runs but then shuts off

[xarnes10]

ok when my seadoo is just idleing it runs fine for 15 seconds and then shuts off and i turn it back on it runs then shuts off like the rpms start to drop and turns off but if im giving it gas it wont turn off but when it idles it will shut off? what could this be

and the gas is from last season idk if that will effect much same with oil

and i have also had a multi meter hooked up to watch the battery when i give gas it goes 13 to 14 but when idle its at 12ish but i do see sometimes when the engien is about to turn off the volts go down to like 10 and less and it shuts off idk if this could be problem battery was tested works fine and i took it off the charger been chargin 2 days and ski still shuts off when idleing

oh and it does seam i have a small exhaust leak on the inside could that be it? and tips on how to take exhaust out

I'm not trying to be harsh... but it's WAY to hard to read. Please try to simplify what you are trying to ask.

ok sorry about that short version is when its idleing it will shut off when im givin gas it will stay on

 

[Dr Honda]

OK...... that's easier to understand.

Is the idle too low? It should be 1500 rpm in the water. If that's the case... raise the idle a little.

Since you have an RFI ski... there could be issues with low fuel pressure... or bad injectors.

ok mine idles at 1000-1200 in water how can i adjust this
and what about out the water what should rpms be

 

[Dr Honda]

Out of the water it should be closer to 3000 RPM, but that's not a real concern. The adjustment needs to be done in the water.


Directly on the throttle body, there is an idle adjustment screw. Just give it a tweak to correct the idle.

Last thing... put in a fresh set of sparkplugs too.

but when i run it out of the water it shuts off too do u think its still thinks its the low rpms

 

[Rotor13B]

You say you have an exhaust leak. Does it stall out with the seat off? Carbon monoxide could be choking you engine, Throttling the engine pulls in enough air to overcome the Co2. Even if that's not the root of the problem it's not helping. Sounds like it's not getting a complete burn and the plugs are loading up and it stalls out.

 

[xarnes10]

Yes it does stall with seats off well ill get new plugs these seam fine and ill try to adjust the idle rpms

 

[xarnes10]

ok i changed spark plugs previous owner had wrong ones it and i turned up the idle speed and works wonderfully now thanks for all your helps
