    Thank you Captain Ralph
    From one Bertram owner to another
    If you could confirm that I would appreciate it and I'm hearing various numbers on the horsepower if you possibly have some insight into that
    Thank you best regards

    You got it done yet?
    It's a feel and attitude for a good DDC 2 stroke tune up. Witnessed some techs knock it out in a couple of hours for both engines.
    Take me all day and then some.
