Hi there! First time post here.

Hi there. I am trying to take out my supercharger from my 2009 seadoo speedster 150, 215hp jet boat for service. I have watched the video (on a jet ski), but I can’t get the 3 bolts off , they don’t appear to be 6mm or 8mm. They aren’t torx, they are regular hex bolts. I have un done the strap for the water box and the j pipes for coolant but I’m not able to push the water box back to give myself any more room. The bigger issue is I can’t seem to figure out the size of bolts. And basically have no access to them, the layout is different in the jet boat and really tough. I could feel the bottom bolts but not see them but the top bolt have virtually no room to get wrench in. Help?

Wish I could help. I have the same boat but with the non-supercharged engine. Lots of room to work on mine.

I've had various issues over the years, some of which I was able to resolve. But I also found a good, trustworthy mechanic who was able to fix the things I couldn't. Any chance you have somebody like this? I bet he/she could answer your question in a heartbeat.

I live in southwest Montana, just moved back here , this time with a boat, and nobody will work on the supercharger. Places will work on jetskis, but not this boat. Which is frustrating because it’s the same engine as a lot of jet skis

Update, I got it. All bolts were 8mm, and had to use SIX POINT 8mm box wrench for the top bolt. not a 12 point standard box wrench, the 6point to get torque on it.

Good job. I rounded off enough bolts with 12 points over the years I try to use 6 points all the time now. Not always easy to find, but worth it.
