Closed coolant that is old or diluted will not protect a diesel that sits through a Jersey winter. Freeze protection at layup is a different job than summer overheating.

Some diesel work has to happen while the boat can still take water. Here is what to do the week before haul-out, including zincs and stray current.

A monthly start keeps a marine generator from sitting dead. It does not winterize the fuel, cooling, or impeller. Here is what the unit actually needs before it sits.
