How to Winterise a Jet Ski
If you are not planning on using your jet ski over the winter months then it is beneficial to winterise it before you put it away in storage or leave it outside on a versa-dock.
Below are the steps to take to winterise a Sea-Doo Jet Ski. We have also shown these steps on the video above or via our Jetski Safaris YouTube Channel.
Run your Jet ski with fresh water for 2 – 3 minutes. When the fresh water hose is disconnected the give Jet ski a couple of blips on the throttle to clear any water left in the Exhaust system.
Add Fuel Stabilizer. Check bottle and amount of fuel in the jet ski to get the right amount. If storing the jet ski outside, ideally leave it full of fuel and this will help prevent condensation build up in the tank.
Disconnect air intake pipe from throttle body. The method will vary dependent on tje type of Sea Doo Jetski.
Start up the jet ski and apply fogging oil into throttle body. Do this until the jet ski cuts out or has white smoke coming out the exhaust.
Remove Stick Coils and Spark Plugs.
Apply fogging oil into Cylinders. Squeeze for 2-3 seconds per cylinder.
Re-insert spark plugs and stick coil and reconnect.
Once refitted then squeeze the throttle and crank over the jetski a couple of times for a few seconds each time.
Disconnect the battery. If storing the jet ski outside to help preserve battery health you can remove it and put it somewhere where temperatures are not so extreme and drop below freezing.
Spray down the engine and components with anti-corrosive lubricant spray and remove any water from engine bay.
Run anti-freeze through the exhaust system. System shown in the video is a simple setup of a bilge pump powered by an external battery.

A couple of extra helpful tips:
Remember if you are planning on storing your jet ski in an alternative place to it’s usual summer storage location, check with your insurer that it is still covered in it’s new location.
Leave the seat ajar throughout winter storage to help air circulate through the jet ski.
Invaluable tips from our resident RYA PWC Trainer Ross Ceaton relevant if you are taking your Jet Ski Instructor Course at a land based RYA Training Centre or are Superyacht Crew, and have a RYA PWC Trainer running a course onboard.
Here at Jetski Safaris we often get asked by customer’s with their own jet skis whether it is possible to carry on riding through the winter. The quick answer is yes. Whilst we don’t offer our Jetski Safari experiences through the winter months we do carry on with our RYA Personal Watercraft Training Courses all year round.
With Jet Ski’s being such a big investment for a seasonal piece of sports equipment, it is important that you give them attention every time you use them. Regular maintenance should be applied throughout the season and not just at the start or end.
