Bought a used 2010 17ft skiff with a Honda 90 with less than 300 hours. Had a full service done on it immediately. No issues found by the shop. Everything seemed to be fine and it purred like a kitten. Took it out on a local lake and idled around quite a bit perfect. Then I opened her up and after about 15-20 minutes of running around 4-5k rpms it started started having issues. It would lose power and go into limp mode. Turned it off and back on and everything was fine again for a few minutes and then do the same thing over and over. Took it back to the shop and they said it had no codes and everything ran fine - mechanic couldn’t find anything wrong. Took it out several more times after that and the same thing happed again after running at cruising speed for 15-20 min. Never a problem at idle speeds - runs for hours. I suspected a fuel issue so I installed new water separator, fuel filter, fuel pump, hoses, bulb, connectors, running non-ethanol fuel, tank vents are open and clear, no line leaks, and bulb stays hard. Also doesn’t seem to overheat, water pump is new, strong cool pee stream. Oil level is good and no alarms on console. So what am I missing - what else would cause a Honda 90 to go into limp mode after 15-20 min of running at cruising speed?
I have a recent video of it acting up but can’t seem to post on here.
