loss of drive power in 1964 evinrude 9.5

[hawkfricke]

I was going along fine for half an hour or so and all of the sudden the lower unit stopped driving and the engine revved. Like the drive gears got out of sinc. kind of like i broke a shear pin but it went ok at 1/4 throttle just not at full speed.

Check to see if the hub is spun. Between the pin drive part of the prop and the blade part is a rubber bushing that absorbs shocks to the prop. To test it, make a mark on the part of the prop that the pin goes through, and another lined up with it on the part of the prop that the blades are 'attached to' (really part of). Take it out, get it to slip and see if they're still lined up.<br />If they're not and the hub has spun, a prop shop can repair it or you can replace the entire propeller with a new one. Usually repair is less expensive, but if your current prop is in bad shape you may want to replace it anyway.<br />It's pretty rare to have a gearcase or crankshaft problem causing slipping. Usually you have a horrible noise to go with it.<br />And welcome to Iboats!

thanks for your help. The prop is on its way to the prop shop.
