05 GTX 4tech runs 40 mins

[lrcohiba]

Have an 05 gtx supercharged gtx and ran hard for 30 mins then died? Towed it back checked connections fired up for 5 mins then died. Took it back home changed plugs and added sea foam and have 85% of my tank with new fuel....need help I checked the pressure valve on fuel line and have fuel pressure coming out??? It sat for 2 seasons in the garage. I took it out next day and same thing 30-40 mins of good performance then it died. Got it back to beach and fired up and ran for 90 secs pushing throttle then slowly died like its starving gas?

Anyone have / had this issue??

That's a new one to me. Did you check the codes when it dies? When you run it, it dies, then you start it and it dies, leave the key on it put it into a diag cycle and see what codes it gives you. Let us know what they are if any to start with.

No codes I hit the mode like the book says and all I get is the END display and no codes to scroll with. Just topped it off again and it fired up throttled it till I got high temp and shut it off

I'm afraid it will do it again run for 30-40 mins in the water then die? It fired up as soon as I hit the start no motor turning over trying to get fuel just instant start.

When it died out in the water it wasn't instant it bogged like the gas was not getting there . I throttled and it slowly slugged into a stop.

Is your gas gauge reading the same each time? If it's 30 to 40 minutes each time it sounds like the gas tank is at a certain level each time it dies. I would fill it up and try running it for 20 minutes or so then fill it up again and run it and see if it dies in 20 minutes or let's you ride for the 30 to 40 again. Basically what you're trying to do is see at what level the tank is when it dies each time. I am betting it's the same level each time. It sounds to me like there is something going on in the tank. Did you ever drain the tank completely dry then refill with fresh fuel?

Read different first full then two bars less the next time. Have not drained tank ever. Dealer serviced except this year it was idle for two seasons just added sea foam to fresh tank and changed plugs tank was at 1 bar when added fuel this year

How do run motor and flush to keep it cool?

 

[Duane72]

You have to hook a hose to the output port for the exhaust cooling loop on the back of the craft. Should be in the manual on how to "flush" the cooling system after riding in saltwater, etc. Just make sure the motor is started BEFORE you turn the water on to flow through it. Also, even with the water running you should run it for no more than 5 minutes since the shaft/hull seal are not being cooled by water. Shut the water off BEFORE you shut the motor off.

Not sure on the stalling problem. With it quitting at different levels in the tank I'm at a loss other than the water in the tank possibility, sorry.

Thanks,
anyone else have this problem with motor shutting down after its running?
