Yamaha Impeller & Sleeve Replacement

[@Podboy48101]

Overall great video your description of what you were doing was great and the video was clear and easy to follow. However, I've been a mechanic for over 30 years and the way to torqued the retaining nut is not a good idea. You had about an 18 inch wrench and you weigh around 165-185lbs and then you were bouncing on it. My best guess is, you torqued the nut to around 300-350lbs. A better way would to still put the wrench on the retaining nut and to use a Torque wrench on the end (where you had the breaker bar) to get the correct torque setting of 125lbs. 125lbs isn't that much in comparison the average 1/2 inch wheel stud on a car takes 100lbs and that can be done with a 2ft torque wrench with little effort. And it's never a good idea to bounce while torqueing any type of bolt or nut. If you are worried about it coming loose just us a little bit of red loctite.

[@kckrol85]

Is 125lbs the official Yamaha torque spec?

[@jasonmekush5280]

16.5 yeah u def know how to get good top end out of the gpr, just about the same as mine - 21 gpr 85mph. cavitates but still managable ty 4 the nice informative vid

[@JeTsKi_MiSfItS]

Seal your intake grate and use a lucky 13 cone. That helps a lot with cavitation

[@muddytruck858]

Hi Rob, Thanks for the great video. had no clue you could remove the wear ring with out dry ice or a high interest credit card.

[@JeTsKi_MiSfItS]

🤣

[@mikeyesp1100]

Great video. I'd like to know how you check the impeller shaft for being warped

[@JeTsKi_MiSfItS]

Measure with a feeler gauge around between the impeller & wear ring. Should be even all around

[@bobjohnson9687]

Thanks for all the great info!

[@IDVDalot]

Wow it really looks like you know what you are doing! Do you have other fix it vids? Like maybe replacing a starter motor etc

[@mrbmp09]

You are checking clearance, NOT tolerance. In terms of measurement, the difference between the maximum and minimum dimensions of permissible errors is called the "tolerance." Clearance is the distance by which one object clears another or the clear space between them.

[@jasonmekush5280]

i use the nose cone im happy w 85, my mechanic told me it helpd reduce corrosion i trust mi mechanico

[@sgt7000]

You guys are awesome!!!

[@JeTsKi_MiSfItS]

Thank u!

[@crazyrebuildz5333]

What would you suggest do for a stuck sleeve that is corroded?

[@JeTsKi_MiSfItS]

Sleeve removal tool or marine mechanic last bet

[@lukepaul2882]

Does the newer 1 piece housing with the removable sleeve fit the older 2019 with the 2 piece

[@stedsonlindley6523]

Yes

[@robertovelez6454]

Great informative video

[@JeTsKi_MiSfItS]

Thank u!

Thanks for the content brother!!

[@JeTsKi_MiSfItS]

Thx for watching bro! Looking forward to our next ride 👍

[@charlestaylor3434]

Curious to see what gaines you see, if any from the 16.5 pitch. What pitch were you running before? I pitched mine down to 17 on my FX but stopped there thinking there's probably a point of diminishing returns and increased cavitation.

[@JeTsKi_MiSfItS]

I only went to 16.5 because this way i can tune the pump with my lucky 13 cone. Definitely will need to add and subtract washers on the cone throughout the year's temperatures

What rpm you doing?

Hi! I don't know if you answer questions or not? But... is it possible to take out and replace a wear ring on a 2019 Yamaha gp1800r SVHO? (Turbo) I've been told no. Or is this what your video is for? (Yamaha go1800r svho) I've heard that you have to by the whole housing. Thanks Jon

[@JeTsKi_MiSfItS]

1st. It's not turbo. When u talk like that to mechanics they know right away they can take advantage of you. These skis are supercharged. And anyone that said that to u is lying. Look up the wear ring for that year and you'll find it. This is your best place to order it from www.4-tecperformance.com/

[@johndeere9650sts]

@@JeTsKi_MiSfItS Hi! You don't know how impressed and glad I am that you responded to me! I looked up the website you told me about. Is this the right part? RIVA Yamaha 160mm Stainless Steel Wear Ring For SVHO (Replaces OEM # 6ET-51312-00-00) If so, is there any way to buy just "the sleeve"... like other JetSkiis? It's so much cheaper. It doesn't look that way, but I thought I'd ask. And thank you for informing me about the JetSki being "supercharged" Jon

[@JeTsKi_MiSfItS]

@@johndeere9650sts no, thats the expensive way of doing it. U can just change the sleeve like I did in this video for much less money. Last time I changed the sleeve it cost me around $150. All u want is just the sleeve which of course would take more labor to change like shown in my video here. If your sleeve is worn past specs & damaged I'm sure your impeller is also. U don't want to take your ski to a dealer for this job. They will likely take advantage of you. A reputable jetski shop can do this for you. What state are u in?

[@johndeere9650sts]

@@JeTsKi_MiSfItS Hi again... I feel bad for asking, you have gone up and beyond what I ever expected you would do. I have searched that website and eBay. I can't find just the sleeve. And your video is awesome! Very detailed. I will be able to do this my self. (Changing/replacing it) Thanks to you! Would you be able to tell me which part and where to find it? I searched "wear ring" and sleeve. I don't know the mm width either. If you have time to help me, that would be great. Anytime. Not a rush. If not, I totally understand. No problem. Jon

[@JeTsKi_MiSfItS]

Gimmie some time to research this further. Upon an initial search I see it's an impeller housing sleeve all in one. Not like in my 2021 FX which just is a sleeve swap. Gimmie some time to confirm. I will get back to u. Promise 👍

[@kingofnewyork3]

Where are you located ?

[@JeTsKi_MiSfItS]

@@kingofnewyork3 we're not a shop. This is just a hobby

[@mitchroberts2620]

If you put the whole thing in a 5gal. bucket of ice cold water for 5 mins, you can just pull it up with your fingers

[@Mooseknuckle713]

He says even then he proceeds to tap on one side of the sleeve instead of using the old one and a piece of rubber to tap new one in

[@JeTsKi_MiSfItS]

Why would u use the old one to tap it in when it's easier using this piece of wood??? I mean if u got this all down I don't even know why you're looking at these videos 🤷

[@bryant4488]

That wrench looks to be more than a foot long and I don't want to assume your weight but, you're probably more than 125 pounds. So, by jumping on this wrench it looks like you're over-torquing the impeller.

[@JeTsKi_MiSfItS]

Over 20yrs doing this. Thank u

[@bryant4488]

@@JeTsKi_MiSfItS I am sure you did it correctly buddy, just letting you know you're saying 125 lbs*ft and then applying more than that.

[@kckrol85]

@@bryant4488 Do you guys know the official torque spec?

[@bryant4488]

​@@kckrol85 You can look up "Yamaha WaveRunner FX SHO Service Manual" and find the torque spec. It says 110 N*m or ~81 lbs*ft.

[@Exhalation19]

Looked like 300ft lbs 😂
