    Not able to achieve recommended wot rpm ?

    I can't make this a sticky cause i have zero powers to do so.

    Here is the list, lost forever due to the changeover.

    Thanks to the boating g-d's i had posted the list on other boating sites.

    List of possible causes of low WOT (Wide Open Throttle) rpm.

    In no particular order

    Engine Won't Reach Operating RPM. Check

    1. Fuel condition. Type and Octane possibly old fuel
    2. Propeller pitch or diameter, damaged blades
    3. Restricted fuel pickup tube or anti siphon valve Fuel System Test
    4. Crankcase oil volume, high oil level can cause aerated oil and lifter collapse
    5. Marine growth on hull and outdrive
    6. Wrong gear ratio in outdrive
    7. Restricted carburetor air intake (clogged flame arrestor)
    8. Restricted exhaust system (broken exhaust shutters/flappers) in engine transom shield or drive
    9. Poor cylinder compression Compression Test
    10. Carburetor defective, or wrong type.
    11. Fuel pump pressure and vacuum
    12. Boat overloaded, improperly loaded, or improperly trimmed.
    13. Engine Overheating
    14. Engine timing and ignition system operation
    15. Remote control cables and linkage for proper travel to open throttle plates fully.
    16- Hidden water in the hull.

    In the case of a diesel it maybe low air boost from the turbo.

      A little corrosion on the cap and rotor contacts can cause WOT to gradually decrease over time.
