Our marina has 89, and that is all the LSM-550 requires.

Yep, more cubic inches (450 Vs 376) and fewer parts to break (no supercharger) makes a lot more sense to me! Now if I could only afford a couple...

Raylars would be wild in the 292 I thought about it,but for probably less money I can be in a 35,38 next year

Wild is right! I have to think with the weight savings and going from 640 to 1100 HP, low to mid 90's is very possible. Probably turn fairly tall 5-blade props and get better mid-range mpg than the stock 6.2's!
