Marine chevy 454 w/SEI alpha one outdrive
Has any one tried use a 454 with the alpha one outdrive?
 
If you go easy on the hole shots and baby it when planing you might be able to make it work for a while. The biggest problem is the drive not being able to handle the torque of the 454. It's just not the optimal setup. Maybe if you change the gears in the drive?
 
My 250 CC has a 454 and Alpha 1. 30 years old now! I go slow out of the hole, and never go full bore with it. Lot's of torque in a 454, just go easy.
