Hi, New to this forum. Having engine rebuilt after bad winterizing experience. 5.7L 350 EFI 290 HP, Alpha 1. Boat Regal 1988 233xl. The original 350 in the boat had a 14/34 x 19 Stainless prop. I was wondering whether a move to a 4 blade 14.3/4 x 15 would be comparable to 14/34 x 19 prop there now? Thanks Roman
