Hi I'm trying different props should I use a LH or RH I 700 hp 1,50 bravo ITS

Call Doug at the factory, he'll point you in the right direction

Post some pictures of the boat!

how did the boat run????????

What is your x or how far is your prop shaft below the boat 4 1/2'' 5'' 5 1/2'' hope not anymore than that?? if your x is 16 to 17 try a 26 or 28 bravo 1. if your higher 17 to 18 try a 5 blade. if your getting good bow lift px 5 if to much like me a p5. I run 32s 5and 4 blades. if you porpoise a lot and drive is tucked under tabs down loose the gas tanks in the bilge.
