Installation Guide

  1. Disconnect the spark plug lead and remove the lower unit from the engine. Drain all gear oil using the drain plugs.
  2. Remove the old water pump housing by taking out the mounting bolts. Carefully pull the housing off the driveshaft.
  3. Clean all mating surfaces on the lower unit and driveshaft housing. Remove old gasket material and inspect for corrosion or damage.
  4. Install the new impeller onto the driveshaft, ensuring the key aligns properly. Apply marine grease to the impeller blades for easier installation.
  5. Position the wear plate and insert cup into the new housing. Ensure all seals and O-rings are properly seated.
  6. Slide the new water pump housing over the driveshaft and impeller. Rotate the driveshaft clockwise to help the impeller blades fold into the housing.
  7. Secure the housing with the provided bolts, tightening in a star pattern to manufacturer torque specifications.
  8. Replace the thermostat in the cylinder head if accessible during this service. Use a new gasket or seal as provided.
  9. Install the new anode in its mounting location. Ensure proper electrical contact with the engine block.
  10. Replace the fuel filter and oil filter according to their respective mounting locations. Use new drain gaskets on all oil drain plugs.
  11. Refill the lower unit with fresh gear oil using the included gear oil pump. Install drain plugs with new gaskets and tighten securely.
  12. Reinstall the lower unit onto the engine, reconnect the spark plug lead, and test the cooling system by running the engine in a test tank or on-water.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my specific Yamaha engine?
A: Cross-reference your engine model and year with the compatibility table above. You can also check your engine's parts diagram using your serial number via the Yamaha Serial Number Guide linked in the Compatible Engine Models section.

Q: How often should I replace the water pump impeller and service the cooling system?
A: Yamaha recommends inspecting the impeller every 100 hours of operation or annually, whichever comes first. Replace if blades show wear, cracking, or loss of flexibility to prevent overheating.

A: Common symptoms include reduced water flow from the telltale (pee hole), engine overheating alarms, steam from the engine, or visible impeller damage during inspection. Address these issues immediately to prevent engine damage.

Q: Can I install this kit myself or do I need a mechanic?
A: If you have mechanical experience and the proper tools, you can install this kit following the guide above. However, professional installation is recommended to ensure all seals are correctly positioned and torque specs are met.

Q: Does this kit include everything I need for a complete service?
A: Yes, this kit includes the water pump components, thermostat, fuel filter, oil filter, anode, drain gaskets, and gear oil pump. You will need to supply fresh gear oil and basic hand tools.

Works for foot psoraisis
Size: 2 pairs black L
Got these for work (service industry) to reduce issues with psoriasis and blisters while putting on 20k+ steps a day. Over time the wounds healed and I could work without so much pain. I now don't use them all the time like I used to, only when a new lesion or blister appears, too prevent a breakout. Tip: if you're not in full breakout, wear thick socks under these as a barrier to friction.

Work well but run small
Size: 1 pair black L
They do seem to run a bit small. I bought them for my bf but snagged them from him because I couldn’t resist! I’m about a W8/12 and they were just a little big but unlike others, I just put them on while sleeping and didn’t walk around with them. If you’re just planning on that, they did a great job at sloughing and moisturizing 😎

Good socks they work.
Size: 2 pairs black L
I normally wear size 13&half to 14 men's, and these fit me ok. They sit just below the ankle. They can get a little tight for me so you should look out for that if you are on the thicker side. But they work as advertised and help moisturize your feet. I recommend wearing them if you're going to just be hanging around home for a bit in one spot as they can be a little slippery to walk in if you go fast. Would not recommend going up and down stairs.
