Installation Guide

  1. Safety First: Disconnect the battery and ensure the engine is securely mounted in an upright position.
  2. Access the Lower Unit: Drain the gearcase oil. Remove the bolts securing the lower unit (gearcase) to the engine's midsection.
  3. Remove the Lower Unit: Carefully lower the gearcase away from the engine. The driveshaft will disengage from the powerhead.
  4. Expose the Water Pump: The water pump housing is located on top of the gearcase, surrounding the driveshaft.
  5. Disassemble the Old Pump: Remove the pump housing bolts and slide the housing off the driveshaft. Note the orientation of the old impeller vanes.
  6. Remove Old Components: Take out the old impeller, wear plate, insert cup, and any gaskets or seals. Clean the mounting surfaces thoroughly.
  7. Install New Components: Place the new wear plate and gasket onto the gearcase. Slide the new impeller onto the driveshaft while turning it in a clockwise direction to bend the vanes correctly.
  8. Install New Housing: Lubricate the inside of the new insert cup and housing. Slide the new housing assembly over the impeller and align the bolt holes.
  9. Secure the Housing: Tighten the housing bolts to the manufacturer's specified torque.
  10. Reinstall Lower Unit: Carefully guide the driveshaft and water tube back into position and bolt the lower unit back onto the engine. Refill the gearcase with new oil.
  11. Test the System: Reconnect the battery. Start the engine using a water supply (flushing attachment) and verify a steady stream of water is exiting the tell-tale port.

Troubleshooting & FAQ

How do I confirm this fits my engine?
The most reliable method is to match your engine's model and year to the compatibility table. Please cross-reference the OEM part numbers listed with your engine's original parts diagram if you are unsure.

What are the signs of a failing water pump?
Common symptoms include a weak or intermittent water stream from the "tell-tale" outlet, the engine overheating at low speeds, or a high-temperature alarm sounding on the console.

How often should I replace the water pump impeller?
As a general maintenance guideline, the impeller should be inspected annually and replaced every 1-2 years, depending on usage (hours) and operating conditions (saltwater vs. freshwater).

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.

Quality No Show Socks That Are Comfortable and Durable
Size: Large, Color: (100) White / White / Black
These Under Armour no show socks are great for everyday training and casual wear. The cotton blend feels comfortable and they stay in place throughout the day. Getting six pairs in a pack is solid value for a quality brand. They hold up well after multiple washes and the no show style works great with most athletic shoes. A reliable go-to sock.

Comfortable
Size: Large, Color: (001) Black / Black / White
I recently picked up a pair of Under Armour socks, and they’ve quickly become my go-to choice for daily wear and workouts. From the first wear, the fit felt snug and supportive without being too tight. The fabric is lightweight yet durable, and it does a great job wicking sweat — keeping my feet dry even during longer runs or intense gym sessions. One of the things I appreciate most is the arch support and cushioning in the right places. It adds just enough padding where I need it, especially under the ball and heel of the foot, which makes a noticeable difference on days when I’m on my feet a lot. The socks also have a nice breathable mesh pattern that improves airflow.

Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.
