Heck i top out at 5200 (max 5500 for my motor) and i wish it was a bit higher (not enough to drop money on a another new prop though).

Joe, I'm not sure. She runs great so I'm not messing with it. I am at 32 knots@ 5400. I'm certain I could get more RPMs and a higher top end with a different prop but I'm running a stainless prop with the specs the Yami dealer recommended for my boat and motor.

I usually only run between 4200 and 4500 anyway so I don't need a higher RPM output. 4500 puts me at about 26 knots.

Ya, 42 to 4500 sounds like the sweet spot, I get a little less speed than that, I must weigh more than u.....

Gup, I use to run at about 22 23 Knots but I had trim taps put on last year and pick up a few knots
