      December 26, 2019 at 9:06 am Focus on the 52,000 plus hours of Marine Age, not the engine runnings hours at this stage. Complete seawater side servicing (not a descaler flush), engine coolant, and exterior appearances (paint touch-ups, corrosion protection, etc) wiring/harness connections point cleaning/lubing…..

      October 30, 2019 at 7:29 am That’s a maybe………………… For sure a Cummins tech can come down and reset the idle thru the ECM to 400-500-ish .. There may also be a a provision to add a control with a rocker switch at the helm to toggle it up and down..

    • Oil from breather

      This topic has 1 reply, has 2 voices, and was last updated byRob Schepis 5 years ago

      July 9, 2018 at 11:42 am Getting oil out of breather. 6BTA 330. Replaced turbo. Still getting oil. Ran another vent line. No oil. So it looks like the breather tube is plugged somewhere. Any ideas of how to clean the tube? Anything in the crankcase?
