Yes it's a boat motor, use it on a 10 ft john boat. Runs like a top.
The JB weld for plastic that I found, says not to use on gas tanks. I did find a product called Seal-All, it's Gas & Oil resistant. Going to give it a shot.
I empty the fuel tank when not in use, so this might work. Think I'll try fixing my cracked windshield wiper reservoir on the work truck too.
