SL 780 Update!
Alright, here we go... finally got some more time to work on the ski, as some of you read in the past, It would not start or turn over, so I bought and installed a new bendix and starter, replaced old battery... Had a guy here who works on PWC's look it over and he replaced a few fuse and some bare wiring in the electrical box, now she finally starts!! took iot out today for a test, and she ran bad... at full throttle she would not budge past I would say 3-4000 RPMS, felt like it was only running on one cylinder, checked all cyl's and compression was good, but I did notice a red light on MFD came on which meant either, its a gas, oil, or heat issue. Had new gas and oil in it, didnt feel like a issue with heat when i popped it open didnt fell very hot, but did notice a extreme amount of smoke came out when I started it up.... lol. (It took on some water from the previous owner, we checked the engine over and its sound) My next step from here would be too check the water seperator and remove the grey wire correct? anything else that might be causing this? my MFD doesnt display any of my engines current statistics... I think I need to reset that as well... let me know brothers

More than likely the float is bad. Try removing the grey wire and see what happens.

When the fuel level is low, the CDI can limit engine power and RPM. The grey wire carries the RPM limit signal to the CDI from the MFD. Disconnect the grey wire, and the CDI will always deliver full RPM.
When you have diagnosed the problem, reconnect the grey wire, and correct the actual problem cause.

would it be bad to permanently leave it off? will it cause problems in the long run? It didnt display a fuel error on my MFD, the red light just came on.
