Outboard Jet Maintenance Sharpening the Impeller

[@AlvinDedeauxFlyFishing]

Let me know if you have any questions or if I left anything out.

[@aarondamron3409]

A couple tips to those looking to service your impeller assembly: -The washers that come with the jet pump seem to be thick, remember you can get them in varying thickness to help with shimming it, just keep in mind the overall thickness of the washer group when trying to find your sweet spot. -If you need to replace the washer that holds the nut in place, it is called a tab washer, make sure you get one in a material that will work with your existing materials, you don’t want to cop out and buy a quickest/easiest tab washer only to have it start a chemical reaction within the rest of your assembly costing you way more in the long run. I used to be in industrial sales, these are a few things most non-industry people may not think of. Keep up the great videos!

[@AlvinDedeauxFlyFishing]

Thanks for the tips!

[@ralphdetloff8300]

One thing I learned at outboard school was to check clearance between liner and impeller with feeler gauge. Actually adjust to thousandths of an inch

[@blackearthanglingco.1487]

I like slide on the impeller without the key, then slide on sleeve (with my adjusted washers). You can then spin the impeller to double check it doesn’t rub on the sleeve. Then slide it all off and for final reassemble. Cheers!!

[@AlvinDedeauxFlyFishing]

Awesome tip. I'll try that next time.

[@highadventur]

Yes sir. That's the ticket.

[@isaacbarragermusic]

10/10 video. I’m brand new to jet pumps, and this was a video I was most certainly looking for. Thank you brother

[@AlvinDedeauxFlyFishing]

Thanks for watching!

[@colbymyers6278]

The easiest way for me to check clearance on the wear ring is to spray paint the inside of the wear ring and install it. I only put 3 nuts on the jet foot and turn the engine over with the starter a couple times. I shim it out until it removes some paint and back it out 1 shim.

[@viciouscycle8890]

Slather the cone where you see marks with lapping compound and improve your tolerance. Wipe the crud out, good to go.

[@douglarson432]

Thanks Alvin. Great tutorial.

[@aktrapper6126]

I usually just put the impeller in with the shims I believe I need without the nut, I then put the sleeve in and hold it up by hand pressure only, I then slide the impeller up and down to see how many more shims I need to add or take out. Its fast and easy.

[@AlvinDedeauxFlyFishing]

Thanks for the tip!

[@lucain1111]

You can also use a business card to check shim clearance.

[@AlvinDedeauxFlyFishing]

The folks at Outboard Jets told ne to tape 2 business cards to each blade before assembly to get it aligned.

Thanks for the great information. Good information when your marina is 2 months behind on repairs.

[@AlvinDedeauxFlyFishing]

[@brentmcmahon8188]

The wings on your jet foot do good on the lake and had shop make a set them out of stainless and adds strength to the foot and they keep the foot from sucking every little wave you go over. Make out of stainless they are very hard to bend to and protects your foot and the do help steering too.

[@NelsonCobb]

Good stuff! I just bought a jet drive so I need all the information I can get

[@AlvinDedeauxFlyFishing]

[@rippinlips8680]

Great video thanks. I’m not scared to take min apart and loo at it now. I learned a lot.

[@AlvinDedeauxFlyFishing]

Yeah, it's pretty simple, and you might have to take it apart on the river one of these days.

[@nate4036]

Alvin, you ever considered Outboard Rock Ejectors? They have a new “top notch” kit that is a polymer intake with their stainless grates.

[@AlvinDedeauxFlyFishing]

I have seen them. Most of our issues are with weeds.

[@nate4036]

@@AlvinDedeauxFlyFishing the Tn river is nothing but weeds unless in the channel. I feel that wholeheartedly

[@acvyouthfootball3544]

Solid video with excellent picture and explanation!! Thank you!

[@ralphdetloff8300]

One thing I was taught is to check clearance with feeler gauge

[@TheSilverSurfisher]

⁠ Greetings and thanks for the informative, great video. How do you re-smooth out the scratches on the surface of the wear ring/sleeve ?? And will it interfere with the tight tolerances needed between the impeller and the sleeve?

[@AlvinDedeauxFlyFishing]

The only way that works for sure is to replace it. They are pretty inexpensive. I have heard of people filling in the grooves with jb weld but I haven't tried it.

[@TheSilverSurfisher]

@@AlvinDedeauxFlyFishing Thanks and Appreciate your feedback!

[@mikescustomtackle9898]

You sharpened it backwards. You need to sharpen the upper edge and then blend it in so its a smooth transition. It need to be done that way to pull the water into the pump. Also always grease up the shaft and other surfaces so it comes apart easier the next time.

[@AlvinDedeauxFlyFishing]

Yup, I'm thinking about doing another video on that. Good tip on the grease as well.

[@pauleyplay]

good catch Way to go

[@highadventur]

He did it right.

[@user-ur5hv6yn8k]

He sharpened it correctly, kinda lacked in the measuring of tolerances. And you should clean up your wear ring before installing, you loose a lot of pressure in the rough surface.

