heres my prop slip numbers...

I come up with 15.5%.

Acceptable but not perfect. 12% would only add 2.75 additional mph.
If it gets on plane fine and reacts to trim, you just fine.
A 4 blade would decrease thhe slip but may not add any mph.

Maybe some custom labbing and increase the cupping like a Mirage Plus???

Griff,

You're absolutely correct.

I agree but 2.75mph is a lot. People spend thousands to get that.

On my Formula I lost mph with my Plus's and stuck with my old Mirage's (with added cup). I'm thinking about straightening the hook now.
