      April 4, 2023 at 10:50 am I just had my boat pulled for bottom paint and the starboard prop nuts have backed out to the pin. Ā This has happened every time Iā€™ve had the boat pulled over the past 10 years even when the mechs are advised and try to torque it hard. Ā What could be used this time to get the nuts to stay in place? Ā FWIW the shafts are 2ā€ and the props are CJR nibral. Thanks

That might have been the reason one of the 8D’s over temped. Thanks, Steve

      July 2, 2018 at 12:02 pm Cummins 6CTA Came back from a long trip (2 months/1100 miles) and all engine systems were to spec. Shortly after getting back I changed the fuel filters and cleaned the air filters. I also did some interior work that may have affected my turbocater boost lines. Last week we took the boat out and she came up on plane fine and spooled up to 2650 RPM. However I noticed that the starboard motor boost lagged and only came up to around 10 PSI at WO…
