Installation Guide
- Preparation: Disconnect the fuel line and flush the engine cooling system. Remove the lower unit according to your service manual.
- Access Water Pump: Remove the bolts securing the water pump housing to expose the old impeller and components.
- Remove Old Parts: Carefully extract the old impeller, wear plate, insert cup, and gaskets. Inspect the pump housing for damage or corrosion.
- Clean Surfaces: Thoroughly clean all mating surfaces, removing old gasket material and debris. Ensure the pump cavity is free of sand or salt buildup.
- Install Insert Cup & Key: Place the new insert cup (63D-44322-00) into the housing and install the drive key (90280-03024) in the driveshaft slot.
- Lubricate & Install Impeller: Apply marine grease to the new impeller (6H4-44352-00) and insert it with blades oriented correctly. Rotate manually to confirm smooth operation.
- Install Wear Plate: Position the new wear plate (66T-44323-00) over the impeller, aligning all passages and bolt holes.
- Gasket & Cover: Install the new gasket (63D-44316-00) and O-ring (93210-59MG7), then secure the pump cover (63D-44312-00) with the provided bolts (90119-08M15) in a star pattern.
- Replace Thermostat: Remove the old thermostat and install the new one (6E5-12411-30) with its gasket (676-12414-A1). Ensure the temperature-sensing element faces the correct direction.
- Install Anode & Accessories: Replace the sacrificial anode (67C-45251-00) and install the new fuel filter (61N-24560-00) and gear oil pump (24OP149) as applicable.
- Reassemble Lower Unit: Install drain gaskets (90430-08020) at drain plug locations and secure the cotter pin (91490-30025). Reattach the lower unit and torque all fasteners to specification.
- Test & Verify: Reconnect fuel lines, run the engine in a test tank or on muffs, and verify strong water stream from the tell-tale indicator. Check for leaks and proper operating temperature.
Troubleshooting & FAQ
Q: How do I confirm this kit fits my Yamaha outboard?
A: Verify your engine model number matches 40XWT or E40XMH and falls within the 1998-2019 year range. Cross-reference the OEM part number 676-W006A-00 in your service manual or on the original pump housing to ensure compatibility.
Q: How often should I replace my water pump impeller and kit components?
A: Yamaha recommends replacing the water pump impeller every 2-3 years or 200-300 hours of operation, whichever comes first. If your engine overheats, shows weak water flow from the tell-tale, or has been in storage, immediate replacement is advised.
Q: What are the signs that my water pump is failing?
A: Common symptoms include engine overheating, weak or absent water discharge from the tell-tale indicator, steam from the engine, loss of power, and alarms or warning lights. Inspect the impeller immediately if any of these occur.
Q: Does this kit include everything I need for a complete water pump service?
A: Yes, this comprehensive 16-piece kit includes the impeller, wear plate, gaskets, seals, hardware, thermostat, fuel filter, anode, and gear oil pump—everything required for a thorough cooling system overhaul on compatible Yamaha 40HP 2-stroke models.
Q: Can I install this kit myself or do I need a professional mechanic?
A: If you have mechanical experience and the proper tools, DIY installation is possible following the service manual. However, professional installation is recommended to ensure correct assembly, torque specifications, and reliable performance.
