So I just purchased a 2000 sea doo gtx direct injection. I was riding it this weekend and the low oil signal came on, so I took it in to get oil. As i was driving up to ramp it started beeping and then shut off. I put oil in the ski and went to start it and it started giving me 4 beeps over and over then would turn and wouldn't fire. So I took it home and it started it in the front yard without water hooked up and it started fine, then when i hooked water up to it it wouldn't idle just shut off. Ended up putting new plugs and sea foamed it next day. Ran better so decided to water test it. Idled fine for a couple minutes then went to give it gas and it boughed out. Wouldn't start again so pulled it out of water and it was hard to start. finally started while out of water again. Pulled plugs looks like there may be water in engine any ideas? Also still getting 4 beeps and doesnt always turn when press start button.
