How Do I Winterize My Motor ?

  • Winterizing an outboard motor is a critical maintenance procedure that should not be overlooked.
  • If done correctly, it could save you money on spring replacements and extend the life of your engine. This article will take you step by step through the process of winterizing an outboard motor.

Preparation 

  • First, take the boat out of the water and thoroughly rinse it with fresh water to remove any salt or dirt.
  • Remove the outboard motor from the boat and secure it to a solid surface. 
  • Gather all of the required materials, such as a fuel stabilizer, fogging oil, gear oil, and or a water pump repair kit.

Step-by-Step Winterization 

1. Replacing oil

  • Change gear oil in the lower unit. 
  • Replace the engine's oil. 

2. Fuel System Stabilization & Optimization 

  • As directed on the label, add stabilizer to the fuel. Use fresh water to completely flush the cooling passageways. To move the stabilized gasoline through the system, run the engine in neutral at about 1500 rpm for five minutes. Then, 
  • Shut off the engine then turn the water off. Turn the fuel cock lever off, turn it to the right. Disconnect the fuel line and cap the engine connector if you're using a separate fuel tank. 

3. Engine Lubrication (Carbureted & EFI)

(Carbureted)

  • Take off the carburetor intake's air silencer or lid.
  • When the engine is operating at a fast idle speed (roughly 1,200 to 1,500 rpm), spray the carburetor throat with fogging oil.
  • It's typical for the engine to start smoking. Continue spraying until the engine stops.
  • After a strong dose, manually shut it down if it doesn't stall.
  • Lubricate all other specific parts according to your owners manual. Use a rust preventive (not penetrating oil) such as a fogging spray/oil on the powerhead surface. Do not soak belts, rubber hoses, or electrical connections just a light coat on metal.
  • Use fresh water to clean the outside. 

(EFI/4-Stroke Fuel Injected Outboards)

  • Use the same warm-up procedure.
  • After turning off the system, take out the spark plugs.
  • Fill each cylinder with a generous amount of fogging oil.
  • To disperse the oil inside the cylinders, turn the engine over by hand (or briefly with the starter, ignition disabled).
  • Put the spark plugs back in.
  • Use fresh water to clean the outside. 

4. Engine Storage

  • Wipe it dry. If you're using a pressure washer, keep the nozzle far away from the engine. 
  • Store upright in a dry, ventilated area with steady temperature; keep away from heaters/furnaces.

Checklist for After Storage

To restore your motor to operational condition after removing it from storage, follow these steps:

  • Make sure the spark plugs are clean. If required, swap them out.
  • If necessary, apply gear oil using the method described in the Gear Oil section after checking the gear-case oil level.
  • All moving parts should be lubricated in accordance with the Lubrication section.
  • Verify the level of engine oil.
  • Wax the painted surfaces and give the motor a thorough cleaning.

 Why Do I Winterize My Motor?

Winterizing your Suzuki outboard is an investment in the long-term health and dependability of your engine, not merely a yearly task.  You can prolong the life of your outboard, prevent expensive repairs, and ensure smooth starts by following these factory-approved procedures in the fall and doing the fast checks when you put your motor back into operation in the spring.

 Consistency is crucial, whether you want to arrange a professional service or manage the process yourself with the appropriate supplies.  When boating season returns, your outboard will take care of you if you take care of it during the off-season.

(To ensure the longevity of your motor, always follow the manufacturer's instructions and use high-quality materials.)
