the Bravo. Even a 32 Pachanga is putting less stress on an alpha than my Baja did. Hp to wieght ratio thing at work here. G-Force runs twin alpha's on his 32 also, and has also never had an issue that I know of. But I think he is adding Bravos due to bigger hp motors.
Just don't want anyone to go thru what I did. And the gear ratio was somewhere near 1.36, but not really sure what it was. Been 7 years!!!! Happy with Bravo performance. Never had a hp related issue with a Bravo.
Take care......off to bed now. 5:00 start time in the a.m.!!!!!
