F36 tri-cabin speed

Paul I do not think the 4 blades would help as they are 20x19 if I take 2 inches pitch out I am at 20x17 with 4 blades. Me thinks would be worse than now.

That was aimed at waywego I agree its to much for your boat

I wonder how that would work on our boat -- we seem to be correctly propped at 18.5x19 3-blades. It makes sense to go to a larger diameter, especially since we often run at hull speed, but not sure about the 19 pitch with 4-blades, assuming we are propped correctly now.

I would think You should be under propped , but if your not getting over 4000 then your not .
