Installation Notes
- Disconnect the battery and ensure the engine is securely mounted on a stand.
- Place a drain pan under the lower unit and remove the gearcase oil drain screw to empty the oil.
- Remove the bolts securing the lower unit (gearcase) to the engine's upper section. Carefully separate the lower unit.
- Locate the water pump housing, typically situated on top of the gearcase. Remove the housing bolts and lift the housing off.
- The fixed plates are located within this assembly. Note their orientation, then remove the old plates.
- Clean the housing and surrounding surfaces of any debris or old gasket material.
- Install the new fixed plates, ensuring they are seated correctly according to the service manual diagram.
- Reassemble the water pump housing, impeller, and cover. Torque bolts to manufacturer specifications.
- Reinstall the lower unit, ensuring the driveshaft, shift shaft, and water tube align correctly.
- Refill the gearcase with the recommended marine gear lubricant.
- Once assembled, briefly run the engine in water using a flush attachment ("muffs") to verify proper water pump operation (confirm a steady stream from the tell-tale outlet).
Troubleshooting & FAQ
How do I know if this fixed plate fits my engine?
The best way to confirm fitment is to match your engine's model and year against our compatibility table. Additionally, always compare your existing part's OEM number (e.g., 63V-44328-01) with the numbers listed in our Part Number Matrix.
What are signs of a failing water pump fixed plate?
A worn or corroded fixed plate can contribute to poor water pump performance. Signs include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alarms, or visible scoring and wear marks on the plate during an inspection.
Is this part sold individually or as a pair?
This product is sold as a set of two plates. The Yamaha and Parsun engine diagrams specify that two plates are used together in the water pump assembly, so we provide them as a complete set for one service.
How often should the water pump assembly be serviced?
As a general guideline, the entire water pump assembly, including the impeller and plates, should be inspected annually and replaced every 2-3 years or 200-300 hours, whichever comes first. Service intervals may be shorter for engines operated in saltwater or sandy/silty conditions.
Can I replace just the fixed plate instead of the whole water pump kit?
While you can replace individual components, it is best practice to service the entire water pump assembly (impeller, housing, gaskets, and plates) at the same time. These parts wear together, and replacing only one component may not fully restore cooling efficiency.
Is this an OEM part or an aftermarket equivalent?
This is a high-quality aftermarket replacement part, not an OEM component. It has been manufactured in an ISO 9002 certified facility to meet or exceed original equipment specifications, using comparable materials and undergoing batch inspections for quality assurance.
What are the shipping speed and cost?
We offer fast worldwide shipping, with typical transit times of 5–15 days to most destinations. Standard shipping is free for all orders. If available for your location, expedited shipping options and their costs will be presented at checkout.
What is the warranty and return policy?
This part is covered by a 1-year warranty against manufacturing defects under normal operating conditions. Should you encounter an issue, please contact our support team with your order information. Returns are accepted within our standard return window for items that are unused and in their original packaging. Please see our full policy page or contact us for instructions.
