Prop shaft winterization....

[Mark42]

The owners manual says to remove the prop for off season storage and grease up the shaft. I guess this is to prevent the prop from corroding onto the shaft.<br /><br />I am storing the boat outside. To prevent the propshaft from rusting, I was thinking of applying grease, then wrap it up in food plastic wrap to keep the water out.<br /><br />Anyone else take any measures with the prop/shaft over the winter?<br /><br />Mark.

Re: Prop shaft winterization....

The main reason to remove it would be to prevent snow from getting in there to a point where it will melt and turn to slush and refreeze and break the exhaust tube in the gearcase. That can also force the prop backwards and pull the propshaft and bearing carrier out a bit and allow water inside to freeze and really destroy the gearcase. If you store the boat with the motor down, it shouldn't be a problem. For motors I winterize for customers, I splash some antifreeze in the cavity and cover the middle with a plastic bag. Don't cover the whole gearcase with a plastic bag. Condensation can build-up and be just about as bad as rain or snow getting in there. The propshaft shouldn't rust, but if you run in saltwater it might a bit.

Mark,<br />I think that is a very good idea. I am fortunate to have inside storage for my boat, so I cannot speak from experience. However, at all of the outdoor storage lots I have seen, the boats are shrink wrapped, including the motor lower unit and prop. <br /><br />I do pull my prop and grease the prop shaft every fall, but I don't take any other measures to protect that area.
