The boat has around 600 hours on it. This weekend I was driving at 40 mph for about 10 minutes when the engine went dead. All the gauges were within normal range. I checked both the fuel cell and fuel rail by depressing the valves. Gas was present. Still would not start (engine would crank). I checked all the breakers and knocked on the two relays under the engine by the 3 breakers. None appeared to have been popped. About 5 minutes into my tow home, I was able to restart the engine. The water was calm and the stereo was on and loud at the time (not that it should matter). Any ideas?

If your sure its not fuel then it theoretically should be a spark issue. -
RE: 01 Air Nautique Died Suddenly
Thats what I am thinking. I have a buddy that has a Tige with the merc engine. He carries relays that he has to replace almost yearly. I don't think PCM has the same issue.sigpicComment

Sorry to hear about your boat.
I was looking at your screen name and where you live. Do you go to/have a place at Echo Lodge? I'm asking because that's where out place is...UL13.

At least someone is running by my place. I'm typically riding in the morning...only time we can get good water.Originally posted by EchoLodge
We'll need to hook up next time we're both down there at the same time.
See you soon.

Start Hydrofoiling... Then you can ski in the bad water too!

Do this primary ignition system test:

Do this fuel pressure test:

That should narrow down your engine problems a lot.Comment

Thanks. Do the relays below the breakers in the second picture of the fuel pressure link control the fuel pump?Originally posted by DanielCsigpicComment

One of the relays supplies power to the ignition system, the engine's computer, and the coil of the fuel pump relay. The other relay supplies power to the two fuel pumps.
Both of the "cube" or "Bosch" relays have power applied at pin 30 of each relay, all the time the battery is connected.
The key applies power to the ignition/computer relay coil at pin 86 and the coil is always grounded through pin 85.
Power is then applied to pin 86 of the fuel pump relay. When the engine computer decides it needs to turn the fuel pumps on, the computer grounds pin 85, turning the fuel pumps on.
You can download the GT-40 diagnostic manual from the download section of this site.Comment

Did you check your lanyard? That got me once after my buddy towed me in and we were on the trailer noticed it was not fully engaged.Comment

Another good thing to check. I was able to get it restarted w/o messing with it. It was a hot day and the boat was running close to wot for 15 mins. With the engine cover up and me messing with everything I could think of I am wondering if the relays cooled and came back to life.Originally posted by QuinnersigpicComment
