Prop Size on Scarab 26
I'm new to this game and need help with selecting a prop size. I have a gen 6 502 with lightning headers, comp cam intake duration-283 exhaust-290 lift w/1.7 intake-.566 exhaust .575 lobe angle 114 degrees, msd 6m2, reprogramed ecm, comp springs, roller lifters, pushrods and roller rockers. The heads are stock with minor work done to them. Also have hardin spark arrestor, fuel pressure reg. The boat cam with a 454 and a 3 blade prop, i smoked it the first 10 min. in the water the day i bought it so i dont know how it ran with that 3 blade prop the 454 was stock. i'm guessing i need a 4 blade to go with this 502 due to the horsepower increase. Any info and help i can get will be appreciated. Thanks,
New performance boater
