    2010 255hp Speedster max speed issues??

    Hey everyone, just took delivery of a brand new 255hp 150 Speedster 2 months ago.

    So far the boat has 16 hours on the clock but is yet to reach its full potential I don't think.

    Just some stats so far:

    • 16 hours
    • Max Speed 80km/h (49.7mph) in calm water (1/4 tank fuel, 1 x 70kg passenger, no additional weight)
    • Generally boating in choppy water
    • Boat HAS undergone first 10 hour service.

    Can anyone explain to me why Im not getting more power and speed out of the boat? Is it just the engine isnt fully run in yet? What do I need to do.

    Thanks,
    Dan, Australia

    Also, make sure you're using a GPS to gauge your speed. My speedo registered -16% under actual (-10mph at top speed), until I fixed it.

    49mph seems very low... +1 on the RPM's.

    If the oil was over filled you will loose rpms. make sure your oil level is in the center of the bump on the stick and not at the top of it. Run the engine for 30 seconds, shut it off then count to 30 and check.

    Hey everyone I'll get onto the RPM's asap, as soon as I get the rear hood to close!!
