Your Marine Diesel Winterizing Routine

Published on October 12th, 2023

Winterizing our boats at Scuttlebutt HQ means we have to do, uh, nothing. For everyone else not located in San Diego, Darrell Nicholson provides the marine diesel winterizing routine in Practical Sailor:

Winterizing an inboard engine installation means a lot more than filling the cooling system with antifreeze and stuffing a rag in the exhaust outlet. It means taking care of the exhaust system, the fuel system, the engine controls, and other components of the drive train, such as the shaft and prop. If you want to do these things yourself — none of them is difficult, only time consuming — plan on a long day of work, or perhaps a leisurely weekend.

It’s work that will pay off, however, both in im­proved understanding of your boat’s propulsion sys­tem, and in money saved. At $25 per hour, the simple projects described here will save you about $200. Few special tools are required, and the only skill necessary is a modicum of common sense. – Full report
