Remove the oil filter cover and old oil filter with the E-8 external torx driver. On most models, there’s just one bolt — but the Sea-Doo Spark PWC comes with three bolts to remove. Be careful not to drop them into the hull. Set the bolt(s) aside and remove the old O-ring(s).
NOTE: 900 ACE engines will have just one O-ring. The 1630 ACE engines will have two O-rings you’ll need to replace.
Carefully remove the old oil filter. You’ll want a rag to catch any drips. Wipe the filter cover clean and inspect the oil filter housing for any debris and clean if needed.
