Installation Guide

  1. Safety First: Disconnect the battery and ensure the engine cannot start accidentally. Disconnect the shift linkage before proceeding.
  2. Remove Lower Unit: Remove the mounting bolts that secure the lower unit (gearcase) to the engine's midsection and carefully lower it.
  3. Access the Pump: With the lower unit removed, locate and unbolt the water pump housing (typically 4-5 bolts).
  4. Disassemble Old Pump: Remove the old housing, impeller, wear plate, gaskets, and seals. Take note of the orientation of the old impeller's fins.
  5. Clean Surfaces: Thoroughly clean the mounting surfaces on the driveshaft and lower unit to remove any old gasket material or corrosion.
  6. Install New Components: Install the new water pump gasket, outer plate, and Woodruff key on the driveshaft.
  7. Install Impeller: Slide the new impeller onto the driveshaft, rotating it clockwise to bend the vanes correctly as it enters the lubricated housing.
  8. Reassemble Housing: Secure the new housing with the new bolts and tighten them to the manufacturer's specified torque.
  9. Reinstall Lower Unit: Carefully guide the lower unit back into place, ensuring the driveshaft, shift shaft, and water tube align. Re-secure the mounting bolts.
  10. Final Checks: Reconnect the shift linkage and battery. Test the engine on a water supply (using "ear muffs" or in the water) and confirm a steady stream from the tell-tale outlet.

Troubleshooting & FAQ

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

A: The most reliable method is to cross-reference your engine's model and year with the detailed lists in the 'Compatible Engine Models' section. Verifying the OEM part number (63D-W0078-01-00) against your service manual or existing part also ensures a correct match.

Q: What are the common symptoms of a failed water pump impeller?

A: Key signs include the engine overheating at idle or low speeds, a weak or intermittent water stream from the "telltale" outlet, or finding brittle, cracked, or missing vanes on the old impeller during inspection.

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

A: As a crucial part of preventative maintenance, we recommend replacing the impeller every 1 to 2 years or every 100-200 hours of use. This can vary based on operating conditions, especially in saltwater or sandy/silty environments.

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.

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.

Perfect for Adding Privacy to a Piano Studio
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
I Ordered the 2 Panel version which is way too big for my needs... that's on me. So keep in mind that the picture shows a fabric made for two panels only being used on one and hence it is not pulled tight; it would pull tight and not be so wrinkly if it was set up properly as two panels. The metal pools that make up the panels seem to be well made, stable, and of good quality. They were very easy to put together and they stand up tall with plenty of height. The appearance of it with the fabric on it isn't as elegant as it could be, but it still looks good enough. The material is plenty solid, not allowing light through it, and thereby making a solid barrier. I am using it to block the view out the studio door when a student is sitting at the piano to avoid distractions from the hallway. It will allow a student to enter the studio with our distracting the student who is at the piano.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room. The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams. The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.

It's 2 panels holding 1 big privacy screen. Can't use as 2 separate 4' panels, but works great.
Size: 2 Panel 8FT W
This 2 panel privacy screen works well. Assembly was very straight forward, with easily labeled tubes. My son and I had it together in about 10 minutes, which was probably 3 minutes of me telling him to quit playing around and hand me the parts. It feels very sturdy, not likely to fall over or anything. The material fits well, with the Velcro being very strong. Measurements are all very accurate, with all pieces attaching properly. We have a similar privacy screen at work that we have to try and stretch out because the top and bottom Velcro doesn't fit quite right... this model does not have any issues though. The material is thin and light weight, but solid black so that you can't see anything through or behind it. I definitely think it's a great deal for the money. What I think would have given it 5 stars though, is if you had 2 totally separate 4' panels instead of 2 panels with one big screen. It really wouldn't cost any extra to make it so that the screen was in 2 pieces and you could use it as 2 separate panels instead of having to use it as one big panel. It says 2 panel folding privacy screens, but it's really one big one that folds in the middle.

Trouble hanging

This was easy to assemble, just the right size. The only thing was the way it was hung on wall, very hard to measure the right height.
