I checked all contact points and even cleaned off stator but it still needs replacement to be sure. previously submerged. Since then rebuilt motors starters etc. stators have not been replaced but looked good no rust corrosion , check out ok but appears system isn't charging up to par

I'll do this next. If fuel pump is bad can it be a larger draw and causing low voltage readings?

I've pulled the pumps and cleaned tanks. Filters looked good so didn't replace against better judgment.

Both skis were under water without being properly dealt with as you can see in pic of one of the engines, at some point so I wouldn't be surprised if the statues were bad

Actually I think if filters are crumbling the injectors could be getting clogged after a few minutes them when off the sediment can clear or settle then get stirred up again when running

FI Work good. I cleaned and tested.

It doesn't shut off like key removal but like stalls from lack of fuel. If it's the fuel pump or filters then why would it run great for 5-10 min then start bogging and stall then in 10 min run fine again? But I know anything is possible. The stator checks out but as someone said can still not...

can you tell me what fuel pump from advanced will work in this ski? Thanks

whats a good stator manufacturer for these units

ive put 2 OSD rectifiers in it Im confident its not the rectifier. Thats 4 different rectifiers 2 new high quality and 2 oem. I think its the Stator. If not mpem is in question.

Sounds like stator is not working properly but is within spec on all tests in manual? What do you know about the water temp sensor and air temp sensor with the .94. .92 resistance readings? per manual testing procedure. Can one of these or both of these cause a rich condition? ie they...

am i understanding this right. If charging system isnt up to par then over time (5-10 min) the ski losses its ability to adequately produce the spark to burn the fuel. ???

i have 2 NEW OSD 4 tec rectifiers and have and tried them both. There higher output and highly recommended.

just rechecked battery while rev to approx 3500-4000 rpm and voltage does increase from 12.14 to 12.44.

so as i stated the air temp and water temp sensors only show resistance of .96 and .92 while 90 degrees outside. Should be 2.86-2.374 with 70 degrees ambient temp . any thoughts on this. i have not reinstalled the hull air flow tubing , could that be a problem I wouldn't think so but IDK.

I concur but the rectifier is new OSD and the stator checks out with Manual testing procedures. so I'm stumped Obviously

My thoughts are its rich and the spark gets weak after heating up? Coil, water temp sensor, air temp sensor stator checks out , rectifier is new , battery is new, only charging to about 12.11 with 3500 rpm though. does not increase voltage with RPM up to 5500 OR if what you say is also...

air temp sensor resistance is .96, water temp resistance is .92 but its 95 degrees outside the specs are 2.8-2.73 in 70 degree weather. Does temp matter that much?

stator checks out. Black dry soot plugs definitely means Rich for these? If it was rich wouldnt the plugs be wet with gas and have gas smell(not wet or gas soaked)

Probably key to start.
