- Mainship Pilot 43
Taking our Pilot 43 out for the first shakeout run yesterday. After warm up under load at trolling speed, I increased the throttle to 50 % power, then to 100 % power, which at this point the engines (Twin Yanmar 6LY 440's) started to "bog down", never reaching WOT RPM's. Actually reaching about 60 % on port and 70 % on starboard. Oil pressure, water temperature normal. Once back to 50 % power all was OK.
Should I assume a fuel problem? I'm going to check the Racor's and secondary fuel filter's. I was also thinking of running the RPM's at the dock not under load. Good idea?
What would be the best progression of troubleshooting this problem?
Crazy as it may sound, I have never had fuel problems.
