The de-winterizing procedure is when you make sure your equipment is ready for the new season. Before starting the engine, we highly recommend following these steps to see if any problem comes up along the way. Also, we encourage you to do your own research in more depth if you encounter any issues that need more detailed investigation or, better yet, get it to the service center. The information written here should serve as a starting point, but hopefully the ending too. For now, get yourself a nice rag, and let’s jump straight into it. Your jet ski spent a fair amount of time in storage, so it needs to be properly inspected. During the process, check for the following things: If you still have your vessel manual flying somewhere around, this is when it will become handy. Read it and see if your manufacturer provides any specific directions for your water sports equipment. Once you finish skimming it, take a look at the additional tips we provide down below. We suggest following them in the order of their mention. If you had not replaced your oil filter when you were winterizing the equipment, we suggest doing it now. When replacing the oil filter, it is critical to make sure that the oil line lacks air bubbles. Bubbles may have a harmless effect if they pass through the small injection lines. However, if there is a big one at the pump, this is when you want to investigate further. It is because you can lose prime and can cause your jet ski to fail. The manipulations with the oil filter should help trap the air out, causing the issue. If it does not, we suggest talking to the mechanic. Just like you would add the antifreeze when prepping your equipment for the winter storage, this is when you want to make sure that you remove the residuals. Take a look at the video below on how to exhaust flush it for Sea-Doo:
If you did not take out the battery during the winter and left it inside your WaveRunner, it likely became out of charge during hibernation. If that is the case, do not charge it inside the equipment, as it might be why your jet ski won’t start. Inspecting it for corrosion should also be considered part of daily maintenance to keep it lasting for years, not only after winter storage. Give your battery a full charge. For lead-acid wet battery type, ensure that water levels are appropriate. With the help of a battery tester, check the amps and volts. If it is charged and you still got no luck, this might indicate a need for a new one. When you were winterizing your jet ski, you likely pulled hull plugs for trapping water out. What you want to do now is to reinsert them so that your equipment does not sink. To check the conditions of spark plugs, first, clear out the fogging oil and flush them. If you notice that either of your plugs are not in their best condition, it is time to replace them to avoid leakages and sinking. As a rule of thumb, it is always good to start a new rental season with a new pair of plugs anyway. Just make sure you’ve got the right PWC plugs matching your WaveRunner engine. If you are located in freezing climates, it was a good idea to drain the cooling lines for winterization. Also, this is another part of your jet ski that should be treated with a flush of running water. Ensure the exhaust is fully clear to avoid engine problems (e.g., overheating). To get the proper free rotation throughout the season, you will want to grease the driveshaft. Also, if you operate in ocean waters, this will help ensure that your drive shaft does not get rust. If you ride saltwater, we recommend removing the impeller and antiseize the prop shaft. Once you are done checking on jet ski conditions, you must give it a thorough washing and cleaning. While there are no specific guidelines for doing it after winterization vs. any other times, it would not hurt to shine your WaveRunner up after each use. The video down below shows the step-by-step approach for deep washing:
Notice that video authors split the process into the following steps: 1) Rinse Jet Ski 2) Rinse Trailer 3) Wash Jet Ski 4) Rinse Jet Ski Engine Bay 5) Drain Jet Ski Hull 6) Flush Jet Ski Engine 7) Jet Ski Rust Protection 8) Correct Jet Ski Storage Just like you’d help your customer with it, see if it is ready for renting by checking the engine. You should take it as one of the final indications for the equipment readiness for a new season. If they did not start, see if our separate guide to help with jet ski starting issues can solve the problem before taking them to the mechanic. Some of the other final small things that we suggest referring to as your final checklist consists of the following: As we have already mentioned, this guide should serve as a starting point only.