[@TheSilverSurfisher]

@@user-ur5hv6yn8k And how do you “clean up” the wear ring/sleeve ??

[@piperguy76]

Good work!

[@AlvinDedeauxFlyFishing]

Thanks!

[@oby-1607]

Looks like somebody likes to go in the shallows. Rocks and sand are hard on all of this.

[@tommiller5612]

My intake is all beat up and the bars Are bent .it is so bad I don’t think I can replace the bars Will replacing the intake shoe help much with performance

[@AlvinDedeauxFlyFishing]

You can remove the grates and replace them. Shouldn't need to replace the foot unless it's cracked.

[@2lovedrive]

Так и не сказал как заточить импеллер, какой угол, куда скос кромки. А у OBJ есть даже картинки, как правильно точить и угол.

[@joekopchak1651]

Very informative video. Thank you. I own a 1996 Johnson 50/35 outboard jet that I run on the Delaware River. Already had the impeller off to sharpen and set clearance . My housing is frozen inside the pick up. Did not want to get crazy trying to get it out. Do you have any tricks for this circumstance

[@AlvinDedeauxFlyFishing]

The foot of the jet is stuck?

[@highadventur]

You mean the sleeve. I'm assuming that you got out out by now. Tapping, wiggling, prying .. and heating the foot if necessary.

[@sammyandbritnee7668]

How about a stuck propeller if it doesn’t pull out what could be the problem then ?

[@AlvinDedeauxFlyFishing]

I haven't had one completely stuck. Usually a few taps with the hammer works. When you put it back in make sure and grease everything up so it comes out next time.

[@tillerjets]

An easy way to gauge your clearance is to use a business card. Great video though!

[@claytonduncanATX]

Alvin- I have a very similar setup- Hog Island + Tohatsu jet. At 2:10 in video- I noticed you have a plate attached to hull that looks like it might protect the impeller grill from big rock strikes. Is that what it’s for? Also noticed you have two “phalanges” on either side of the impeller grill. What are those for? Thanks! Love your videos/ soundtracks

[@AlvinDedeauxFlyFishing]

The plate is a splash guard. It cuts down on the water spraying up from the foot. The fins are called deep water fins I believe. Outboard Jets sells them. They help to keep the pump from sucking air in choppy water or if you trim the engine way up.

[@acurarl9929]

Why didn’t you clean the leading edge up more then you did? Still looked like it could of been cleaned up alot

[@tegdejonge]

My impeller isn't sliding off so easy. Nut is off but it's locked on still. That key I can see in the slot. Do I punch that out somehow?

[@AlvinDedeauxFlyFishing]

If it hasn't been taken off before it can be tough, try hitting it a few times.

[@tegdejonge]

Unbolted my foot. Sleeve is attached still. Does that happen from time to time. I tapped it with a dead blow won't budge

[@AlvinDedeauxFlyFishing]

On the older ones the sleeve is held in with 2 bolts on the side of the foot.

[@williamknight7040]

Alvin, when you run in salt water, how do you flush it out with fresh water?

[@AlvinDedeauxFlyFishing]

Outboard Jets makes a hose attachment.

[@tegdejonge]

Alvin what is gap tolerance supposed to be between liner and impeller? If I'm hitting slightly just file impeller (very) lightly?I took shim from top. Now seem to have a lot of gap

[@AlvinDedeauxFlyFishing]

I think it's supposed to be 1/32. I learned a trick from the folks at outboard jets. They said to tape 2 business cards to each blade before you put the sleeve and foot back on. Tighten it up and the cards will make sure that the liner is aligned with the impeller. Once you start it up the cards will come out. There is a little play in the foot and it can get out of alignment with the impeller.

[@user-ur5hv6yn8k]

The leading edge of the impeller should be 1/32 , the clearance between the impeller and wear ring should be .015 inches

[@DC-xv8pt]

Hey Alvin, Is moving washers from one side of the impeller to the other "shimming"? I'm new to pumps and my pump doest have the power it should, I've been told. I've heard people talk about shimming the impeller due to lost power but I'm unclear as to what that means... Thanks Alvin keep the videos coming.

[@AlvinDedeauxFlyFishing]

Yes that is what it means. Good luck!

[@edwfd356]

Where can I get a transom bracket for a jet on that boat

[@AlvinDedeauxFlyFishing]

The bracket on that boat came with the boat. Hog Island Boatworks make them.

[@acurarl9929]

Will a polished impeller make the boat faster or slower then a stock rough ish impeller?

[@AlvinDedeauxFlyFishing]

Not really sure. Seems like a lot of work so it must help.

[@acurarl9929]

@@AlvinDedeauxFlyFishing just some ppl say faster some say slower. Some say more bite out the hole because more surface tension/ gripping water an less top speed because surface tension/gripping water. Easy/fun day project over the winter. Have all the tools. Just don’t need more hole shoot just wouldn’t mind another few mph up top.
