Winterising your outboard engine

Help your outboard engine survive the cold weather and next year you can enjoy a season of stress-free boating.

1. Fuel Conditioner...

Add Quicksilver Quickstor 355ml to the fuel to stabilise the fuel and prevent fuel breakdown and oxidisation for up to a year. Quickstor also prevents fuel system corrosion and gum build up, whilst also lubricating injectors and carburettors. 

2. Flush the engine...

Run the engine up to operating temperature with fresh water supplied from Flush Muffs, and flush away sand, silt and salt. 
 

3. Descale and remove salt deposits

Run the engine in a bucket or a flushing bag  and add descaling liquid to the cooling water and run up to normal temperature. 

4. Protective Coating...

Spray in Liqui Moly Marine Storage Fogging Oil  through the carburettors until the engine stops. This will leave a protective coating on the internal surfaces of the engine.

5. Engine Oil (4 strokes only)...

Change the engine oil (4-strokes only) using Quicksilver 4-Stroke Oil.

6. Spark Plugs

Remove spark plugs, injection nozzles or glow plugs and spray the Liqui Moly Marine Storage Fogging Oil  into the cylinder for 5 – 10 seconds (depending on the size of the cylinder). Turn the engine by hand or with a starter motor (without adding fuel). Refit the spark plugs, injection nozzles or glow plugs. The preservative does not need to be removed in order to restart the engine.

7. Waterproofing...

Spray the whole power head lightly with a water repellent oil such as WD40

8. Re-grease...

Clean off & re-grease the control linkages & grease points using Quicksilver 2-4-C Multi-Purpose Lubricant 

9. Gearbox...

Change the gearbox oil with Quicksilver Gear Lube.

10. Storage...

Store your engine vertically on an Outboard Trolley in a dry, well ventilated place ready for trouble free boating next spring!

Happy Boating!
