The trouble with engine condensation and keeping a boat in the water is that the wet muffler creates a loop seal and will push/pull moist air through the engine cylinders. 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.
