Hi Charles. I would add Marine PRO to every tank of boat fuel. Marine PRO cleans fuel passageways, lubricates, stabilizes fuel, and provides corrosion protection to upper engine areas. At least two times a year I like to add a can or two a low tank of fuel and run the engine under load (hole shots, high RPM).
