How to change a waterpump on a Yamaha outboard motor 

Very nice, especially the part about rotating the shaft clockwise to seat the impeller in the housing. Thanks man!!!

Thank you! You helped replace the impeller on the boat we got. It hasn't ran in 3years.

Been learning a bunch from your videos, even the really old ones like this. LOL Just did my first lower unit pull, impeller change, and gear oil change on my "new" 86 Yamaha 6hp. Only issue was getting the pick-up tube back into the new bushing on the housing. The impeller didn't have ANY fins left on it, and pieces of the old ones were wedged in the top and bottom of the housing. I used to think these were complicated jobs, but they're pretty simple if you take your time and pay attention. Pumps water like a champ - and even managed to get the shift linkage back together without too much trouble.

Thanks Eric, I got enough info from watching your vid to do a full overhaul of the water pump. I did the "o" ring and s/s plate and s/s cup and gasket along with the impeller. I added some grease on the bolts and a bit here and there. I found it easier to undo the water line on the outside the motor rather than trying to take the hose off the barb inside the motor itself. But without your vid I probably wouldn't have had a crack at it.

Fantastic detail, thank you particularly for explaining how to get the impeller blades to fit inside of the housing.

Thans Eric. Very helpful for my Iimpeller install.

As easy as I thought it would be... Thank you.

Don't forget to mark the position of the trim tab before removing it. Also, it's a good idea to apply a small amount of grease inside the impeller housing before installing it. Good video.

Do you recommend a light grease on the impeller and the inside of metal ring that goes over it? Whenever I get a new motor they are always chipped up or cracked. Maybe some white lithium or something. Thank you

I so appreciate your videos.. thanks

Thanks for the informative video. Seems to be just like every other brand I’ve had

Great video - succinct and detailed explained

I bought a boat with a Yamaha 90AET from around 1985. I know it's an older model but is it pretty much the same engine and lower unit (except voor the autolube part)?

Thank you, this is the first video I see on changing the pump, very detail and informative, tnx Budd!

excellent video. thanks

So, I didn't see what you were detaching right after dropping the lower unit. It appeared to be the hose (water line)? What about the shift rod? Does that just slide off? I'm getting ready to drop mine right now. (dropped it and it's good).

Thanks you for the vidéo God bless you

great video

Well done video anyone can follow.

Where does the damper gasket fit?? It a black gasket and was with my impeller kit.

Good video thank you very much

I have a 9.9 with this problem. Can this be dont with the motor on the pontoon? Do u have tontake the propeller off?

Would this be the same with an 87 Yamaha pro 50lh ?

Is this the model with gear shift on the tiller?. Do I have to disconnect anything in the engine to drop the leg? Cheers 👍

Very good mate

Thanks!

What year is this motor? I have an 86 50ELJ and apparently I need to disconnect the shift linkage. But every video I've seen, noone even touches that linkage.

hey mate, i have a 2005 yamaha 70hp 2 stroke oil injected and I think i have a slight starting issue, takes about 30 seconds to a minute of cranking to finally get it to splutter then after that it will fire, seems to idle fine and once the motor is warm it starts absolutely fine, just curious if you would be able to shed some light in what to look at for just the starting issue, i see on your channel that all your 2 stroke just basically fire straight away

2020/09/03 -- Can you do a Rebuild Video . for a Yamaha 25-30-40 Lower Unit! .?

Eric, is there a rubber grommet at the pump end of the water tube that seals the tube into the plastic/delrin pump housing? On my 00 60 the pump housing is tapered and currently it has no grommet or seal. Was curious if it was a missing part on mine.

Get info you just save our family trip this weekend

Hey, I have a similar Yamaha. C40tlrw. I have a problem where it runs great but then will start losing power and slow down, I bring the throttle back down and then I can go fast again for about a minute and a half. I had the carbs done to no avail. I found out it was an over heating issue because I removed the temp switch and it didn’t have the issue. It pees great from the water hole, and I pulled the water jacket and everything off down to the pistons to see if there was salt build up and it was perfectly clean. There is a water leak up near the top of the leg where it swivels. Any suggestions?

I just buy the water pump kit.It is only a few bucks more than the impeller.Probably one of the easiest to work on,Yamaha uses a rotary shift,so no linkage rods and such.I replace impeller every 300 hrs,plus the thermostat.Local dealer(stealer)wanted 379.00 to do those-ripoff!

Same as a 9.9? I just did mine 4 stroke 2010 and now it won’t start

Right on!!!!

I just did this on my out oars and now its starts up in gear. How do i fix this?

Very noisy back ground Good information

Are there no orings, seals or gaskets?

1:12 What's the purpose of that tube there? Great tutorial. Others had forgotten to show the bolt under the anode. I struggled with the lower unit until I found your excellent take down. Thanks a mil.

Confused on the reinstalling the rod next to the tube/plug?

Eric I'm having an alarm issue.The pee is shooting water just fine and I see theprevious owner did change the thermostat at some time. It's a continuous alarm and after letting it cool down for a few minutes it fires up and seems to run fine and no alarm. Any idea what this could be?Thanks for any help. BTW I have Yamaha 40 hp 2 stroke 1986 model. Again thanks

Whats the name of the part just above the propeller that you took off before removing the lower part of the motor.

for yamahas, there is typically a plastic collar with a metal ring over it that sit just above the impeller inside of the pump housing

Hi, really good video. Can you advise, what the small hose is for that needs to be disconnected and reconnected at the bottom half of the leg when separated? Does it vent any where, or does it act as a pickup for water? As mine is pretty well salted up. Just need to know if it goes anywhere??? Thanks. Tony

I did this and now why boat won't go into reverse or forward while motor is running and the lever moves when motor is dead...I didn't disconnect anything, what is going on?

So you don't have to undo a gear linkage?

Are the gaskets not important?

👌Thank you!

what do you recommend using for grease?

Hi i need some help with my yamaha. Can u ?

What’s the rubber tube closest to transom side anyone?

There's no steering linkage on this motor?

I made it with Avasva handbooks !

Will a Yamaha 2019 lower unit fit on a 1993 25 hp?

Hey Eric, I replaced my impeller the other day..fixed carbs, thanks to you...and now it fires up but doesn't shoot water out the telltale, any ideas boss ?

so when you get to the point of putting it back together i cant understand what your saying over the cars. what did you sat?

My pump works and doesnt work. On and off . Not trustable lol what could be the issue,

What does the black tube that you disconnect to detach the lower part of the shaft do. Mine is disconnected and capped on my engine.

Does the prop have to be off to do this?

Is he changing the impeller or water pump??

Do you not have to drain the oil from the lower unit to replace the pump?

Is it the same to do for a 2000 Yamaha 4 stroke

how to check and change engine oil ?

I’d done replace my water pump on my Yamaha 2 stroke 200 it still not pumping

30 € the turbine in French !!!!!

mate ...the first thing ya wanna do is take it out of gear,,,

Great video but am I the only one that saw the impeller cover put on backwards?

1:22 I loved the part about putting the lower unit on the ground to scratch up the finish and promote corrosion

Dude let people know about the gear rod disconnect

Says nothing about inspecting the base plate or cup.

Something about (indistinguishable...) " this tube" upon removing the lower unit ?? Totally lost me.

Screws are for wood, bolts for metal. Rather than rotate the flywheel, leave the prop on and just simply rotate that instead. Good job otherwise !!
