I do use Seafoam. My pontoon is now 11 years old and all the rubber in the motor dry rotted. Found a spark plug wire shorting to a bolt head. Then had to replace fuel pump. Took 3 trips to the doctor to get it running. Lucky it didn't catch fire. I need to get confidence back in it. Left me stranded a couple of times, but did work when we launched it last.

When in the middle of GRL, the motor won't start, and your trolling motor can't keep up with the wind, and there is no boat in sight--It's a scary feeling. There is no triple A for boats.

I have a pontoon because that is as close as I want to get to the water. I should be out there in another 18 days give or take.
