Location: Cedarburg, Wisconsin | The info I found on your motor calls for 5500RPM WOT. So, I wouldn't worry about the revs unless you were consistantly going over that. If the prop is the same vintage as the motor, it will definitely have a rubber pressed in hub, so a spun hub is very possible. Also possible is that the prop could have had the cupping on the blades worn down from use, or it may have been modified for some reason. Check with your fingers at the blade tips and back edges for a distinct cupping. If there isn't any then the Stainless would behave more like an Aluminum prop and tend to lose bite cornering or climbing up on plane.
I'd see if I could borrow a different prop of suitable pitch and give it a try. That will probably fix the problem. If it's a three blade prop, changing to a four blade would help it carry the weight of your rig and still not lose grip. Mercury has some very nice props that will fit your motor with the correct hub kit. A Rev 4 or Trophy might be more of what you need. Hope you get the problem sorted out. |
