  4. Access the Pump: Locate and remove the bolts securing the water pump housing.
  5. Disassemble Old Pump: Remove the old housing, impeller, wear plate, and gaskets. Note the orientation of the old parts.
  6. Clean Surfaces: Thoroughly clean the mating surfaces on the gearcase and driveshaft.
  7. Install New Components: Install the new gaskets, wear plate, impeller (rotate shaft clockwise), and seals from the kit.
  8. Reassemble Housing: Apply a light coat of marine grease to the inside of the new housing and install it over the impeller. Secure with bolts.

  10. Refill and Test: Refill the gearcase with fresh oil. Reconnect the battery and start the engine in water to verify a strong water stream from the tell-tale outlet.

Troubleshooting & FAQ

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

A: The most reliable method is to match your engine's serial number to the ranges listed in the compatibility tables. The serial number is typically found on a tag on the transom bracket. Use our linked serial number guide for help locating it.

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

A: Common indicators include the engine running hotter than normal, an intermittent or weak water stream from the "tell-tale" outlet, and visible cracking or damage to the old impeller upon inspection.

Q: How often should the water pump impeller be replaced?

A: For preventative maintenance, it is highly recommended to replace your impeller every 1-2 years or every 100-200 hours of operation, depending on usage and water conditions (saltwater vs. freshwater).

Tasty good for you beverage
Flavor Name: Black Raspberry, Size: 17 Fl Oz (Pack of 12)
So refreshing and tasty. I gave up Pepsi due to the caffeine and found these so satisfying. The taste is great and just enough fizzy! A great value and the bottle size is good for more than one if you wish. No sugar load and theres vitamins too. The case is 12 bottles and had no leaks or damage! Quick delivery too!

Great-Tasting Protein Shake With Fresh Product Dates and Excellent Nutrition
Flavor Name: Chocolate, Size: 11 Fl Oz (Pack of 12)
I picked up this Premier Protein chocolate shake 12-pack mainly as a convenient daily protein option, and overall the quality has been excellent. The chocolate flavor tastes very good without being overly sweet, and the texture is smooth compared to many protein drinks that can feel chalky or heavy. The 30 grams of protein also make it very practical for quick meals, post-workout use, or busy days when preparing food is not convenient. One thing I appreciated is that the product arrived with fresh expiration dates, which is important when buying protein drinks in bulk. The packaging was also in good condition, and the bottles were easy to store and carry. The nutritional balance is another strong point, especially with the added vitamins and minerals included without extra added sugar. Compared to many other ready-to-drink protein shakes, this one feels lighter while still being filling and satisfying. In terms of value for the money, it feels like a very good purchase considering the quality, nutrition content, convenience, and freshness. Overall, a high-quality protein shake with excellent taste, fresh product dates, strong nutritional value, and very good everyday convenience. It can also be mixed with other flavors.
