Water Pump Shaft Assembly for Rotax Max Evo Kart Engines. This kit is the entire assembly for the impeller that drives water throughout the cooling jackets of your Rotax Max FR125.

All items noted 13-16 are included in this kit. This includes:

• Water Pump Shaft (14)
• Water Pump Shaft Impeller (15)
• Dowell Rod to connect Impeller to shaft (16)

Note that these items are made of plastic, and can over time become brittle and weak, even leading to failure over cold winters! Make sure to drain water from your radiator when not running your kart to keep this system working well.
