2008 R25 windshield wiper motor burned up

[shawnpb]

I recently purchased a 2008 R25, 2nd owner, original owner wasn't really good with general maintenance. During my Survey, all wipers worked, but one was questionable. I was fine with it, but two weeks later while performing more checks, the questionable wiper motor almost burst into flames. I ran it for about 10 seconds, it was moving the wiper arm very slowly so I quickly turned it off. 10 min later it started smoking and the plastic housing started to melt. No fuses or circuit breakers popped. I tuned off the engine and shut everything down. The two wires supplying DC voltage & current had all of the insulation melted off so I broke apart the plastic covering and cut all the wires to the motor. After about 10 minutes, I started the engine & headed back to dock. There's a 30Amp fuse labeled WIPERS, but it was in tact with no damage. 30amps seems very excessive, but that's what the manual calls out. I'm sure the excessive heat was due to zero use over the years and poor maintenance, but something in the electrical system should have prevented this, a fuse a breaker...anything. I'm going to replace all four wiper arms and motors. If anyone has any ideas or thoughts, I'd love to hear them. THANKS!!!

Wow, wiper park fuse, I never saw that, who would would have known!!! I pulled the Wiper fuse as well and it didn't do anything to my amazement. Back at it in a couple days. Thank you soooo much for pointing me to this post.

The Marinco 1000 series are a piece of crap. I had this melting/fire issue as well. The shaft gets salt into it and corrodes and there is no way to disassemble it to clean/maintain it(designed that way). It causes the shaft to bind up, the motor tries to turn it anyway, it draws huge current and melts. The fuse doesn't blow. Likely needs a fast blow or smaller fuse. Two of these have burned out this way on my R25, actually three (I replaced one with a direct replacement and I'm just waiting for it to do the same thing.).

I replaced them with something else that didn't have as much power. It's amazing how few providers of marine wiper motors there are. Someone interested in some basic quality could make some good money.
