Re: motor wont run fast
Welcome to iboats.
It could be a lot of things, some cheap to fix, some not so much.
Cheapest: loose wire connection in the ignition wiring. $0
Next cheapest: Bad fuel pump diaphram leaking fuel directly into the crankcase, flooding out a cylinder of two. $15
One of the carbs is plugged up with dirt. $40
Blown head gasket causing loss of compression. $50
Bad coil, stator, or trigger. $100-$500.
Melted piston or broken rings. $350-$999.
Start with the basics, check for spark on all plugs, then compression test each cylinder.
If you have spark and compression, its most likely a fuel (carb) issue.
Oh, and please let us know the model, hp, year of the motor,
