I have never had an issue with my engine from sitting during the winter, but I do very generously treat it with fogging oil. I am not sure about a diesel though, it might use the fogging oil for fuel ☹

In my case it resulted in stuck piston rings as indicated by low compression. Unbeknownst to me, the OEM suggests bagging the intake and plugging the exhaust. Instead, I have chosen what I think is a more conservative approach. I installed a 100w (120v) engine block heater to drive out the moisture, and to keep the air from being push/pulled I loosen the 4 bolts holding the exhaust goose neck. As for moisture in the cabin, the heat from the engine helps keep things from freezing and drives out the moisture to help keep things from getting mildew. In addition, I keep a household dehumidifier running full blast 24/7. Between the block heater and the dehumidifier the cabin is less than 40% humidity and usually better than 50°F. Keeping air flow is the other key to mildew and moisture management.

One is in the engine, I have seen boats who have plugged the exhaust pipe(s), and maybe even the intake inside the boat – And also in the cabin. I usually leave a hatch and something else on the other end of the boat open, so some air can circulate throughout the winter. Then I began to doubt the usefulness of this a couple weekends ago, when It hit 71 here, and was still 45 down in the cabin. I noticed lots of condensation below, which really bothers me. Does anyone know what the best solution is ? Bill Coleman Erie PA _______________________________________________ Thanks everyone for supporting this list with your contributions.
