I have a 1988 Force 50 HP Model #507Y8C that I bought new on 1988. The problem that I am having is that it runs speratically on one cylinder while on the water. I can not get it to run bad while at home on the hose however every time I go on the water it does this. I have cleaned the caberator except the needle and seat (Scared without new parts available in my town) put new plugs in and none of this helps. I am afraid that it is one of the coils but I cannot figure out shich one because it won't quit at home. any suggestions would be great.
