Please help! My engine initially seems to run great. However running at length(sometimes after 10 minutes, sometimes 2 hours or so) it will completely fall off plane and run what seems to be at 50% power. Sometimes it seems I can throw it in neutral and rev her at high rpm, than when put back in gear sometimes will plane back for a bit, but for the most part I cant trust it in the ocean. I have had all new fuel lines, bulb, water seperator replaced and checked. I have all new coil wires, new plugs and spark wires, pretty much everthing replaced by a professional. Compression is 125lb per cylinder, too. I just cant iron this quirk out. In addition it NEVER dies, just runs at a crawl, but fine at low speed. Could this be a power head? My voltage gauge also runs below what it should be and my mechanic suggested that may be the problem, and the water pump also seems to POSSIBLY not eject as much water as i might expect, but the motor never seems to get hot. Anybody ever hear of such a thing?
