Winterizing your boat engine is a necessary chore if you want to enjoy your pleasure craft during the warm days of summer. Boats not only operate in the water but will often have water in the hull, gas lines and in some cases around the engine. This is normal because boating involves water.

Failure to winterize your boat can result in corrosion, cracked engine blocks, boasted hoses and cracked hulls. Repairing damage caused by winter weather can get extremely costly.

Preparing your boat from the grips of winter requires you to perform some basic maintenance in the fall of the year before the temperatures dip below the freezing mark.

Visible nicks and scratches should be painted to prevent corrosion and you should also change the engine oil and filter.

Some engines must be flushed with fresh water prior to storage. Be careful when performing this procedure because all water must be drained prior to winter storage because even a small amount of water can Yamaha boats engine for sale and cause damage to the engine.
