Recognizing that many readers are in warmer climes or have boats that don’t need special winter preparation, we present this for those not so fortunate. Torresen Marine will have more than 600 boats in storage for the winter months. Most of these boats require special care to prevent damage from freezing water. Our standard winterizing covers some or all of what is listed below. If you do the job yourself or have it done elsewhere, this checklist will help to know what needs doing and what results to expect. Always keep in mind that the only freeze damage you can expect is the result of freezing water. (more…)

Winterizing Sea Water Cooled Inboard Engines
This is to give general guidelines for the winterization of inboard engines that do not have internal heat exchanger type cooling systems. Variations will become evident in different brands of engines, however the principals will be the same. Engines do not freeze. It is the water within the engine and peripheral equipment that freezes and causes damage. To preclude freeze damage you must either eliminate the water or make it so that the water will not freeze.

It is highly recommended that if the lube oil needs to be changed that it be done prior to lay-up so that fresh oil is coating the innards of the engine. If fuel filters are in the plan do them first. Then start the engine to check the fuel filters and warm the engine to facilitate the oil change.

If you are in an area where you need to winterize the systems on your boat, it is important that you select the proper antifreeze. For the internal water on your fresh-water-cooled engine, use ethylene glycol. This comes in many brands and has additives to reduce corrosion, lubricate pumps and enhance heat transfer, among other things.For everything else, including the seawater side of your fresh-water-cooled engine or the complete winterization of a sea-water-cooled engine, use propylene glycol (RV-MARINE) – usually pink.
