How To: Supercharger Clutch Slipping Moment Check (Sea-Doo Jet Ski)

Around 100 hours on newer, performance Sea-Doos, and on a periodic basis on older models, the supercharger clutch slipping moment needs to be checked. If it's not within range, the supercharger needs to be rebuilt, or engine performance could be dramatically affected. This how-to video goes through the steps involved in checking the slipping moment of the supercharger clutch on a 2012 Sea-Doo GTR 215.

Great Channel, first time posting... I have seen that there is a custom length L-Ring that goes onto the s/c shaft to increase slip pressure Without having to re-arrange slip washers. Are you familiar with this and do you know where we can purchase?? Thank you for everything.

[@neptuneatlantic4883]

... L-Ring is located between the slip washers and the nut at the end of the shaft.

[@3ftDeepChannel]

No. We go by the service manual which is very explicit about the supercharger slip washers. We suggest sticking with them and not deviating. Good luck.

[@derargentinier8879]

great video , it helps a lot

[@3ftDeepChannel]

Glad to help out. Ride safe.

[@rajaramjet6969]

You guys have some amazing videos, thanks for sharing. Is there any chance that you could share the model number of the torque wrench that you are using please? I prefer a dial, such as in your pictures as opposed to a digital display. I see the brand is CDI Canada.

[@3ftDeepChannel]

Hello Raja, Thanks for the kind words. I don’t have the torque wrench handy right now, but you can find it at our Amazon store here: 3ftdeepsports.com/store-tools-wrenches/

[@giuseppevultaggio4439]

Good morning from the fan nut is it possible to see if it slips by turning with the torque wrench?

[@3ftDeepChannel]

Yes, that is what we use. A dial type torque wrench is much easier and accurate to use than a standard click or digital torque wrench.

[@wayneanthony4343]

2012 GTR215 I sucked up a lot of mud and debris. Now it seems like all the engine power is not getting through the drive shaft to the jet. Engine revs fine but only about half thrust.

[@3ftDeepChannel]

You'll need to clean out your intake grate and pump. I suggest getting it out of the water and cleaning it out thoroughly. Hopefully nothing is stuck in the pump. Good luck!

Hello 3ftDeep and other KZbinrs. I'm going to look at a Seadoo rxp 215 for sale. What are some key things to inspect and make sure are functional. its at 120 hrs, for sure send the supercharger to be rebuilt. Do a compression test, ideally what should compression be at? (does it change from hot to cold)

[@3ftDeepChannel]

Inspect the intake grate for damage, and look through it to check the impeller and wear ring for damage (use a flashlight). There shouldn't be more than a millimetre or so between the edge of the wear ring and the impeller. Check the pump for damage, and also look for rust. Make sure the engine compartment is well-maintained, and that the engine runs. Check the steering for free play. Seat repair can be expensive, so make sure there no tears that can't be easily repaired. Check the oil dipstick for any "milky" coloration or other residues. Also check the oil fill cap for same. Check motor mounts (if you can see them) for cracking or flaking. Check the computer gauge for all functions. For compression, S/C models should be around 120 to 130 psi, non S/C will be a little higher. The most important thing is that they're all about the same reading (+/- about 10%). Also, check out the PWC Show's KZbin video on buying a used PWC ...kzbin.info/www/bejne/j3W4n4iMi558mLM. Good luck!

[@ib1p]

+3ftDeep Awesome. Thank you so much. I've searched countless of hours online to find a check on what to check when buying a supercharged pwc. I'm just waiting for the weather to warm up a it to ask him to take me out and test it on the lake.

If the supercharger doesn’t have enough resistance to turn the engine over without spark plugs, does it need to be rebuilt? I’m trying to get the lines at the top but it keeps slipping…

[@3ftDeepChannel]

How many hours does your supercharger have on it and how long since the last rebuild? Have you checked the slip?

[@Ajdjdncjekskf]

Is there a way to check without tools? Saw a ‘finger method’ on a forum. Would you reckon that would work?

[@3ftDeepChannel]

We haven't seen that method, but the slipping moment range is very specific. Can't imagine how you'd do it accurately without a torque wrench.

[@Ajdjdncjekskf]

3ftDeep Yeahh it basicly says; can move easily, bad, probably engine damage.. Can move with lot of force, needs replacement.

[@3ftDeepChannel]

@@Ajdjdncjekskf I wouldn't go by that advice.

[@etc7411]

What if it’s out of spec? Can you change the pressure with the supercharger on the ski?

[@3ftDeepChannel]

No. As long as you’re using the right oil, if it’s out of spec it would likely need rebuilding.

[@mrfiera]

I installed a bigger SC wheel a 17.5 lbs one to be exact, at how many pounds should I set the torque tool to make sure it’s where’s supposed to be ? Thanks

I'm not sure. I suggest you contact the manufacturer for the exact specs. Good luck.

So sea doo says rebuild super charger 3 year or 100 hours I ride 5-6 hours a year change the oil every year with sea doo kit its been 3 years if the torque is in spec what are your thoughts Thanks Doug

[@3ftDeepChannel]

That sounds like a very short time for a rebuild. Are you getting that interval from the Service Manual, or from the Sea-Doo Dealer? For most newer machines it would be 5 years and 175 hours. What year and model do you have?

