Re: 1972 65 evinrude triumph electric shift lower unit problem

A spun hub will cause the motor to rev up but slip. Lotsa revs but slow going. Sorta like spinning your wheels on the ice - or mud if you are a southerner. Is that what is happening?

In agreement with F_R. Wish that vulcanized rubber melt down had been mentioned eariler but no matter.... it would just have cut the answer sooner is all, if the hub is actually slipping.

If that prop is actually slipping, either replace that prop or have it rehubbed. The slippage in the rubber.

Check the prop for slippage by blocking the prop with a piece of wood, then with the plug wires removed, apply a good amouint of pressure to the flywheel nut with a proper socket and a long breaker bar.

If you can turn the engine over, causing the propshaft to turn within the propeller... the hub is slipping.

Let us know what you find.
