I just had the motor into the shop to have several things done including rebuild carbs, impeller, tune up and so on. Anyway, I also told them to replace the trim motor if necessary. They checked it out and said it worked fine even though it was badly rusted, and that they did not see any reason to replace the trim motor until it quit because it is fairly expensive. I tend to agree.

I am thinking of applying some type of protective coating to the housing for the trim motor to try and protect and preserve it. Any suggestions? I was thinking of something like a spray on coating, possibly an automotive undercoating material.

LPS-3 spray has never failed to protect my gear, even in saltwater environment.

What prep did you do prior to spraying? My trim motor housing is very rusty. While I want to protect it, I am cautious in sanding/scraping fearing I will dislodge the last remnants of the housing.

Do you have a manufacturer for the spray?

In doing a search I found this description -

LPS3 (11 oz)
This heat-resistant, tacky and throw-proof lubricant offers a number of benefits for the professional mechanic as well as for the seriour do-it-yourselfer. It anti-corrosion and wear-protection properties, combined with its penetrating and adhesive strength, make it the right lubricant/protector for all such components for which no specific lubricant is recommended or where other types of lubricants (oils, greases) may be used. LPS3 spray combines the advantage of a good penetrating oil with those of special oils and greases in a single high-performance product. This makes it ideal as the all-around lubricant/protector for parts such as door, hood and trunk hinges, latches and striker plates, clutch, brake and throttle rods, linkages, cables, levers, shift levers, window winding mechanism, seat and sun roof tracks and controls, chains and cables, and other parts/components exposed to water, salt spray and dirt.

LPS-3 looks like a great product and I think I will try it for some other applications and maybe the trim motor. I was actually thinking of something with more body to it, like a spray on undercoating that might be used for automotive purposes.

undercoating works as good as anything. Nothing will stop the cancer....scrape(gently) before you coat and use a good primer.
