Specs At A Glance

Good To Know

Q: How is fitment verified for this impeller? A: Fitment is verified by matching the existing impeller part number to 3B2-65021-1 or 500344 and confirming the outboard is 6HP, 8HP, or 9.8HP.

Q: What does the key in this kit do? A: The key drives the impeller on the water pump shaft so the impeller rotates and moves cooling water.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
