Whats T.O.P.S.?
TOPS->Tip Over Protection Sensor.
low level oil can stop the engine and appears on display P1502?
or is a tops problem?
The Code P1502 is specifically for the TOPS system...
I can disregard that is low level oil that make the TOPS appears P1502?
I believe that is correct..
Love it. This makes you a great researcher.
The TOP switch in past post, has been reported as going bad sometimes. The shop manual for your ski should help find it. Usually next to the control board and relay switch.
As for the oil, it is best to use Sea Doo oil recommended. If you have a non supercharged engine, then a good motorcycle engine oil.
