I have a 1987 Mercruiser 350 in a Malibu Ski boat
not everytime I take it out but it has happened several times this summer
after about 40-60 minutes of running great and pulling skiers and tubes the engine starts to backfire badly.
it never stops running but not alot of power and alot of backfire. backfire on power up and while trying to accelerate.
after about 40-60 minutes of tooling around at low speeds it starts running great again and no further problems for the rest of the day. PLEASE HELP !!
