240 EFI 04 seadoo challenger 2000 - need some direction.

[spideyred]

Some background....about a year ago the oil level was low and the alarm went off. Filled oil tank with new oil and it seemed to fix the problem. Then had a few friends over and my son was not watching the tow rope and it got sucked up. I pulled to boat out of the water and took care of the rope.

Since then the 4 beeps every 2 minutes has been going off.
It won't reset. Oil level is good. Oil reservoir is good as well.
I checked the fuel water separator no water.

If I throttle full the engine sputters and coughs and the solid alarm comes on until I put it back in neutral.
I can gradually get the boat up to about 15 mph but any faster and the solid alarm comes on or engine begins to sputter again.

I have a friend that is a car mechanic and we have tried to research this problem. We think it is the fuel injectors.
I have replaced all of the spark plugs and some junk did come out when I turned it over without the plugs in.
I currently am running a can of seafoam through with new gas. I pumped 12 gallons of OLD gas out of the tank.

I need some help determining if it is the injectors. And if so...where can I find the diagram of the engine and injectors to have me and my friend do this ourselves.

Thanks

The intermittent beeping is either water in the fuel, or Low oil. I would verify both.

The low oil should also trip a limited power situation. SO... that's probably the reason it won't rev up.

The beeping I had with my challenger this year sounded like a truck backing to a loading dock.... about a beep a second with the oil light on. When I checked my water separator I had some water. I dumped it and replaced the filter and the beeping and lit up oil light went away.

When I had water in the fuel it sputtered to a stall. After the fuel was pumped out and refilled it has run well.

oil level is good.
I will replace the water separator and see what happens before I look into the fuel injectors.

Spideyred, where in Florida are you? We are in Lakeland and have a 2001 Challenger 2000 with the Merc engine.

JG:

I started having the same problem a few weeks ago with 240 EFI in my 2004 Islandia. Were you able to figure out the cause of problem.

"If I throttle full the engine sputters and coughs and the solid alarm comes on until I put it back in neutral.
