How do I stop my engine giving me electric shocks.

Hi there RIBnet and people.
I have a problem with my 25 Merc as it is giving myself and other people electric shocks, especially when it starts up and is warming up. It surges the power and goes to cut out then kicks in and revs back up and then does it again and again for a couple to sometimes more mins. It is just a pull start with no battery but I can not seem to figure it out. Any advice out there on where I should look to figure it out. ????

I would check all your electrical connections under the hood including kill switch wiring and ht leads sounds as if there's a short somewhere.

Sounds like HT leads. Try running it in the dark with the hood off. You'll see if it's HT leads. They'll sparkle.

Thank you for the advice and it is greatly appreciated. I will have a look over it all today then if I have no luck I will try the nite deal and running it to c. The only problem with that is that it only does it when the cowling is on so it may not show it at night but I'll try none the less.
Oh yea about the Welles it just so happens that they are my rubber of choice and even though I wear them with a cape, it still seems to happen. I must need better gumboots I suppose.

Massive thank you and appreciation for your feedback. You are all quality people obviously and I hope your days go well and for you all. Happiness is a choice and happy boating people.

check that the tell tale pipe is not split and spraying water onto the plugs - this has been known to happen.

You'll still see it if the HT leads need replacing even if you're not getting a shock. Make sure it's as close to pitch black as possible though.

I would say that if it only does it with the lid on then I would definitely check connections. Poss a trapped wire when the hood is on or also check ht leads as that engine they run very close to the cowl latch at the rear of the engine. I'd've sure it's something fairly straightforward though.

The stop button wire is broken beside the throttle cables where it goes at the tiller pivot. Disconnect the yellow and black wire and use the kill switch on the lower tray and see what happens. The lower tray on that engine is fibreglass so cannie see how your getting a shock through the hood catch.
