Left the dock at 10AM. Air temp was about 30 Deg F. During initial run out engine ran normal but Tachometer display was jumping from 35 to 45+/-. The display would show 35, then instantly jump to 40, 45, then back to 35. Engine did not act or sound as any speed changes were actually occuring. Actual engine speed was approx 35(00) which was the bottom range of the erratic display. After running for about 20 minutes tach stopped erratic display and acted normal for the next 4 hours of running.
I'm getting ready to bring it to the boat doctor for its annual winter check up. I was just wondering what to expect to hear the issue may be.
Other than replacing the "cam, trim sender" this engine has been bullet proof for almost 10 year now.
