Summer’s definitely waved its final farewell to the UK this year, so you really need to get your jet ski ready for the cold season. Here at 1 58 Performance you can take advantage of our special ‘Winterise and Service’ offer for just £200 – how’s that for a great deal?

Getting a jet ski ready to go the following summer is the most important part of winterising this personal water craft. To insure the jet ski runs properly, check the fuel, oil and engine in the fall. Prepare the jet ski as soon as the weather warms.

Difficulty: Moderate

Instructions

1. Drain the water from the jet ski right after it’s taken out of the water for the final time. When on a trailer, the jet ski is usually tilted back. Run the engine several times for no more than 30 seconds each time. Tilt the handle-back and-forth while it’s running to drain the water from the engine.
2. Use mild soap and water to scrub the exterior of the jet ski. Wash away all algae, water stains and grime from the sides, seat and back. Make sure there is no water left in the hull of the jet ski when cleaning. Use a normal wax on the exterior to give it an added protective coat and shine.
3. Fill the gas tank to the top before storing for the winter. Add stabiliser according to the directions on the bottle to keep the gas clean for the next season. Run the engine in 30-second intervals several times to get the stabiliser mixed through the fuel before storing.
4. Remove the air filter to allow easy access to the carburetor. Spray fogging oil in the carburetors and spark plug cylinders. Spray the oil while the engine is idling. Continue spraying until the engine stalls and replace the air filter.
5. Take out the spark plugs. Make sure the wires are grounded first. Spray fogging oil into each spark plug hole. Put a rag over each hole and push the start button to disperse the oil. The engine will not start because there aren’t spark plugs in place. Replace the plugs and clean up any excess oil.
6. Remove the battery, negative connection first, followed by the positive connection. Store the battery in a warm, clean area.
7. Trailer tires can rot in winter months if they are stored on dirt or gravel. Cover them with plastic bags and put them on boards. To keep them from rotting, take them off the jet ski and prop the trailer on blocks.
8. Store the jet ski on the trailer with wheels off for best wheel maintenance. Place steel wool in the exhaust to prevent animals from getting in the engine. Cover and store the jet ski for the winter.

That’s all there is to it. Simples, eh? Okay, it’s not that easy; there’s no shame in getting us to do it for you and our £200 winterise and service offer still stands
