1991 Sea-Doo sp engine stutter.

Okay so the problem has gotten worse and I’m having a lot of trouble with the ski. It’s slowly dying but each cylinder has 150 psi, it sputters and sputters and dies. Idk what’s going on but I don’t think it’s electrical. This is what the plugs look like any help would be amazing thanks!

There's got to be a fuel problem....

Possibly but it’s odd that it’s progressively getting worse.

Have you searched the 2 stroke forum only to see if someone has a thread started already that would relate to your issue?

I've done alot of work on my 91/92 xps and this site helped this carpenter/ armchair Seadoo mechanic, immensely!

You need to rebuild the carbs with OEM Mikuni parts. The plugs look like they are running lean.
