Another Prop Question

[McGillicuddy]

Specifically, what after market prop? Model?
Where is your anti-cavitation plate in relation to your keel?
Does your bow rise when you take off (hole shot)?
Is the 5400 rpm WOT?

Bushwacker has a PowerTech ELE series 4 blade that here very happy with on his Etec 150. But his is a 20 Seafari with a bracket. 21 is bigger but that shouldn't phase your Etec, it has plenty of power for the 21.

I think your pitch is right but maybe your motor height or prop shape is off.
