[QUOTE="lovedr79, post: 260060, member: 5106"] today while out on the river motor ran fine, was getting 20mph loaded with two people lots of gear. fished for awhile started back up river suddenly lost power. all i could get out of it was 6.5 mph. sounded like it was over loaded. cutt throttle back nothing, choked out. fuel line bulb wouldnt get tight....... took the pickup tube out of the tank, primer working properly just wont get tight. no fuel leaking out anywhere. i came home pulled plugs out they were slightly yellow. fuel filter clean, bulb tight after a squeeze or two. how do you check the fuel pump? i pulled it off but wasnt sure if it was like an old V8 fuel pump. i can blow throw it the way fuel flows, but cant blow through backwards. makes a whistling sound when you blow through it. you can also free rev with the throttle only but as soon as u put a load on it, it becomes very sluggish. not many hours on this motor either.
