    Hi Everyone
    we have launched a new 53 ft boat with twin 464 , 6 cylinder commercial duty Yanmar diesel engines
    The engines are meant to have a maximum rpm of 2700 when at full speed. Unfortunately , they only go up to 2200 RPM ( Its not the propellers , since even with engines out of gear , engines dont exceed 2200 RPM)

    Any tips as to possible causes for this problem ?

    Thanks beforehand

    G

    Tell us what the EXACT model of the engine.. 464 HP tells me nothing.. Better yet, maybe a very clear and in-focus picture of the data tag..

    Have you eliminated improper throttle cable linkage setup as the cause? disconnect and control at the inj. pump?

    So this is a NEW install? 1st run? This is the CX series, correct?
