Should a boat motor be up or down for winter storage?

As winter approaches, many boat owners have to face the task of preparing their boats for the cold winter months. Winter storage is an essential practice to ensure the longevity and preservation of your boat. One critical aspect of winterizing your vessel is the position of the boat motor.? This question has been a subject of debate among boat owners, but here’s what you need to know.

In general, it’s best to store your boat motor in the upright position for the winter. When the motor is up, it prevents water from sitting in or around the engine. Water can freeze and cause significant damage to the engine block, corrode the metal, or clog the cooling system. Moreover, the upright position allows for proper drainage of any remaining water in the engine. Therefore, it’s essential to flush your motor with fresh water to remove all traces of saltwater before storage. By positioning the motor up, you can prevent any leftover water from settling in the lower parts of the engine.

On the other hand, some boaters prefer to store their motor in the down position because it relieves the pressure on the power trim system and reduces the risk of seal damage. However, this position increases the likelihood of water entering the motor and not draining correctly. Besides, if the seal on the power trim system fails, the motor will lower, and the boat’s weight will compress the seal further, leading to more extensive damage and costly repairs. While lowering the motor seems like the easy choice, the potential consequences outweigh the benefits.

The safest and best option for storing your boat motor in the winter is to position it up. This way, you can avoid any water buildup and ensure proper drainage. However, before storing your motor, it’s recommended that you follow the manufacturer’s guide on winterization. Also, don’t forget to use antifreeze, fogging oil, and fuel stabilizer to keep your engine components in good condition. Finally, cover the motor with a well-ventilated cover to protect it from the winter elements. With these precautions, you can ensure that your motor is ready to go in the spring when the boating season resumes.
