20' prop

[Blue_Heron]

The WOT range is 5000-5600. I would like to prop for 5600rpms. I'm pretty sure i have a 19" laser 2 on it right now. I'm going home this weekend and I will double check. A lot of people have mentioned mirage plus 17" on them. The laser 2 has a diameter of 14 inches where the mirage has a diameter of 15 1/2 inches. Just trying to find a prop that will give me the 600rpms if possible

Sounds right. My spare is a Laser 19P and does about like yours. Higher top end speed, but lower WOT RPM. And it doesn't like to cruise below 25 mph, especially with the boat loaded for fishing. Not a good thing if you're in heavy seas. If you go offshore at all, You'll like the Mirage a lot better.
