Installation Guide
- Disconnect Power: Disconnect the battery and spark plug wires to prevent accidental starting.

- Remove Old Pump: Locate the water pump assembly on top of the lower unit. Unbolt and remove the old pump housing and components.
- Clean Surfaces: Thoroughly clean the mounting surfaces, removing any old gasket material or corrosion.
- Install New Components: Assemble the new kit components in reverse order, starting with the wear plate, gaskets, and pump cup.
- Install Impeller: Slide the new impeller onto the driveshaft, ensuring the key is in place and rotating the shaft clockwise to seat the fins correctly inside the housing.
- Secure Housing: Install the new housing and tighten the bolts to the manufacturer's recommended torque specifications.
- Reassemble & Test: Reattach the lower unit, refill the gearcase oil, and reconnect the battery/spark plugs. Test the engine in water to verify proper water output from the tell-tale port.
Troubleshooting & FAQ
- How do I confirm this fits my engine?
- Start by checking your engine's model, horsepower, and year against the "Compatible Engine Models" table. Be sure to check the notes, as some models have exceptions. Cross-reference the part number with your existing part or service manual. Pay close attention to the exclusion note: this kit does not fit Johnson-rebranded Suzuki engines (2002-2007) or Bombardier 4-strokes.
- What are the signs my impeller needs replacement?
- Common signs include a weak or non-existent water stream from the "tell-tale" outlet, engine overheating alarms, or a noticeable decrease in cooling performance. It is recommended to replace the impeller every 1-2 years or every 100-200 hours of use, regardless of visible wear.

- Yes, this kit is compatible with specific Johnson/Evinrude 9.9 HP and 15 HP 4-stroke outboard models from 1995 to 2001. It is not compatible with later Bombardier-branded 4-strokes.
