    Default Mercury Saltwater 150 hp 2 stroke 6 cyl

    I have a mercury Saltwtarer 150 hp 2002 (2 stroke, 6 cyls, carb) and it heats up when running between 2000 RPM and 2800 RPM.
    When it is in neutral or runs over 3000 RPM it does not heat up.
    I changed the impeller, the thermostat, the water pump and all its components and the problem continues. Any suggestions? Tks.

    A "professional" is someone who gets paid for their work - it doesn't necessarily mean they are good at it :)
