Note the Yamaha B90 water pump impeller is included in the water pump kit, or it can be purchased on its own here: www.boats.net/product/yamaha/...
Learn how to change the water pump on a Yamaha outboard motor in this video from Boats.net. We’re going to remove the lower unit, disassemble the water pump, and use a Yamaha 90HP outboard water pump kit to make our repair.
We’ll show you how to remove the lower unit and then take your water pump apart. On our motor, the impeller was torn, so we’re going to replace it along with the other gaskets included in the Yamaha 90TLR water pump kit. When you replace the upper water pump housing, be careful not to overtighten the bolts. The housing is made of nylon and can crack if overtightened.
Once we replace the water pump on our Yamaha outboard, we’ll show you an easy way to get the lower unit back on your motor and reinstall the trim tab.

Very good video, two points should be added. There is a small tab on top of the SS cup. This tab needs to line up with the corresponding dimple on the underside of the water pump housing to keep the SS cup from rotating on the shaft after assembly. Also it is easy to miss line up the gear shift spline while placing the lower housing back an to the motor. Make sure the gear shift spline actually gets inserted into the upper linkage or the motor will not shift after assembly. Easy to miss this point if you are not paying attention. Thank you again for the excellent video

Good job not mentioning the gasket above the metal plate. Or how youre supposed to line up tge cup with your housing.

Thank you so much for the video. Exactly what I needed to get my boat running again.

@jamescross5013 5 лет назад

wow... what a great video. Garrett, you are a pro, and thanks for getting rid of the fear factor for me... I've done cars but boat engines were a phobia...you make it look so easy.

@BoatParts 5 лет назад

Glad I could help, James! Really anyone can do a water pump or an impeller; if you've been under the hood of a car, you have a head start. Glad we could help get you started. Lots more Yamaha videos to come, stay tuned! -- Garrett

Tks for an excellent instruction. I'm having a problem with my 2005 70 hp Yamaha that was tuned up and lower unit dealt with . When turned on at neutral or at low trolling speed, alarm sounds off and doesn't stop until I rev up the engine. Noticed that the water flow off the pee hole is weak initially but gets stronger when revving up. Any ideas of what it could be? Mechanic back in and could not find any major issues. Would appreciate a reply

@micheledifeo4938 2 года назад

great video, the water from my engine comes out in flots. I have also changed the impeller and the gaskets. Mercury orion 60 hp from 2016

Thanks would the process be the same for a Yamaha C40PRLV 1997, My warning buzzer sounds after about 10 minutes under load but looks like plenty of water coming out of the top.

@byronakhavi953 2 года назад

Nice reference video, You did not note cleaning the bolts, using Loctite 572 on the bolt threads, apply grease to the water tube and impeller fins. The unit should be in neutral gear and tested by turning the prop shaft freely to confirm that it is in neutral. The shifter has a mark that the pin needs to match to confirm neutral. You should take that prop off for this job. Lastly, a slight wiggle on the shifter can help with installing the unit. People should be told to consult their service manual and use this video as a reference. Not a guide for their motor. A brass hammer should be used for that impeller key but the position it should be in is correct. A little penetration oil and using a dull chisel to hit the key at the bottom will index it out. Then it can be tapped out. Using a punch is difficult and it should be a brass punch.

@Apelpeach 4 года назад

The question I have. How serious is it that I recover the small rubber pieces that broke off, of the water pump impeller while running the engine, I had water hooked up to try and get it to pump, it would not pump, so I replaced the impeller pump, It pumps good now, but I'm worried where the rubber pieces went.

@jkg6211 3 года назад

Remove the bolt holding the two water intake screens off the lower... they're probably in there.

Great video. Only problem is around 8:18 they forgot to mention the second gasket that gets installed between the plastic housing and the metal plate.

@MrVerno1960 3 года назад

Thanks for pointing that out! I had the same issue and had to remove the impeller (which is pretty tight) to install the second gasket.

@Robert-uq5ew 3 года назад

@condor5635 4 года назад

The metal impeller housing had a hole in it at 8:40 - Is there not some alignment required for that hole? Mine came out attached to the plastic housing so I never had them separated in the first place but I did notice the hole in the metal and wondered if it's placement is critical. Great video. Thanks for posting

What's the piece that goes across behind the cup? I have a 100 4 stroke and mine is corroded and cracked and trying to find out what it is it has a rubber then the alloy

@mikescorsone8172 4 года назад

That is the damper seal guide and the damper seal -- commonly overlooked but should be replaced too if the guide part is corroded out like the one in this video. I just replaced this on my F90 Four Stroke - go to boats.net and look at the parts breakdown for your motor, I believe the parts you will need is DAMPER, SEAL 688-45375-00-00 and GUIDE, SEAL DAMPER 663-45376-00-94 but check to make sure. Best of Luck!

I replaced the water pump as instructed but the new pump isn’t pumping very much water out the tell tale. What could be wrong?

@earlprice7200 Месяц назад

If it's Installed correctly and everything is in good shape. The pump may be doing what's supposed to. Take the plastic fitting out the end of the water line make sure it's clear. If that doesnt do the trick ...You may have some circulation issues...blockages like sand or corrosion build up... I'd start by pulling the thermostat housing off and make sure it's opening properly and also look for evidence of sand and corrosion obstructions. !
