What’s included and why these parts matter?

The kit bundles the oil, filter and sealing components you need for a complete oil change — no scavenging for separate parts. Using the OEM oil and filter helps ensure fit, filtration and lubricant compatibility with Sea-Doo engine tolerances and seals.

• XPS 5W-40 full synthetic oil matched to Sea-Doo requirements
• Manufacturer genuine oil filter sized for proper flow and capture
• New o-rings to prevent leaks at service interfaces
• Washer for the drain bolt to ensure a reliable seal

How do I perform the oil change with this kit?

Performing the oil change follows standard procedures: warm the engine, drain old oil, replace the filter and seals, and refill to the correct level with the supplied synthetic oil. Always follow Sea-Doo’s service manual for torque specs and disposal of used fluids.

• Warm engine, then shut off and access oil drain
• Remove old oil and filter; replace o-rings and washer
• Install new OEM filter and torque drain bolt to spec
• Refill with XPS 5W-40 full synthetic to recommended level

Why choose an OEM kit instead of aftermarket parts?

An OEM kit ensures each component is specified for Sea-Doo engines and helps maintain original performance characteristics. Genuine parts reduce the risk of fitment issues and support consistent oiling and sealing compared with unknown aftermarket components.

• Parts designed to Sea-Doo tolerance and material standards
• Simplified ordering — one SKU contains all needed items
• Helps maintain service history with factory components
• Reduces time and errors when preparing for a DIY service

If your model calls for 5W-40 full synthetic oil and accepts OEM Sea-Doo service parts, this kit gives the correct lubricant, filter and sealing hardware in a single purchase to streamline routine maintenance and help preserve engine reliability.
