Re: merc gas?

Use SeaFoam gas treatment. Napa auto stores /shucks also carry it. I don't think you would want to run more than 1800-2000 rpm on muffs.

Re: merc gas?

What we call "muffs" is an attachment to feed water from a garden hose to the engine for running it out of the water, BL.

They are a semicircular frame with large suction cups at the ends to fit over the water intakes of the outboard. On of them has a connection for a garden hose.
