Hi have to say this site really seems invaluable. I hate to go over ground thats already been covered but bear with me. I've got a 70 hp Yamaha 2-stroke about a 93 model i think. Engine starts fine and runs perfectly, problem is when i back off the throttle then go to accelerate again the engine will only run at an idle speed while in gear. In neutral the engine can be revved as normal but with the load of the boat on it, it wont respond. If i let the engine cool for a half hour or so it returns to normal operation until i back off the throttle again. I've installed new water/fuel seperator, fuel lines and plugs but problem persists. There is one segment of line i didnt replace and probably should, but i cant understand why it would run perfectly until i return it to idle. i should point out too that when it does play up and run at minimum revs any further attempt at acceleration will cut the engine, yet it will start again no worries. It may just be coincidence but the problem started when i had to slow down for a 3ft wake of a yuppy vessel. Ironically it was a big Riviera and i quit working for them the previous week..thats karma i guess. Any thoughts appreciated thanks
