runs great till half tank

[dieselstroke]

I just got back into seadoo's. years ago had one did same thing and was told carbs were gravity fed till half tank and was told a trick to get the fuel pumped after that. Any clue what to do? had both mine out today and both started bogging at half

The carbs are not gravity fed on these at all. They use a pulse operated fuel pump on the mag side carb to pull fuel out of the tank. If you’re having problems at half a tank like that, the first thing I would check is the vent line. You can also loosen the gas cap and if that helps, you’ve got a vent line check valve that’s gone bad...

What ski do you have?

The older ones were known to have the fuel pickup hoses rot off so that could explain why it runs out of fuel at 1/2 tank.
