What Is Included
This listing is for the water pump service components supplied as a repair kit without the water pump housing. The housing is not included. Because the existing housing must be reused or replaced separately, inspect it for scoring, corrosion, cracking, distortion, or excessive wear before installation.
Installation Notes
- Confirm that your outboard is a Yamaha F115 4-stroke from the specified 2002–2023 range and compare the existing water-pump arrangement with the replacement kit.
- Disconnect the battery and follow the safety procedures in the engine service manual.
- Remove the lower unit according to the manufacturer’s service instructions.
- Remove the water-pump cover and take out the worn impeller and service components, noting their orientation.
- Inspect the existing housing carefully. Do not reuse a housing that is damaged or excessively worn; this product does not include a replacement housing.
- Clean all mating surfaces and remove old gasket material and debris.
- Install the replacement service components in the correct order and orientation. Ensure the impeller vanes are positioned according to the direction of engine rotation.
- Reinstall the water-pump cover and lower unit, tightening fasteners to the torque specifications in the Yamaha service manual.
- Run the engine in an appropriate water supply after assembly and verify a steady tell-tale stream and normal operating temperature before returning the boat to service.
Troubleshooting & FAQ
How do I confirm that this kit fits my engine?
Confirm that your engine is a Yamaha F115 4-stroke manufactured from 2002 through 2023 and compare the required OEM reference with 68V-W0078-00. Check the complete model designation and consult the service manual if your engine has been modified or has a non-standard water-pump assembly.
Does this kit include the water pump housing?
No. This is the version supplied without the water pump housing. Inspect your original housing before installation and replace it separately if it is worn or damaged.
What are common signs of a worn water-pump impeller?
Common signs include a weak or missing tell-tale stream, overheating warnings, or reduced cooling-water flow. Stop the engine and investigate promptly if overheating occurs.
Should the housing be replaced during every water-pump service?
Not necessarily. A reusable housing may remain in service when it is smooth, undamaged, and within the manufacturer’s specifications. Replace it separately if inspection shows scoring, corrosion, cracking, distortion, or excessive wear.
Is this an OEM Yamaha part?
No. This listing is for an aftermarket replacement repair kit intended to replace the Yamaha OEM reference shown above. Yamaha is the manufacturer of the referenced engine and OEM part number, not the manufacturer of this aftermarket kit.
What maintenance interval should I follow?
Follow the inspection and replacement schedule in your Yamaha owner’s or service manual. More frequent inspection may be appropriate when operating in saltwater, sandy water, silty water, or other demanding conditions.
Shipping speed and cost?
Shipping methods, delivery estimates, and costs are shown at checkout based on destination and availability.
Warranty and returns?
See the current store warranty and returns policy for applicable coverage, eligibility, and return instructions.
