It seems that after running for a while I will start to loose RPMs and power, expecially if running over 3500 RPM. If there is any accessories on such as the bilge pump or blower and I turn these off the RPMs pick up for a few seconds and then come back down. The boat starts fine and normally runs great. I put a new battery in (measured 12.66V) and checked all connections. When I turn on all accessories and rev up to 1500 RPM I get about 14.4V measured at the battery. I also checked the alternator out while under load and it was putting out 14.7 However when I turn any accessories on or use my trim I notice that the voltage guage drop about 2 voltage points. Should I be looking for fuel problems instead? A new fuel filter was put in last year. This problem has been intermittent over the past 3 years.
