I have a 1997 Luhrs 320 Open and am Repowering with GAS engines! The boat had Marine Power 8.0 454 MPI 330 hp engines, and I am repowering with Crusader 6.0 366 MPI 375 hp engines.
My question is: What size props do I need? I was running 21X25 4 Blade Nybril Props with the big blocks. With the old motors I cruised at 3200rpm, I'm told new motors will cruise at about 4200rpm. I'm running 2.55X1 Transmissions, which was what old transmissions were! Thanks for any help
