      January 8, 2018 at 2:48 am 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

      January 8, 2018 at 6:12 pm 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.. Tony
