    My motor is running very ruff.  It won't rev up very high in neutral.  I just changed the spark plugs and it's doing the same thing.  I checked the fuel pump and it's good.  I have new gas.  When I advance the linkage manually it surges then goes back down.  It keeps surging up and down.  Where should I start?  The boat was running great all day and on the way in it started acting up.

    Thanks

    Check compression.
    Check electrical system.
    Rebuild carb.
    Adjust linkages.
    Check entire fuel system for blockages, fuel line cracks or air leaks.

    At least, that'd be what I'd do. :-?

    Does anyone know an outboard mechanic with a good reputation I can take my 25 hp motor to fix in Miami?

    Thank you,
    Jose
