protecting windlass motor from water

I have just installed the third motor on our 27's Maxwell Freedom 500 windlass. The two before it rusted through and died.

I know it's an inexpensive windlass and you get what you pay for, but I wonder if anyone here has found a spray or manually applied lubricant that worked to protect their belowdeck windlass motor from water.

The Maxwell site recommends CRC-3097, a Kiwi product I guess because I have been unable to find it. I tried a spray-on sort of wax on the last motor, but doubt it helped much. I`m tempted to slap on some heavy grease.

Appreciate any suggestions.

Re: protecting windlass motor from water

Most windlass owners manuals recommend coating the motor and gear box with grease.

We have had good luck with Petit RustLok Primer followed up with a Monopoxy finish coat. I was giving our drive a coating of Boeing T-9 periodically and while it slowed the deterioration, it did not stop it. For what it's worth, I also have a small plastic bucket, modified to accommodate the wiring, screwed over the drive motor that helps cut down on moisture penetration. See Rustlok Steel Primer

Re: protecting windlass motor from water

try lanolin, like the Forespar stuff or some such. I'd also see why there's so much water getting to it, and work on that as well

Re: protecting windlass motor from water

Its the same wax as the car companies spray into door cavities so if you can find a product for this application it should be OK.

Its worth trying to make a deflector plate that prevents water running down the chain hole from reaching the motor/gearbox.

In my current boat I made one out of aluminium sitting just in front of the motor and bending under at the bottom.
Why don't these things come as standard?

Re: protecting windlass motor from water

Rustoleum "Never-Wet" is an option that I am going to explore. My motor is still clean and shiny, but this new product seems perfect for the application. Of course, it may take awhile to prove it works as promised. http://www.neverwet.com/.

I have a milk jug mounted over my motor ito protect it from the spray that comes down the hole. Seems to work well.

Thanks for the suggestions. Will go with grease, I think, but will investigate Neverwet and Rustlok.

Re: protecting windlass motor from water

Have you considered having a sunbrella cover made as well as using a coating?
