I have a 50 hp yamaha on a 20 foot pontoon when i idle the motor it runs ok.When try to increase the throttle it starts to increase in rpm but when it starts to move it will get some speed but much slower than last year. After a while it just slows down and shuts down. I have changed the plugs no change. I need help I don't have a repair shop close to me. HELP!

Hey Donnie, Welcome aboard! I have moved this over to the Yamaha OB section. You're more likely to get help on a motor problem over here. Good luck!

Re: Motor trouble

Please provide a little history, has the motor been sitting, is the fuel fresh or old, have you change the fuel filters? and has anyone touched the carb.
