While I was planing, I all of the sudden lost power and can only go maybe 5 to 10mph. Anyone know what could cause this? I just replaced my stator flywheel, power packs, plugs, fuel lines, inline filter, and water separator. Motor doesn't over heat. I'm suspecting something in the lower unit like the water pump/impellar and hub in propeller or fuel issue such as the carbs. Also maybe poor compression? When I flushed the motor and put it in gear rpm seemed to rise properly. Any one have any ideas what to do?
