xp 650 running problems

[shane93]

i brought a seadoo xp 650, it was running fine on the trailer but when i put it in the water it wouldnt start, so i done a compression test and had low compression, i changed the pistons and rings and all topend gaskets, i also stripped the carbs and checked and cleaned them, the little filters were really blocked, ive also changed the main fuel line and took petrol out and cleaned and refilled with new fuel. Thinking it would be good to go i took to the water and it started fine, i left it running on the water to gently run it in, then when i rode it, it felt good and pulled well but after 15 minutes it cut out and wouldnt start, so i took it home put new plugs in, i then took it out the next day and it ran for 15 minutes and cut out, when it cuts out it sounds like its firing but will not start even on the trailer. thanks in advance for replys hope someone can help

did you replace all the fuel lines?

The gray lines are trouble, and the carb filters, and the fuel select valve can be plugged up again.

thanks for reply, i have just changed the rest of the fuels lines and cleaned the selector valve, just took it down to the water and still not working right, it started fine, bogged down reaching about 15mph, then started to pick up and go well then cut out and wouldnt start again, not even on the trailer, not sure what else to check,
