229826 Kohler Impeller | Genuine OEM Marine Part

🔧 Product Description

Genuine Kohler Marine Seawater-Pump Impeller Kit - Part Number: 229826

Genuine Kohler flexible seawater-pump impeller kit used on selected Kohler marine generator sets. The neoprene 12-blade impeller draws raw water through the heat exchanger and wet-exhaust cooling circuit.

The impeller measures approximately 62.5mm in diameter and 22mm in width and uses a 16mm keyed hub. Pump configuration must be compared with the removed impeller because selected generator models were produced with more than one seawater-pump arrangement.
