| If you have no inserts in the vent holes, that is most likely your problem. Good Merc dealers will stock these in Small, Medium and Large hole size. They only cost about $6-8.00 per pack. I'd suggest trying the medium plugs, and see how your hole shot is. If you are still spinning the motor up too fast, go to the smaller plug. Also, if you spun the hub, that prop should have the Flow-Torque hub in it, and you can replace that yourself easily. Ask your dealer for the proper torque spec on tightening the hub nut.
If you were getting over 5600 with the aluminum prop, I could see the 23P Tempesrt as a good prop for you. They will bite harder than the aluminum prop, and won't deflect, and should bring your RPM's down to an acceptable range. | |
