Re: Prop slippage
"Struggles" really doesn't come across as "slipping". It more or less plants a picture in ones mind of a engine shaking, viberating, attempting to overcome the impossible.<br /><br />If the rpms increase and the boat slows down, that would indicate a possible slipping problem.<br /><br />Have the engine in gear (engine not running), block the prop with a block of wood, try to turn the engine over via a breaker bar and socket on the flywheel nut.<br /><br />If you can crank the engine over with the breaker bar with the prop blocked, obviously the prop hub would be faulty and slipping.
