Installation Guide

Professional installation is recommended. The following are general steps for replacing the water pump assembly. Always consult your service manual for detailed instructions and torque specifications.

  1. Disconnect the battery and shift the outboard into neutral.
  2. Drain the gearcase lubricant from the lower unit.
  3. Remove the bolts securing the lower unit to the upper casing and carefully lower it.
  4. Remove the bolts on the water pump housing to access the old impeller. Note the orientation of the old parts.
  5. Clean the housing and surrounding area, removing any old gasket material or debris.
  6. Install the new base plate gasket, outer plate, insert cup, and gaskets.
  7. Slide the new impeller onto the drive shaft, ensuring the key is in place and the vanes are oriented correctly (typically clockwise).
  8. Replace the housing, O-rings, and bolts, tightening them to the manufacturer's specified torque.
  9. Reinstall the lower unit, ensuring the driveshaft, shift shaft, and water tube are properly aligned.
  10. Refill the gearcase with new lubricant and test the engine using a water supply (flusher) to confirm proper water flow.

Troubleshooting & FAQ

How do I confirm this kit fits my engine?

First, check your engine model and year against the "Compatible Engine Models" table above. We strongly recommend using the linked Yamaha Serial Number Guide to verify your engine's details. Cross-referencing the part number stamped on your old components with our "Part Number Cross-Reference" table is the best way to ensure an exact match.

Does this fit the Yamaha F130 model?

While one of our sources indicates compatibility with the F130 (2021–Up), this is not confirmed across all OEM documentation. We advise F130 owners to visually inspect their existing water pump components and part numbers before ordering to guarantee a match.

What are the signs of a failing water pump impeller?

Common symptoms include the engine overheating at idle or low speeds, a weak or inconsistent stream of water from the "tell-tale" outlet, or a complete lack of water flow. The overheat alarm may also sound.

How often should I replace the water pump impeller?

As a critical preventative maintenance item, most marine mechanics recommend replacing the impeller every 1-2 years or every 100-200 hours of operation, whichever comes first. This interval can be shorter if you frequently operate in sandy or silty water.

OEM vs. Aftermarket?

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.

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

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.

Worth it!
Flavor Name: Coconut, Size: 25.4 Fl Oz (Pack of 1)
Compared to Torani syrups I prefer this one for my coffee in the morning. It’s soft, smoother and tastes delicious combined with cream. You get a lot for the price you pay and it lasts.

Great upgrade compared to others
Color: Rechargeable with Storage Stand and Box - Black
This frother is far superior to other hand held versions we’ve owned. The attachments are much sturdier and don’t bend as easily (which made the others we’ve purchased quite useless). Rechargeable battery seems to last longer and provides plenty of power even on the lowest setting. The little wisk easily whips up eggs for a morning omelette and frothing cream and mixing powder into drinks are super easy with the other attachments. Finally, the stand is actually sturdy and balanced enough that it doesn’t easily tip over.

Three froth/blend options, rechargeable, comes with container
Color: Rechargeable with Storage Box - Silver, Color: Rechargeable with Storage Box - Silver
I watch a gentleman online who always talks about how in his 40 years he didn’t know x, y, z, and ends with “ain’t no way.” He made this 3-ingredient — 4 with ice— iced coffee, and used a handheld frother, so after shopping for ingredients, I went in search of a frother. What I liked about this one is that it’s not battery operated, but instead is rechargeable. It comes with three attachment, one of which I can use for cake batter, whipping up eggs, making homemade whipped cream, and also sauces and gravy. It also has a case so I am storing it with my coffee paraphernalia. It has three settings and I used the high setting. As you can see it really froths up the ingredients. I’m very pleased with my purchase and thought about all the times I need a slurry of water and cornstarch to thicken soups and stews. I don’t know the charge life yet, but so far, so good. What you see in the cup is 2 tablespoons of sweetened condensed milk, 3 teaspoons of instant espresso, and 2 ounces of water. Then you add the ice and your creamer, half-and-half, or barista lover’s oat milk, and you’re done. Not too bad, as my grandpa used to say.

Great product
Color: Rechargeable with Storage Box - Black
It’s great! Very powerful, even on low speed. Mixes fiber, and powdered mix-ins very well as well as frothing milk. Nice sturdy little case to keep the components in. Stays charged for a long time.
