GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
Bob,<br /><br />We have been having problems with getting the revs up on the boat. The most the boat will rev to is 3200 RPM, and there doesn't seem to be a carb problem. We're trying to lighten up the load on the engine, so hopefully a smaller pitch will do that. Any ideas on the 11"?
I think you are going the wrong way.A 14x17 will get your rpms higher and be easier on the motor.to use a 15x11 would be making the motor work harder and the rpms and speed will go down.Sounds like a houseboat prop is what you are looking for and I would strongly recommend against it.If you did find the prop,the moment you put the boat in gear it will jump.Charlie
Well...I searched a couple of prop sites but they don't even list a 15x11, maybe you could give us a few more details about your problem, what kind of boat, size and weight? What size prop are you running now? A 5.7 should be in the 4200-4400 range at WOT so you are very low, are you sure about your tach, have you tried a portable one to be sure?
Hey bob, you may be able to get your existing prop re-pitched at a prop shop to that pitch.Perhaps you should find out why your only reaching 3200 with the recomended prop before you spend 200$ to get this done.<br /><br /> Jim
Your engine has a 4 barrel carb. Are you sure it operating properly and the secondaries are opening? Depending of gear ratio of coarse, you normally need a pretty big boat to require a prop less than 17"
