The motor is on a 1989 ThunderCraft. We just bought it and are having trouble getting the motor to idle smoothly. We changed the 3 spark plugs and the fuel filters. We also tightened the hose clamps. What else can we do?
I have a 90 hp force ob. when i run it with the ears she runs fine lets me bring the throttle all the way up. when i but it in the water thru the wake area i can do 4 mph once i'am out of the wake area and give it the gas she dies, any ideas
Sounds like low speed jets need to be cleaned.
