How Often Should I Do An Oil Chance On A Sea-Doo?

When you buy a Sea-Doo, manufacturers recommend that you do the first oil change once the engine has been ridden in or primed. That means that the engine has done a set number of hours without breakages and failures. On the Sea-Doo Spark, this is documented at 5 hours. For all other Sea-Doo models, it is set at 10 hours.

After this initial oil change, the recommended interval after that is at every 50 hours or at least 12 months for the Sea-Doo Spark. You can affect the oil change 50 hours after the initial 10 it took to prime the other models’ engines. You can do the following oil changes after every 100 hours. The newer Sea-Doo models can run longer between maintenance intervals due to more advanced engines, better lubricants, and parts.  

In every owner’s manual, you will receive an inspection checklist you need to follow to keep the warranty. Some maintenance inspection points need to be checked by the owner regularly. Some of the checks need to be done at an authorized dealer. Essential issues that you will need to check are;

  • The 5 or 10-hour Inspection – Dealer responsibility
  • Pre-Use Inspection – Owner 
  • Seasonal Inspection – Dealer and Owner 

Ask your Sea-Doo dealer if you are unsure of technical terms.

How Many Hours Does A Sea-Doo Engine Last?

The manufacturers state that a 2-Stroke Sea-Doo engine should last around 200 to 300 hoursTypically, a 2-stroke jet ski should be serviced once a year or every 100 hours. 

The Sea-Doo 4-stroke engine lasts around 300 to 500 hours and should be serviced every 100 hours.

These numbers are based on the average usage of around 30 hours per year. You can make your engine last by making sure you do maintenance when needed. Remember to follow a winterization oil change as part of the seasonal maintenance.

After the recommended number of hours have lapsed on your Sea-Doo, you can do a complete engine replacement. This should cost you approximately $ 500 to 600. 


Many variables can create the need to do a more urgent oil change than is recommended. Since your jet ski is in the water often, there is always a chance of oil getting into the system. This will cause the engine’s performance to become substandard, and if not seen to, it can damage your jet ski. 

Sea-Doo jet skis that are used in seawater conditions are more prone to corrosion issues arising. Always wash your jet ski after use and dry it properly before storing it away. In colder regions, you should never keep your jest ski without doing an oil change before-hand. If you follow the easy 23 step guide on doing an oil change for your Sea-Doo, your engine will be in the best condition and perform at its peak the next time you hit the water.
