Whats it got on it now and whats the WOT rpm
4700 and its currently an 11. Marine service center dude suggested a 12.
I had it backwards, it had a 13 we replaced it with an 11. We wanted to get more RPM as the motor was laboring with the 13. The motor works best at 5000 to 5400.

But you're maxing out at 4700 with the eleven?
The 11 should put you right in the RPM range
I'm running a 12 1/4 by 9 pitch on my 17' Sweetwater, same motor, and getting 5950 RPM with just my wife and I on board. Had the family out Sunday, 4 adults and 3 teenagers and she was reading 5400 at WOT.
