Correct Prop

[CaptianMark]

I just took delivery of a new 2017 16 foot with a 40hp Yamaha. I am now into my 3rd hour of break in. The prop is a 12,1/4 X 9 G. At YOT I can only hit 4800rpm 16 mph. I am looking for 6000rpm at YOT, and to operate at 5500rpm / 20mph. Any suggestions?

The dealer should make it right.

Any luck so far?

Curious if your dealer helped you and and got this issue solved for you?  Was something up with the engine, or was it just a matter of the engine hole mount and prop pitch size/type?
