newbie here, any opinions appreciated.
I have an 04 50 hp yamaha 2 stroke that has been running great until the last 6-8 trips. I'll try to describe but I'm not real mechanically inclined so please bear with me.
-Motor starts normally and takes about 20-30 seconds to idle down -
-I then shift it into forward and throttle up fairly quickly but nothing like a bass fisherman taking off.
-So far so good -- motor runs fine as long as I want to run it BUT once it is good and warmed up and I stop - getting it to throttle back up can be problematic - especially under any kind of load - such as driving it back onto the trailer. Not always - just sometimes. The longer I run the motor - 15-20 minutes normally about 3/4 throttle the more likely it is to act up. Short trips don't seem to affect it as much.
It sounds like it is choking out, and simply sputters and putts - sometimes killing the motor all-together - maybe like the fuel line is sucking air or even water in the gas. It has always throttled back up eventually getting me back to the ramp - but something is not right.
I've changed gas and put on new a fuel line. I just had it in my local shop and they changed plugs (old ones looked good), changed oil in foot, and replaced impeller, adjusted the carb and the idle setting. I can take it back to them as I feel they have always treated me fairly but I don't know if I am describing the problem accurately enough for them to diagnose problem.
Any ideas ???
