Installation Guide

  1. Preparation: Disconnect the fuel line and tilt the engine to access the lower unit. Gather necessary tools including socket wrenches, screwdrivers, and a torque wrench.
  2. Remove Lower Unit: Drain the gear oil completely using the drain screws. Remove the bolts securing the lower unit to the mid-section and carefully separate the lower unit.
  3. Water Pump Disassembly: Remove the old water pump housing by unscrewing the mounting bolts. Carefully extract the old impeller, wear plate, cup insert, and seals.
  4. Clean Components: Thoroughly clean the water pump cavity and inspect for corrosion or damage. Ensure all mating surfaces are smooth and free of debris.
  5. Install New Water Pump Parts: Insert the new key onto the driveshaft, then slide the new impeller (lubricate blades with glycerin or soapy water) onto the shaft with blades facing the correct direction. Install the new wear plate, cup insert, O-ring, and water seal per the service manual.
  6. Reassemble Water Pump Housing: Position the new housing over the assembly and secure with the provided bolts, torquing to manufacturer specifications (typically 7–10 ft-lbs).
  7. Replace Filters: Locate and remove the old fuel filter and oil filter from the powerhead. Install the new fuel filter (observe flow direction arrows) and spin on the new oil filter hand-tight plus 3/4 turn.
  8. Thermostat Replacement: Remove the thermostat cover, extract the old thermostat and gasket, then install the new thermostat (ensure correct orientation) with the new gasket. Reinstall the cover and torque bolts evenly.
  9. Anode Installation: Remove the old sacrificial anode from the lower unit and clean the mounting surface. Install the new anode securely to prevent galvanic corrosion.
  10. Reinstall Lower Unit: Apply new drain gaskets to both the fill and drain screws. Carefully align the lower unit with the mid-section (ensure the water tube enters the grommet) and secure with bolts, torquing in a cross pattern.
  11. Refill Gear Oil: Using the included gear oil pump, fill the lower unit with the manufacturer-recommended gear oil until it overflows from the top vent hole. Install the top screw first, then the bottom drain screw with new gaskets.
  12. Final Check: Reconnect the fuel line, lower the engine, and run it in a test tank or on the water. Verify strong water stream from the tell-tale, check for leaks, and confirm smooth operation.

Troubleshooting & FAQ

Q: How do I confirm this maintenance kit fits my engine?
A: Cross-reference your engine model and year with the compatibility table above (F20A/F25A 1998–2009, F25D/F25HP DEHTL/DETL/DMHL 2009–2017). You can also verify using the Yamaha serial number guide or consult your engine's parts diagram for OEM number 6G8-W006A-00.

Q: How often should I perform this maintenance service?
A: Yamaha recommends replacing the water pump impeller every 2–3 years or 200–300 hours of operation, whichever comes first. Filters, thermostats, and anodes should be inspected annually and replaced as needed based on condition.

Q: What are the signs that my water pump or filters need replacement?
A: Weak or absent water flow from the tell-tale, engine overheating, reduced performance, hard starting, or visible impeller damage are common indicators. If your engine is running hot or you notice performance issues, inspect and replace these components immediately.

Q: Can I install this kit myself or do I need a professional?
A: Installation requires moderate mechanical skill and familiarity with outboard lower unit service. If you are comfortable with basic tools and following a service manual, DIY installation is feasible. However, professional installation is recommended if you lack experience to ensure proper torque specs and alignment.

Q: Does this kit include everything needed for a complete service?
A: Yes, this kit includes the water pump rebuild components, fuel and oil filters, thermostat assembly, drain gaskets, anode, and a gear oil pump. You will need to supply the appropriate gear oil separately.

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?

Perfect comforter for the price and as fluffy as I had hoped.
Color: Grey, Size: Queen
I was looking for a blanket that was nice a fluffy and had a decent thickness to it as well. I already have a weighted blanket underneath so I didn’t need anything heavy. This blanket is wonderful for the price and puffs up very nicely after you take it out of the package. No weird smells to it and it is very warm at night. My cat actually loves it to much he has moved from his own space to sleeping in on the bed because it’s so soft. It looks great on the bed and fits well with my queen size bed. Qualify is what you would expect from a blanket in this price bracket. What I like about that is that if my cat continues to make biscuits (even after clipping his nails) and pulls up some of the blanket fibers, I have no issues spending another $35 ish to buy another one once this one has had enough of the kitty claws. Sorry that was rambling a bit. Long story short. Fluffy blanket, very warm, breathes well, feels great to wrap yourself in after a long day. Sleeping better with this comforter than I ever have. Good luck out there. Enjoy.

Great set of sheets
Color: Blue Pinstripe, Size: Twin
These microfiber sheets are incredibly soft and comfortable, especially for the price. I purchased the blue and white set for my daughter’s bed, and she loves them. The colors are bright and exactly as pictured. They fit the mattress well, don’t slip off the corners, and wash up nicely without pilling or fading. The brushed microfiber feels cozy and lightweight, making them great for year-round use. Overall, a great value and I would definitely buy another set.

Bold Colors, Great Quality, and an Amazing Price - Perfect Everyday Sheets
Color: Black, Size: Full
The Amazon Basics lightweight bed sheets have been such a great buy for my boys’ bedrooms. They come in a wide variety of colors, which made it easy to match each room’s style — and the colors stay bold and vibrant even after multiple washes, which honestly surprised me. The quality is excellent for the price. The fabric stays soft, doesn’t pill, and holds up well to frequent washing (a must in kids’ rooms!). Each set includes a fitted sheet, flat sheet, and two pillow shams, which makes the value even better — most sets at this price point don’t include that many pieces. Overall, these sheets are affordable, durable, colorful, and comfortable. I loved them enough to buy them in multiple colors, and they’ve held up beautifully. A fantastic budget-friendly choice for any household.

I really like these sheets. They are soft, lightweight, and fit my twin mattress perfectly. The lavender color looks beautiful in person and they feel comfortable to sleep on. After washing, they still looked nice and didn’t wrinkle much. Great quality for the price!
