  4. Place the lower unit on a workbench. Remove the four bolts securing the water pump housing.
  5. Slide the old pump housing up and off the driveshaft. Remove the old impeller, key, and wear plates.
  6. Thoroughly clean the driveshaft and the pump mounting surface.
  7. Install the new Woodruff key, gaskets, and wear plates from the kit.
  8. Slide the new impeller onto the driveshaft, turning it clockwise to align with the key and seat the vanes.
  9. Lightly grease the inside of the new pump housing and slide it over the impeller.
  10. Align the housing bolt holes, install the new bolts with seals, and tighten them to the manufacturer's specified torque.
  11. Reinstall the lower unit, carefully aligning the driveshaft splines, water tube, and shift shaft.
  12. Secure the lower unit with its mounting bolts and reconnect the battery. Test run the engine with a water supply.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my Yamaha engine?

A: First, check your engine's model, horsepower, and year against the comprehensive "Compatible Engine Models" tables provided above. For additional verification, you can use our Yamaha Serial Number Guide to pinpoint your exact engine model and the corresponding OEM part numbers.

Q: What are the signs my water pump impeller needs to be replaced?

A: Common indicators of a failing impeller include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alarms, or a noticeable drop in cooling performance. A visual inspection during routine service may also reveal cracked, brittle, or worn impeller vanes.

Q: How often should I replace the water pump impeller?

A: As a general rule for preventative maintenance, it is recommended to inspect the impeller annually and replace it every 1-2 years or after every 100-200 hours of operation. Service intervals should be shorter if the engine is primarily used in saltwater or in water with high levels of sand or silt.

Q: OEM vs. Aftermarket?

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?

A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Q: What is your warranty and return policy?

A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.

These things work great for my apple products.
Color: White
Used for apple watch, iphone 15 Pro Max and air pods pro. Have one that was purchased elsewhere and given to me as a gift. Wanted another but was waiting for a price drop that was more in line with my feelings of what is a fair price. Amazon offered them at a decent price so sprung for a second. WHY? They are very stable. Doesn’t feel like it will tip even with my phone on there horizontally. Footprint is very small. I can put the phone both vertical and horizontal and it charges great with both an Ultra 3 watch and an apple watch 11. Can also charge the air pods at the same time. The best part that justifies the price is it comes WITH the watch charger right there on it. You don’t have to lace your own watch cord through some tiny space like some others I have owned. And the apple watch chargers are expensive. Would easily fit in a bag to carry with me. Although it doesn’t fold down for travel. Comes with the USB wall wort and the USB-C cable. C cable plugs into the single outlet on the back of the charging unit. No issues with overheating of devices. I bought the white one. The plastic charging pads for the phone and air pods are a light gray and they look good together and with the white. I just like white, but they have other colors. It also charges my Anker Soundcore rechargable earbuds. It has a white light that comes on when I put my items on the charger. I will absolutely be getting another. Have been buying Anker products for a while. Nearly all have been fabulous. BUT they did have a recall on a 5000 or 10000 mAH portable charging pack. Cannot remember which it was. But amazon notified me about it, even before the recall hit the news. Have had absolutely no problems with either one I have.

Awesome charger!
Color: White
I have a few Anker chargers and this is definitely a favorite! I usually charge my phone and watch simultaneously so I got this one for traveling. I love the way my phone stands on the charger. It’s great to check the time when waking up. It charges my watch very quickly so I can put it back on before falling asleep. The fast charge and compact form is great for traveling. It’s also easy to plug in and charge my phone, watch, and earbuds at home. Anker chargers are my favorite. I’ve never had an issue with them and they work forever.

Another excellent Anker product
Color: Black
I always start my peripheral search with Anker. As all my Anker equipment are, it’s solid, compact and works as promised. If I get really picky, when I have my Air Pods charging, the band of my Apple Watch takes some extra effort to tuck in above it (a little more height would be appreciated, although it would work against its compactness). That’s a really minor gripe. I love that the magnet is strong and that the orientation can be changed from landscape to portrait without removing it from the mount. It will fit into a suitcase easily and the AC adapter is small. I couldn’t be happier with it!

The only MagSafe charger you’ll ever need..!!
Color: Black
Yet another AWESOME charger from Anker..!! Unlike cheaper MagSafe chargers, this one almost reaches out and grabs your phone when you’re attaching it for charging.. Holds your phone securely for bedside mode at night and there’s no need for a 25W charger that’s more expensive.. Just a perfect size and works well… looks no further…. This is the bedside charger to get..!!

Actual, honest-to-goodness fast charging
Color: Black
After unsuccessfully buying two different so-called "fast" chargers that completely lied about their charging ability, specifically for the Apple watch, I finally bought this one. What a world of difference! I have an Apple watch ultra, which is fantastic on battery life, and I appreciate that I can actually wear it while I sleep. I have to charge it about every day and a half, which means that sometimes I need to top it up while I'm at work. (Alternatively, I could be a slave about charging it every day at home, but part of the reason I switched to the Ultra is to not have to be that obsessive about charging.) Anyway, I needed a good charger at work. I ordered one that claimed to be 5W watch charging, and it blatantly lied. It took over an hour to get about 20% of a charge. I ordered another, similar results. This one is night and day different. My watch will fully charge at the posted speeds Apple boasts about with fast chargers. If it's running a little low during the day, I can pop it on the charger for 20-30 minutes and have enough juice to last through my hour+ swim workout, no problem. The phone charger is fast, too, and if you use a magsafe case, it has a very firm hold. Without a magsafe case, your phone may drop off the charger (mine did), which is frustrating. Since I have another magsafe charger at home, I just bought a new case (they're cheap) and now I'm super happy with this. The contact charger on the back will work to charge your phone (or a second phone) or earbuds, too. Very happy with this purchase. It's a bit pricier than the cheapo other brands, but it actually freaking works and charges quickly. It's worth the money.