[@antonirandell8556]

Hello 3ft deep.... How much resistance should there be if I try to turn the supercharger impellar by hand please. And when you do the check in this video am I looking for the supercharger to slip or checking thst the bolt is still tight Thanks in advance

[@antonirandell8556]

Connected to the engine that is

[@3ftDeepChannel]

When it’s still connected to the engine, there should be considerable resistance. What we are checking in the video is how much torque it takes before the impeller spins free from the engine. It is engaged to the engine like a clutch. Does that help?

[@tylermcbride2807]

How much does it cost to fix the slipping. My rxt x 300 2019 sometimes runs at 8100rpm with the Riva scom then drops to 6700rmp could that be the supercharged or something else.

It sounds like your speed limiter is still kicking in. Are you sure your SCOM is connected properly and working?

3ftDeep Thank You

[@xmfchang3711]

So is the torque wrench you are using diffrent from a torque wrench you would use gor example head bolts? Can i just use a regular torque wrench and tighten it down to 8nm? Please HELP! Thanks in advance.

[@3ftDeepChannel]

We have a number of different types of torque wrenches, each with different torque ranges (i.e. some delicate ones, some more robust). So the answer is "yes" if your torque wrench accurately reads within the range you're using it. In other words, you don't want to torque to 8nm if the range of your torque wrench is 5Nm o 200 Nm. You should use one that has a range of 1 Nm to 20 Nm, for example. You also need to ensure you're following a service manual very carefully, as many stretch bolts require a torque, followed by an additional turn to a certain degree. Good luck!

Is the supercharger wheel supposed to spin on its own by hand with little friction? Or not suppose to spin at all?

I have a 17 RXTx 300, problem is the supercharger will spin with some resistance while on the unit with engine off. The dealer replaced the supercharger and this one is found the same thing.. kinda stumped. Don’t think it should spin by hand ...

[@3ftDeepChannel]

Eat does spin "by hand" even when it's in the engine, as it has slip washers. It shouldn't be easy, though. Sounds like it's still on warranty, so I'd let the dealer "deal" with it. Why did you take the supercharger off in the first place on a new machine? What was the problem?

how much would it cost to rebuild my 2004 GTX 4-tec limited supercharge engine? i hydrolocked it on cylinder #1 with only 20 hours into it and its been sitting for 10 yrs in front of the house. Do you do that for people? where are you located? i would like to increase the HP on it as well. your advice is greatly appreciated. Thank you ahead of time.

[@3ftDeepChannel]

If it’s been sitting that long with water in the engine, it would be cost prohibitive to rebuild the engine and make any economic sense. It would be better to buy a new machine, in my opinion. We are up in White Rock, Canada. Good luck!

[@3ftDeepChannel]

I would budget about US$2,000 for the engine, US$350 for the supercharger and depending on what the drivetrain needs if it’s a pump rebuild at least $500 US.

@@3ftDeepChannel ok do you just recommend getting a rebuilt engine? I was hoping to increase the HP . the haul is in prestine condition. if so do you know of any online place I could buy one from? are those reliable? do you know of a place where the reuilt engines are performance tuned better than OEM?

[@3ftDeepChannel]

If you're committed to your 2004, then that's what I'd do. The problem is that it is an older machine, and parts are expensive. I see boats very differently than cars. If my car breaks down I can pull over to the side of the road, get ticked off and call someone to come get me and tow it home. If my boat has an issue 25 miles from shore, that's a different story... For that reason I would never keep a boat (that I hadn't been constantly maintaining) that was over 15 years old. Actually, my rule is closer to 10 years old. If you ride in safe places, and have confidence in the integrity of the rest of the machine (electrical components, for example) and are committed to keeping it running well, then you could consider rebuilding the engine (we wouldn't buy one, as it's much more fun and satisfying to rebuild them). First, I'd pull the engine and take it apart and see what shape it's in. If it's in decent shape, I'd rebuild it. If not (and you are sure you're going to keep it), then I'd buy another engine. I wouldn't bother trying to increase the HP though. We found that the best way to increase HP in used machines is to just replace the wear ring in the pump. Just a little wear on those can cause you to lose a lot of HP. Also, a damaged impeller (that can be fixed by Impros) can also cause you to lose a lot of HP. Check those things out, first. That's what we'd do. Good luck!

Great video, thanks, just a side note, would this be exactly the same way to do the slip check on a 2020 RXTX 300, or are there a completely different set of procedures and, if so, where would I find the procedures online? TIA

[@3ftDeepChannel]

The best way to check for differences is to get a hold of a Service Manual for your machine. I don't believe there are any procedures posted online (that's why we started our channel), and I can't honestly say if what the differences are. I can say that some people short-circuit the process by jamming a piece of wood in the impeller (so it won't turn), and turning the supercharger nut to check the slip that way. It's probably not as accurate, but it worked for them. Good luck!
