Prop for Mercury Optimax 90

[A3OutdoorServices]

Looking for real life experience with prop suggestion. Have 2013 90 Mercury Optimax with XL Shaft - Going on a 24? heavy tritoon. For guide boat so mainly want for performance and ease on motor and longevity.

prior to a prop suggestion, do you have the height optimized? get the height dialed in, then come back with the answers to the questions in the sticky in the prop forum http://forums.iboats.com/forum/gene...p-questions-and-topics/295058-read-this-first

in fact, you may want to PM a mod to move this to the prop forum.

I moved Scott's post here and left this topic open. We don't need two.

Welcome aboard A3.

Mercury's prop calculator comes up with this. YMMV as you still have to prop it to attain operation within the recommended WOT rpm range

My prop suggestion for family use and screwing around would be the same as the boat when used as mentioned by the OP. Actually, I would use that same criteria to come up with a prop size no matter how the boat will be used, with VERY few exceptions....
