Still searching for the best version for me.
RED version was sub par performance
SCD version is closer, 17 too much pitch. Sent propeller to have it repitched n balanced. Will see after it arrives with modifications...

I run a 3 blade 14 pitch on my HB Guide with an F70. Gets up great, spins to 6100 and tops out at 36 mph wot. Can also run at 5000 rpm at around 26 and burn 3.5 gph. It’s not a PowerTech though

What speeds are you looking for? A flat bottom boat isn’t a speed demon to begin with. There’s such a thing as “hull speed” which is a speed threshold that when met you will actually begin to see speed decrease with more horsepower due to weight and resistance.

Sorta agree with a true flat but hull has an 18" wide pad.
