Just thought I would share my experience with getting the right prop setup for my boat. I started with an OMC 13x12.5 on the Evinrude 40hp. The motor would easily over rev and run into the built in RPM limiter at about 5900 rpm. So I read as much as I could on this forum and others about prop pitch.<br /><br />I ordered a Turning Point Hustler prop in a 15x12.25. Now the boat runs at 5000 rpm at WOT, right in the middle of the OMC manual listed WOT operating range of 4500 - 5500.<br /><br />I think there was more than a 400 rpm drop, because the motor used to over rev. The Hustler prop is a CUPPED prop without any ventilation holes. The OMC was NOT cupped and had ventilation holes.<br /><br />With the OMC prop, the max speed was 24 mph. With the Hustler prop the max speed is 28-29 mph at 5000 rpm. It feels like the hole-shot is actually better than before. It feels like it's "hooked up" to the water better. I can run on plane with 3 adults at 14 mph, and with the trim pin in the middle hole, it runs rather level... visibility is good.<br /><br />Hope this info helps other with their prop decisions. <br /><br />PS. I also ordered another prop from iBoats because they are on sale, and with the hub system, it was only $40 plus shipping to have the right backup/spare. Now, if I can find a quick disconnect for the prop nut.....
