Re: 80hp mariner outboard
I've got a 1981 Merc labeled version of this motor. It's a nice, smooth runner, if a bit thirsty. I've been having lots of electrical problems this summer, as the wiring harness rots from age. Carbs are very sensitive to fouling, but easy to clean and rebuild. If I could solve my recurring electrical problems, I'd fall in love with it again.
Go to the Merc/Mariner forum, and you'll find lots of experts.
