3D 787 RFI Warning Light
Last year when I took the 3D out late in the year (new purchase - maiden voyage), I got a warning light and buzzer went off. I opened the hood and there was water in the hull, but well below the engine or intake. Total run time was less than 5 minutes. In the middle of the lake wondering what is going on is no fun . Towed it in at a crawl. Found the water inlet hose to the head came off. That's where the water came from.
I did all the normal engine checks (compression, etc.) and I am convinced that the engine is OK. Then I rode the ski for about 30 minutes and a dash warning light came on without a buzzer. Imediately went to dock and killed. I wasn't able to get it back out on the lake last year, but did winterize and ran the ski for a while out of the water and did not get a warning light at idle. It seems to take a while to throw the light.
I am not by any dealerships with a BUDS (and I am not sure that a light would even retain a code), so I am trying to troubleshoot before the season begins here. I have wondered about the temperature sensor (I know it was stressed), but it checked out using the maintenance manual procedure. I don't think it is the oil level warning, but not sure. Has anyone had a problem like this where they could share a few troubleshooting tips?

I looked at my manual some more and it references the following items that cause the check engine light with no buzzer:
- Manifold atmospheric pressure sensor fault
- Intake manifold temperature sensor fault
- Engine temperature functional problem (not sure what this is?)
- Engine temperature sensor fault (this is the one in the head I checked already, but who knows?)
- Sensor 5V power supply short to ground
- TPS out of range or short
Anyone else care to take a shot? Take a guess at what a engine temperature functional problem??

I am still having this problem, anyone have any ideas?
