I have a 1996 Yamaha C75TLRU with oil mixed and I got an alarm buzzer today after a few minutes of WOT. After backing down and checking pee stream which was present but maybe not as strong as normal, the engine ran well for a bit then seemed to bog down or miss intermittently while at cruise (3500 rpm) on the 10 mile trip back to the ramp.
To describe the missing or hesitation, I originally misidentified the symptoms as the affects of wind gusts as there was no audible engine noise irregularities or drop in rpm. The motor did seem to be running a bit rougher than normal but could be do to running hot? I don't have much seat time with this setup and have been running 4 strokes for so long I don't really know what is normal for this rig besides the smoke and noise .
I have a manual ordered but would like some feedback on my assumption that I am looking at a probable water pump / impellor replacement vs. fuel, carb or electric problems. Any help with troubleshooting would be appreciated.
Thanks,
