"The Starboard engine will run
"The Starboard engine will run fine at 3000 RPM for about 20-30 min. then it will loose RPM/power and I can only maintain 1800-2100 RPM's. If I add throttle it will spudder and miss and the RPM will drop off untill I reduce the throttle. If I run it at the lower RPM for a while 20-30 min. it will take throttle again (maybe). The next time out it might not do it at all with 3 hrs of running, then next time do it. Port engine runs fine.
I have replaced fuel filters, checked tank for water, replaced carb. replaced fuel pump, ran off port tank.
Fuel problem? maybe vapor lock? ignition? this is very baffling. Any thought, something I am missing? Thanks"
