finding the right prop

[Old'sCool]

I don't think there's one that covers all situations, kinda like the multi boat theory. I'm running a Solas 4 blade 17 on 23' w/Hermco bracket, 250 Yam 2s. Cruise high 20's-30, tops ~ 40 but holeshot is good and lower planing speed when rough. Typically ~ 2mpg. The 3 blade 19 runs faster and will hit low 5k rpms, holeshot is acceptable, but have to run a little too quick when rough.
