Took the boat out today...for the most part it ran well.
Then out of nowhere I get an alarm @~4000RPM, not constant, no rhythm. Could not tell which motor was generating the alarm. Can't be low oil....disconnected those wires and both tanks are >1/2 full.
Lowered to idle and alarm went away.....ran up to 4000 again......got an alarm again......did this a few times.
Returned to the dock......
Not over temp (not constant alarm), did not go to limp mode.....
Could it be a fuel problem?
Don't think it's too serious....at least I hope not, was still able to get to WOT!
