A common issue with 2 stroke Sea doo watercraft is missing or brittle oil line’s.
Check oil Line’s every season or replace.
All older Sea-Doo 2 stroke Watercraft need to have the oil line’s inspected every year. Better would be to replace the old line’s. After a few yers of use the oil line becomes brittle and fails. Unfortunately most do not catch the issue until oil is leaking into the hull under the engine.
