I have an old 85 Bayline with an 85 horse US Marine, which I believe is a Force motor. 3 Cylinder.
Had new plugs, one new coil as needed. I was able to get to 29 mph on boat speedo. After 5 hours of trolling, with happy trolling plate down, with plate up all it would go is about 13 mph.
Any Ideas, just fouled plugs? It is pushing water out, so the
pump is working.
Is there a way to clean plugs, these are NGK's
