check your TPS, check you air temp sensor, jet pump impeller, trigger wires...

I would suggest check the engine first if it turnover or not and if the compression is still high on >120 PSI on all cylinders, it's worth the money to repair, it just a matter of looking for parts and waiting for shipment parts to arrive at home.

For the jet boat, assuming we have the same 240 EFI Mercury engine, you turn on the water first make it flow and turn on the engine and you turn off the engine and then turn off the water. For jetski, its the opposite I know I have my Waverunner too... I sold my boat which I usually the primary...

I think you have to check your TPS voltage... You can check it with manual instructions on proper TPS testing, you can purchase the wire connector to be more easier to check the TPS voltage.... it has the specs on the manual..... If it still has no problem then maybe your fuel injector... Check...

If you are talking about the electronic fuel pump in the VST, yes this is the actual pump, same one that I use my self to repair it DIY through manual specs and guidance... This is the same pump that I use that makes my Challenger run after 5 years of not running at all from the original...

You have a gen. 1 engine then, there should be a stator under the flywheel... buy a manual on this forum or paperback manual easier for you to check and go or print the manual here on this forum very helpful just make sure it is gen 1 engine manual.

Did you check also your port side temp sensor.... maybe also you need to change the water separator filter.... Mine is the same problem with yours before... The problem that I noticed is the air temp sensor and change to brand new one and it didn't have a hot/cold start issue anymore, but I did...

Probably your impeller, wear ring problem there.... check it out... seals and space between wear ring and impeller, something caught underneath stays in the impeller, it will impede the water flow and decrease your speed... check your impeller and take a look at it.

check your air temp sensor too... and port side temp sensor... and check also the specs of TPS.... mine was like that before, it stall after running for 30 mins and it won't start and rest for about 30-45 mins it'll start again and realize my air temp sensor is not functioning when I do my Ohm...

I got the gen. 1 engine but I think to check the pressure for vapor tank is the same, it has a pressure valve on near the VST, it should be 36 PSI as far as I remember. Check in the manual on how to check it properly... It measures the electronic fuel pump inside the VST.. per manual specs it is...

It might not be a good fit.. I maybe different size that you bought in amazon.

Hi, post your engine type, so we can help you out with some most common sea doo problems. Thank you. Do you have a Mercury V6 M2 engine or a twin rotax engine?

Yes, no. 1 to check VST electronic fuel pump pressure, usually it is a big problem for a boat that was not started for a while, check also other fuel pump. As soon as you turn on the key prior to starting make sure you hear that clicking sound from the fuel pump. Check the cylinder PSI all six...

Jetboat is always different in maneuvering docks, it is sensitive to your power and also neutral is not a true neutral since the impeller still turning, actual neutral is when you turn of the actual engine while maneuvering. Use reverse to stop the boat in going forward not neutral, it is all...

I believe I have same engine with you with my Mercury V6, I have challenger 2000, Just look at the cylinder psi 120 above is good, check engine turn over, check idle rpm 1200 when load over the water, check rpm WOT 6000 and speed >45 mph at WOT is good. check engine sputtering.
