Johnson Pump 09-812BT-1 Raw Water Pump Impeller Kit

Johnson Pump 09-812BT-1 Raw Water Pump Impeller Kit

Keep your cooling system performing the way it should with the Johnson Pump 09-812BT-1 Impeller Kit. Designed for modern high-performance inboard engines, this premium raw water pump service kit restores proper water circulation and helps protect your engine from overheating during long surf sessions, heavy ballast loads, and extended idle time.

The raw water impeller is one of the most important maintenance components on any marine engine. Over time, the rubber vanes wear down from heat, debris, and constant operation, reducing cooling efficiency and water flow. Replacing the impeller at recommended intervals helps maintain proper engine temperature, protects internal components, and keeps your boat operating reliably all season long.

Manufactured by Johnson Pump, a trusted name in marine cooling systems, the 09-812BT-1 kit is built using durable marine-grade materials designed to withstand demanding conditions. It’s engineered as a direct replacement for compatible Johnson raw water pumps commonly found on Indmar Raptor engine platforms.
