Are there any capacitors, or the like, on a 2GM20F? I got a pretty good zap as I was scrubbing the connection at the raw water inlet to the cooler (heat exchanger).

The batteries and the little solar panel are removed from the boat.

It might have been a pinched nerve, it was very cold and my bones are getting creaky in my old age, but it involved my whole arm and shoulder, just like years ago when I put a knife in the toaster.

Static charge built up on the shrink wrap? The prop shaft is disconnected.

There are no capacitors on a gm engine and everything is 12 V. Could you have some how gotten a 120V fault to the block. Trouble light or?

Is shore power connected to the boat???

If so and you have a multi meter check the voltage between the engine and ac ground.

Would not be the first boat with the hot and neutral reversed, either in the boat or at shore power connection.

If it was today that you were working on the boat (in Salem) it was the boat trying to ask you what the heck was the matter with you!!

I had no idea Yanmar made a toaster....

Is the boat on the hard? I've been zapped by my boat while it's sitting on a trailer with having no source of power with batteries removed too. I got zapped on lifelines and seacocks and thought it was because the boat is parked under high voltage power lines. I was thinking maybe the boat is getting some sort of inductance reaction from the power lines. I've been trying to figure it out myself.

Did you see the spark or was it your funny bone?

Kettlewell · 25-01-2013, 15:53

My first thought would be something connected to shore power is not right.

LUKE!! GO WITH YOUR GUTTTttttttts. Check your GROUND's I think you have a FLOATING Neutral. May the FORCE be with you! LINDA

The boat is on the hard. We were not connected to shore power.

I wonder if the shrink wrap can build up a charge...but a static discharge would be one short blast, not a prolonged toaster zap.

It was probably my funny bone.

But I get to believe what I want believe, so I say I was probed by aliens. Probably wanted to understand what drives a human being to be on a boat, on the hard, in 4F weather, with the wind howling, in the middle of the night, under a propane lantern, cleaning an engine with a toothbrush.

Neo, it sounds like you're experiencing the same thing I am on my boat.

I'm on the trailer parked at a storage unit so no shore power, Even batteries removed and still get a constant current that I feel on the lifelines (that's a pain when walking on deck and getting zapped through pant legs) and even feel on seacocks. Feels a little like a low level AC. I was thinking there's some sort of reaction because I'm parked under high voltage lines, but not sure what it could be.

I would be scared the lightning would get me when a storm comes!

But I understand it though!!!!

Neo... This is why we will always be the superior race.... It shall always remain a mystery and the ultimate need for an alien race to understand why.... For us select humans in the sailing world to do the myriad of activities that defies any logic whatsoever...
