This water pump impeller for Tohatsu outboard engines from CEF Marine is a replacement impeller for the engine's cooling water pump. The impeller circulates cooling water through the cooling system and is designed for Tohatsu engines of 9.9, 15, and 18 hp in both 2-stroke and 4-stroke versions.
The impeller has 8 blades, an internal diameter of 13.97 mm, and an external diameter of 40.8 mm. The axial width is 23.4 mm. These dimensions should be compared with the existing impeller and the engine's original spare part number before installation.
The primary OEM reference is 334-65021-0. The number also appears as 334-65021-0M, 334650210M, and 334-65021-0/M. The CEF part number is 500383, while the short CEF code is 383.
Compatible engine models
OEM applications include Tohatsu M9.9D2, M15D2, M18E2, MX18E2, MFS9.9D, MFS15D, and MFS20D. The variant is primarily indicated for 9.9/15/18 hp; for use with a 20 hp model, the original spare part number and full engine/serial number identification must therefore be checked.
