    RESTO 1996 Speedster MPEM Fuse Holder Identification

    Can anyone identify the 4 fuse holders on the mpem? The service and operators manuals and all online images are for a different year I think, seadoosource is the only site with a picture of this computer but the fuses aren't labeled there either. It's 2 horizontal one above the other, then 2...

    SBT Cylinder Prep

    Is this pretty normal for SBT Cylinder Exchange?? I've had nothing but problems with them so far, so par for the course, but I went this way so I could avoid needing machine work on my cylinders... I just noticed this one, so I'm gonna have to go through all 3 I guess. I'm not really worried...

    Trying to pick a ski

    I doubt there's any new opinions, but I've got a Js550 and 650SX both in front of me right now. I really just want something I can get the most out of in flat water. I rarely have more than chop to jump, so I was leaning towards the 550 thinking it's lighter and simpler, probably takes less to...

    Rough Spot In Throttle

    I've been playing with my carbs since I cleaned them, got great advice, it's going pretty well, but I've got one spot in my throttle that my ski just runs really rough. It's like it's missing on every other stroke or one cylinder isn't firing maybe. I can't say that's not it's typical feel, it...

    Plug Reading 787 GSX

    My read on this is good on the PTO side, MAG side is rich fouled? Or is that oil fouled? I'm getting light white smoke out the exhaust at idle Oh, forgot, I also closed my gap to .020ish from closer to .023+, so maybe I'm not getting a clean full burn as well...? I can't back my oil pump much...

    Cavitation After Fuel System Work....?

    I've been chasing a slight miss all season and the last time I took it out I pulled the seat to find the entire engine shaking, (Misfire on one cylinder) so I just pulled out since it was the end of day anyways. Figured enough was enough, pulled the carbs off and stripped them. Sure enough, both...

    Can someone help me pick carb rebuild kits?

    I'm trying to avoid the cheap junk ones, but when I go to reputable sites like Bay Area, I get different results by year, but then a lot of the kits say they'll work on any of the carbs except some specifically say 787 only etc, and then almost all of them are aftermarket, so I'm concerned about...

    Power To Weight Ratios, Engine Pros/I've go

    I've got a few extra engines around, even thinking of stripping my odd GSX, and was looking at different ideas. So I got this ideas simply from riding my girl's first ski before I decided to sell it. It's a white 580 SP hull, probably 95. It's honestly just stupid fun. I love it's nimbleness...

    1¼ Out From What?

    Low speed set screw- 1¼ turns out from "slight resistance"? It's screwed into a spring... Is there something a little more concrete as a starting point? Or should I just run it a bit rich and slowly adjust?

    657 Confusion Again (Top End Exchange, Vendors Don't List Correct Parts/Engines)

    None of the vendors list a GTX from 1994 with a 657 engine. It's like they went from the 587 to the 657x. I've already asked about this once, and was told "Sea-Doo never sent out machines that didn't match their engine and year, etc", but yet again I've got 4 GTX made with 2 different engines...

    Refill All Oil Lines

    I'm replacing oil lines on multiple 657. It's easy to find pictures of the bleed screw for every other engine, and the manual just says (typical) and a picture, but I think I found the bleed screw. But the main ½" line to the left side of the block from the tank will not fill with oil. There's...

    657 Confusion

    I always find it challenging to nail down exactly what each new ski I bring home is exactly because what's in them seems to always be a bit more fluid than what the PWC wikis and even SeaDoo service manuals say. Right now I'm working on a 95 title/94 hull SP, no real confusion, also have a...

    VTS Restoration Thread?

    I've gone through 6 skis now with a VTS, none of which worked (I've never seen one that works when I buy them), and after being irritated about my personal ski for a couple seasons, started tearing into them. No where online have I found an actual restoration or rebuild thread. Sure, I've seen...

    VTS Rebuild Question

    I can't find anyone whose rebuilt their VTS motor. Found an article a couple weeks back and can't find it now. Anyone rebuild their motor? What kind of assembly grease/oil did you use?

    Impeller Questions For Older SeaDoo

    I've got a Solas Supra SD-SC-D impeller that's in reasonable shape that I was thinking of replacing my stock 97 GSX impeller with. The stock one is ate up and the blades were actually bent up a good ½" or so on the back side tip of one. I straightened everything back out, but I'm trying to...

    Which Wear Ring Is Right

    I'm looking at wear rings and there are 2 part numbers for GSX models coming up. I've got 290 and 653. Is there an easier way then going out and using calipers to find size? I have another pump that's a 290 but the area behind the ring looks to be same, so idk if the ring is just thicker one. Or...

    Impeller Reconditioning Services

    Does anyone know if a impeller repair option for Michigan? Every place I've tried off Google has been a flat no. I've got a pile of impellers and have been debating replacing them, but a couple are nice performance upgraded ones, and not in bad condition in my opinion, tho I have to admit I'm a...

    RESTO Wear Ring Removal Oops

    I have a trashed housing missing chunks of the fins, so I figured I'd do a fuck it run on it to remove the ring. Looks like most are rubber over white plastic. I went a little deep and there's a def score. Doesn't matter here, but when I get into my good one, how big of an issue is that? I know...

    RESTO Impeller/Ring/Assembly Troubleshooting

    Hey ski fans! My skis seem to house fricken gremlins, so I'm trying to break up problems by area. I'm on season 3 with a 97½ GSX and a 95? SP. I've had this weird issue since the start where occasionally either ski will rev out with barely any acceleration whatsoever. At the end of the first...

    RESTO 97 GSX 787 No Beep Code

    I went through this last year, my ski wouldn't start, and I couldn't figure out what the hell was the problem as apparently it doesn't beep anymore. I have a 96 I bought today, and see what it's supposed to do (97 may have when I bought it, but quit second season). Besides the fried VTS, (I've...
