looking to borrow a 13x19 yamaha pop to test. I was given a 13x17 on the boat and would like to get a few more knots.

max speed is 34knots compared to yamaha reports of around 40knots.

where are you at?

what is your boat?

How is the motor height set up?

What is your WOT rpm trimmed out?

Unless you have a fault with the engine set up, you will most likely just trade wot rpm for pitch, and not change top speed very much (if just changing to a bigger pitch in the same type of prop)

Is your yammy 17P prop standard, or has it been worked already?

cheers
