Yesterday my neighbor call me over to look at his motor on a pontoon boat. I've attached a picture of his motor .... I've never seen corrosion that bad in my life. The motor is a 3 year old Torqueedo electric motor ..... any thoughts on how that could happen in 3 years ? It has never been out of the water in those 3 years and it is a fresh water lake in Phoenix Az. I would have thought the Torqueedo had a annode installed from the factory. Thanks Rick

Re: Severe Motor Corrosion

Looks like his fresh water lake has a lot of disolved salts & minerals in it. A not uncommon thing west of the divde.

Does your neighbor park his boat near other boats on shore power, or does he use shore power him self? Any funny electrical work done to his boat?

Re: Severe Motor Corrosion

He needs to find out where the stray current is around his boat. I would not let anybody get into the water near his boat. Stray current in the water can cause muscle spasms which can cause drowning.

http://www.youtube.com/watch?v=V2vEpuSi1iY Marine Electrolysis safe guard, I don't know if it works but it's one way to address it.


http://www.yachtsurvey.com/corrosion_in_marinas.htm This article discusses Marina Electrolysis

It would also be interesting to know just how many if any anodes are mounted on his electric motor and/or transom.

That thing looks like part of an artificial reef.

Re: Severe Motor Corrosion

He also needs to look at his toons for pitting and corrosion. If this happened to this motor, it could be happening to the toons as well.

Re: Severe Motor Corrosion

I would say something si wired wrong, the only way you can ge that much sorrosion is that short of a time is with current going through the motor, is the boat grounded like a car possibly, I saw a toon that the guy wires in some stuff and ran a frame ground and it really tore up the tubes, boats need to have a closed electrical system not open ground like a car.
