05 Rxt oil sensor goes off at 4,000rpm.

[ADAM12]

I recently replaced all 3 oil sensors and pump. Ski idles fine on the water but at 4,000 rpm the ski bogs and oil sensor goes off. I rebuilt the engine since my sc decided to go out on me. What can be causing the problem?

You need to check your oil pressure. Install a guage on the fitting at the rear of the head (1/4 npt fitting).
You replaced your oil pump but did you replace the pressure relief valve.

First thing is to be sure your oil pressure is ok.

Cold it should be ~80 psi at idle and any rpm
Warmed up, ~20-25 psi at idle and around 40 psi over 3000 rpm.

My 06 RXT doing same thing. Dealer replaced motor over the winter due to supercharger failure. Got it back, right at 3500rpm oil light, code 1520, limp mode. They replaced a sensor last week, still doing it. Ski is at the dealer now, will let you know if they ever figure it out.

Out of town right now so I will get on it once I get back. Let me know what the dealer found out.

oil pressure switch is the problem i changed mine no more limp mode

.

yes, pressure relief valve and oil pressure switch where replace. I can't wait to get home to start working on it.

[bigdeez]

did they replace both pumps? make sure your oil levels are correct.

Any word from the dealer. Just got back.

Talked to them 06/18, they said they talked to Seadoo and they thought it was a wiring problem. Called today 06/23, they still dont have a clue. It looks like I may have to get Seadoo involved again (not that It got me anywhere last time).

What up guys,
Here is the dealer story now. They are telling me that the valve seat sleeve on the oil pump could be damaged do to over thightening. They said they are 95% sure that is the problem since one of the mechanics had the same issue on another ski. Let me also mention they replaced all the sensors over again just in case. I also asked what the oil pressure reading was and they did not check it. This does not sound right to me! If my oil pressure was ok would it be giving me this problem? They did not rebuild the engine originally. So they said they need to pull the engine out to get to the oil pump. What should I do?
