How to Install a Water Pump on an Evinrude Outboard

Marine engines need to cool themselves internally to ensure consistent performance. The Evinrude Outboard does this by pumping water into the exhaust manifold. Over time, parts of the water pump fall victim to wear and tear, which reduces the effectiveness of the pump. Without a fully functioning water pump, the engine can overheat, leading to further damage.

Instructions

1

Open the Evinrude Outboards lower unit to gain access to the water pump. This is located at the top of the unit.

2

Place a drive shaft seal into the opening on top of the water pump housing, using a socket wrench to push the seal firmly into place. Cover the seal lightly in grease.

3

Put a new water tube grommet in the top of the pump housing.

4

Put gasket sealing compound on the replacement gasket for the impeller plate. The gasket fits onto the lower unit cover. The impeller plate fits on top of this.

5

Place the drive pin into the driveshaft. You may find a small amount of grease helps with this process.

6

Paint a thin coat of grease on the opening to the impeller housing and slide the impeller down onto the drive shaft. When done correctly, the groove in the impeller will slide over the drive pin.

7

Slip the pump housing over the impeller and twist the driveshaft by hand in a clockwise motion.

8

Place the water pump over the lower units studs. Add lock washer and nuts, tightening with a torque wrench to 75 inch-pounds.
