Outboard Winterization

Outboard winterization is an important process that helps to protect your boat's motor during the winter months when it is not in use. This process involves draining the engine's cooling system, fuel system, and lubrication system of any water or fuel that may have accumulated during use. It also involves adding a fuel stabilizer to the fuel tank to prevent the fuel from breaking down and causing damage to the engine.

One of the main reasons why outboard winterization is so important is because water can freeze inside the engine and cause damage to the internal components. When water freezes, it expands and can crack engine blocks, manifolds, and other critical components. By properly winterizing your outboard motor, you can prevent this from happening and ensure that your motor is ready to go when you are ready to hit the water again in the spring! Our team at Lighthouse Motorsports & Marine can assist you with your outboard winterization needs.

Jet Ski Winterization

Your personal watercraft needs to be winterized, too – and the end of boating season is a good opportunity to change the oil. Our mechanics can get your PWC prepared for winter storage, so it will be ready for next season.

  • Basic Jet Ski Winterization: $175
  • Jet Ski Winterization with Oil Change: $275  - includes filter and 4 quarts of mineral oil. Additional fees for synthetic oil and/or additional quarts needed. 

Dewinterization

When boating season comes back around, a “spring run-up” will prepare your boat for action. This process confirms that the engine and the electrical systems are all in good working order, and it is required to guarantee the warranty on your boat.

  • Spring Run-Up: $149

Please note that any of the services listed above will include additional charges for synthetic oil or services after the first freeze. Please contact us with any questions!
