    Default Ford Lehman 120 won't exceed 1500rpm when in gear

    Hello, I recently changed oil and replace an old valve on fuel tank that was sucking air. Boat has been setting for two months and just set out from Marina. When in gear the port engine will exceed 1500rpm but it will rev up at in neutral. Any suggestions? Jim

    Hi jim, sounds like fuel filters or stop solenoid over adjusted, not allowing fuel rack to move to full fuel.

    Now I have found no fuel or air coming out of the fuel return line and excessive fuel consumption. Filters have been changed.

    Hi jeccost, return line only sends about a cup of fuel back to the tank in an hour. Check your engine oil for fuel dilution==possibly bad lift pump.
