After running the boat on the water for about an hour pulling tube riders with no problem, I started the engines after trading out riders and the "Check Engine" warning popped up and alarm sounded. This occurred at the same time as the Low Fuel indicator came on as well. I headed to the marina to fill up and the boat ran fine, but the check engine warning still flashed. After refueling and running the boat for another half hour or so, the warning finally went off. The owners manual says it is a "Faulty Sensor." Has anyone experienced this or have any suggestions?

Checked your oil? Or Could have been an overtemp warning?

I wonder if some impurities in the bottom of the fuel tank might have caused the engine to stumble a little and triggered the CEL?

I checked oil levels before we headed out and both were fine. Water was flowing from both outlets and nothing indicated that it was a temp issue.

Should be easy to repair. The computer caught the offending sensor and has it stored. Find someone with the YDS and bring it up. I personally would just replace the sensor unless you suspect something mechanical caused the problem. (such as a wire harness not fully connected)

Could it have been flashing a code? or do the newer models display the code directly?

Issues when pulling tubes seem to center around overheating. If you don't think it is related to temperature, I would probably leave it as is and see if you have any issues moving forward.

@Gym, the tach displayed a flashing message "Check Engine," and the alarm or beep sounded. I had to keep silencing it. After about a half hour, everything went back to normal.

The newer boats have a diagnostic function on the muti function gauge. Mine (a 2010 with 1.8 liter engines) does anyway. I've never used it but have scrolled past it several times. You may be able to get more detail or the history of the warning there.

I have an 06 waverunner with a 160 hp mr1 engine that threw a warning about 30 mins into the day a few weeks ago. After recharging the battery (which hadn't been maintained in a few weeks) the warning finally turned off. Could it be that your battery may have been a little low when you started but charged to the appropriate level a few hours into the day?

I have seen the low fuel warning in my boat, it was not accompanied by any other warnings, just a " low fuel" readout on the multifunction gauge's display. As I recall when the overheat warning comes on I get both a visual and audible warning (my over heat warning has come on after I've gotten vegetation stuck in the pump). In those instances where I didn't have to manually clear the obstruction because it fell out on its own (e.g. After doing the reverse move to clear the intake grate) the warning would stop on its own on the next startup.

@buckbuck, what is the "YDS"?

I'd like to point out that this happened to me this weekend. It happened after I had gotten stuck on a sandbar next to a jetty. I had no signs of overheating and oil levels were fine. I ran the boat back to the ramp and pulled it out. Checked the screen on the cooling intake, no issues, water was flowing from the pee holes. Put it back in and ran it 15 mins back to the dock, let it idle for 10 minutes and the check engine light no longer comes on and everything seems normal with the engine.

No idea what happened...

On a side-note about running on one engine...

I have tow valves installed and tried to run back on one engine, needless to say with me and one other person on board I was nowhere near planing speed with the starboard engine at full throttle and the pump had a ton of cavitation. I promptly halted that attempt, opened the tow valve back up and ran both engines again.

I know have a different boat, but I had a Check Engine message for a few days (!) last week. I took it in to have the code read, and it turned out to be a low battery warning.

The worst part was that I had it on the charger and had a fully charged battery and the message still popped up. Then as I was going to the ramp to pull it out, it disappeared. Apparently it took ~1 day for the fault to clear. Annoying.

I was back on the water yesterday for the first time since getting the Check Engine warning. I ran for about two hours with out any issues. I've read about a lot of funny things happening due to a low battery, so I'm going to blame it in that.

The only thing that is associated with the CHECK ENGINE ALARM is faulty or bad sensor according to the owners manual. Every other alarm is specified by what the problem is.

I had an overheat alarm after I ran over a weed bed pulling up to my slip. Next time out when I started the engine the check engine light and alarm went off. Shut the engine off, waited a minute, and restarted, all was well from there on out.

I had a similar issue backing out of my slip this summer. Started the engines and the port side had an oil pressure warning light on. It's never been on before. I shut it down. Waited a few moments and fired it back up and it's been fine since.
