Why Check Your Impeller & Wear Ring: WCJ Quick Topic

[@manusengelbrecht9959]

Thanks for taking the time to make these videos. I have a 20 year old Yamaha GP1200R and trying to make sure all is good, and these videos help

[@watercraftjournal]

Glad you like them!

That’s what happen to me a few weeks ago , was washing the out on the trailer and the ski was bouncing up and down a little , propeller, wear ring and bearings all needed to be replaced ,

[@watercraftjournal]

Ouch!

[@CP-kb1du]

Thank you for the information ..... have old school 90's xp's staying plastic ...

[@watercraftjournal]

You bet!

Thanks for the reminder :)

Any time!

Great advice

I have a 1996 kawasaki time capsule. Less than 30 hours. Been going amazing Today while riding I felt that slippage, lack of power. Assumed wear ring but seems like kawi’s aren’t as common to need them. Putted back and loaded it then noticed some weeds and a piece of bag wedges in my ride plate. Before I go ordering parts. Could it just need to be cleared out and inspected? Not sure how common these issues are on the kawasakis.

[@watercraftjournal]

Kawis don't have plastic wear rings. It could be a bunch of different things.

[@JoeMaxFpv]

@@watercraftjournal I dropped it off at the kawi dealer. Hoping it’s just remnants of the plastic bag wrapped around impeller. I looked in from ride plate and Impeller looked brand new. So hope it’s just junk where it doesn’t belong.

Your channel is amazing and very informative! I just bought two GTR215s without water testing and finally put them in today. One was amazing - the other didn’t get above 32 or 5400 rpm’s. Engine sounds strong but all felt rattley. Do you think it’s the wear ring?! Does that cause lack of pure acceleration and terrible turning response?

[@watercraftjournal]

How many hours on the other one?

[@thomasberezansky95]

@@watercraftjournal they both have 100 going in to yesterday. I’ll add that outside the water I could rev up past 7000 rpm but just absolutely bogs in water and loses all momentum in turns

[@tylerclark582]

Yes, however your impeller can also be chipped from foreign debris. Your intake grate helps, but rocks and ropes tend to do damage. Especially if it’s repeatedly abused. - Owner of TC Watercraft And Desert Mobile Repair. Yucaipa CA.

[@thomasberezansky95]

@@tylerclark582 How can I know what the proper diagnosis is then for a fix? I've looked in both intake and lifted the IBR to inspect and no signs of anything stuck. The impeller is also in fine working order IMO

[@tylerclark582]

@@thomasberezansky95 the only true way to tell is inspection both visual and with a digital caliber. First removing any trim, steering or reverse cable off the nozzle of the jet pump. Second removing the water lines both too and from the motor, yamahas also have a streamer to disconnect. From there you need to take off the 4 (long) bolts holding the nozzle to the jet pump off. You’ll see from there the jet pump slides off. You might have to take out a bolt or two and another house or whatever I may have left out. But that’s the process for most skis. Once it’s apart it’s usually another 3 bolts inside to pull the wear ring. But first looking at the side closest to the intake you want to see if that inner lip of the ring is significantly scuffed. Sometimes that’s the only part of the ring that is, and it causes extreme issues. Usually gap clearance between a wear ring and an impeller is somewhere around a half millimeter. Anything more and it leads to pump cavitation. PRO TIP: Removing the ride plate by jacking the ski up might make this entire process easier. However please secure the ski so nobody gets hurt.

They are lefthand threaded. So the harder you hit that throttle the tighter they will tighten up...

[@mrvoltman1921]

What does a healthy Yamaha wear ring look like? Mine, new to Yamaha, looks scored like a piston cylinder was just honed. Prop edges are perfect and tight agains the wear ring.

[@watercraftjournal]

"Freshly machined" is ideal

[@IDVDalot]

very nice thanks

[@NatureBoyMel]

What if your sea-doo makes a noise when shifting from drive to Neutral to reverse?

[@watercraftjournal]

What’s the noise like?

[@NatureBoyMel]

@@watercraftjournal almost like a hard shift with a wiring up sound. Do you have an email ?

[@watercraftjournal]

Yes. And a website.

[@siyuanliu5451]

Should wear ring of Seadoo be replaced at certain interval?

[@watercraftjournal]

No, only upon visible damage/wear.

[@salscavetti834]

Was expecting my ring and prop yesterday new machine 21 seadoo gtx. Prop looks fine so does ring but I did notice on the ring it almost looked like a black or silver dot almost as if someone took a sharpie marker a made a dot. Any explanation?

[@watercraftjournal]

Unlikely anything important- nothing more than an inspection cover.

[@investingthelike111]

if you have just repaired the propeller bearings and the everything is fine , if the wear ring is not fully smooth Is it fine to ride until a new one arrives? I take it ,that it would just lower performance not damage anything else?

[@watercraftjournal]

Sorta. The oblong oscillation will exacerbate the damage and further injure the drivetrain. Best repair it all.

[@investingthelike111]

[@joeb9135]

does doing impeller and wear ring yourself void your warranty?

[@Flippingcars4cash]

Can you hammer it straight?

[@lovinhouse374]

How many hours can someone expect out of wear ring on a Yamaha or Seadoo given normal use (no shallow water)?

[@watercraftjournal]

Yamahas have stainless steel rings, which don't require changing unless there's signs of severe damage. We've heard of plastic Sea-Doo rings lasting upwards to 150hrs. It all depends on the degree of wear.

[@lovinhouse374]

@@watercraftjournal Thank you for the reply!

[@frankbarbara1899]

Any special considerations for a Kawasaki 15F or is this similar to a Yamaha?

[@nikosgrigorakos]

@@watercraftjournal If the plastic Sea-Doo rings last up to 150 hours that basically covers the average life expectancy of a Sea-Doo engine .Now i know why Yamahas have long lasting stainless steel rings!!!

[@watercraftjournal]

Again, 150-hours isn’t the standard (some fail within 20 hours) - it all depends on whether the ski is operated safely and correctly.

[@arturocordoba6206]

Took my 2021 sea doo gti 130 today I had it in eco mode had a small rattling noise at the rear end but when I change it to sport mode the rattling noise and vibration became more intense. Could this be the impeller and the ring?

[@watercraftjournal]

The impeller wouldn't make that kind of rattle against the plastic wear ring. That sounds like a pump bearing but your ski is really too new for that kind of failure. Are you sure you're just not misidentifying the exhaust noise?

[@arturocordoba6206]

@@watercraftjournal I've never heard that noise before and yesterday I felt something went through the impeller and today while making that noise and the vibration it also loss speed the max speed was only 43 mph

[@watercraftjournal]

Did you bother to check IN your pump at all?

[@bubbavasquez1744]

When changing out my Prop since mine looks like a steak knife lol, do I just order the prop or do I need to replace the seals too or no? Ty

[@watercraftjournal]

You can of course, but it really depends on their condition.

[@bubbavasquez1744]

Changed the prop today , took me about 2 hours. Local fabrication shop helped remove the prop for cheap. Now I’m ready to see n feel no more vibration

Great video brother and good advice but is that a fuckin tv in the background? What year are we livin in
