submerged electric motor

[Rob19574]

Not exactly a sailing related question here but I thought I would ask anyway before tossing out this nearly brand-new air compressor.

I have a small Craftsman air compressor (electric and oil-less) that was submerged from Sandy (seawater / salt). I rinsed it off with fresh water and let it dry out thouroughly. Plugged it in and it ran but sounded awful and was emmitting an odor from the motor (slight burning scent). I shut it down. I sprayed the entire unit down with WD40 thinking it may lubricate the piston, bearing and prevent corrosion from within the electric motor. Let that dry out and plugged it in again and nothing happened.

Should I just give up and toss this thing or is it salvageable? I paid $100 new for it from Sears.

Thanks - Rob

If it were me? Just toss it! Not worth all the frustration and I want things to actually work when I need them - not wonder if it will work.

Have you ever heard of a product called corrosion block ?

It's probably toast, but I take everything apart. Take it apart and and find out whats wrong. If you cannot fix it easly toss it.

Personally I don't like oil-less. They are too noisy.

@ Robert -- corrosion block seems interesting. You use it on all your metal? I have not seen it....

Keep it in case you need an accidental fire to collect on insurance.

Go to Harbor Freight and for 39.00 plus 10.00 for extended warranty you'll get a small pancake compressor that works great......if it should take a crap they'll just replace it

I first saw Corrosion Block at the Lauderdale boat show in the 80's. They had a tv running in a fish tank full of water; needless to say I bought some! I have used it ever since, dismantling new electronics and electrical equipment, spraying and reassembling. Seemed to prolong the life of most equipment, but maybe I was just lucky? Even use it on my outboard, a Johnson, that gets daily use as our car and, though usually not the most reliable OB on the market, it has lasted much better than I ever could have hoped.
All that said, however, had you sprayed the motor first it may have been salvageable, but I doubt that at this stage it will help, but it could be worth a try.
Good luck.

Forget the electric motor its toast you burnt it up by plugging it in and running it. Not only did the winding's get shorted out but the bearings on motor shaft needed to be re-greased so the shaft bearings have been overheated and are now locked up.
I always keep a can on board. It does not conduct electricity. The product displaces water at the molecular level. I have used it to save and protect electric motors ,cellphones ,electronic circuit boards , tv's radio's etc..that need to see duty on board or live in a damp environment with great success. Its expensive but with proper use a can will usually last me about 3 or 4 years. In fact I believe the can I have on board now is about 5 years old.
I once saw a display of a working plugged in full sized television submerged in a tank of this stuff.
There are only a few places I have found that carries it. Not sure about this site store?

From a work standpoint (its needs to be able to run 24/7 with a very low demand) the only small compressor that works anymore is Thomas

Most everything else is now some offshore peace of crap that with luck will last 48 hours
