Hey guys,
Nice to meet all of you in advance. New Seadoo owner here, joined to ask for advice and see if anyone could help me troubleshoot and learn more about my new toy. I just acquired a free 2005 RXT Supercharged, only because the PO got a quote for excessive engine damage. Instead of junking it, he said i can have it if i can fix it lol!
Now, the shop ticket he shared with me says "unit is very noisy, check supercharger sounds blown. Check for faults, found MPEM com fault error to cluster (sending unit not giving correct info to MPEM) MPEM needs to be replaced. Found coolant level very low. If supercharger let go, engine rebuild required."
Now, since then i used my mini camera probe to look inside the cylinders, supercharger, and intake manifold. Ive found no evidence of mechanical damage. All cylinders look good and clean, some light corrosion on cylinder 2 piston head but nothing huge. All spark plugs were fithly, but electrodes werent worn out at all. Supercharger on my scope looks clean and no signs of mechanical damage. It also feels sturdy when i try moving by hand, as in not super loose or alot of back and forth play. There is some play it, but no more then i feel would be excessive. Also no debris found inside the intake manifold.
PO said its starts up and idles fine, but the moment you pull the gas to go it shuts down. They stole the battery out of it for their other seadoos, so im waiting for my new one to arrive before i can confirm this. But since then i have been going through the engine compartment, nothing out of the ordinary. Its clean, no signs of leaks, smells like an engine room lol.
Now all that said, do you guys have any recommendations for me to pursue? Ive done some reading on the site, planning to chase and clean all electrical grounds, drop some marvel oil in the cylinders, replace the plugs with new, plan to unplug all electrical connectors and lubricate for continuity. Steering cable seems to be a little tight, it might need replacing. My concern right now is thw engine. What do you guys think? Thanks again in advance for any help. All suggestions are appreciated!
