SIERRA 118-3207 Cooling Water Pump Impeller

Compatible Engines

Ensuring the reliable operation of your outboard motor requires the use of original or high-quality replacements, such as the SIERRA 118-3207 cooling water pump impeller. This is a critical component of the cooling system, responsible for the continuous circulation of cooling water and preventing the power unit from overheating. This part is dedicated to engines with a power output of 30 to 70 HP, including DT55 and DT65 models (manufactured between 1985 and 1995). Due to the specifics of spare parts selection, compatibility must be verified by the manufacturer's catalog number 118-3207 or the original OE number. If you have any doubts about fitting a specific model, we strongly advise contacting our customer support to select the perfect part.

Installation and Operation

Replacing the impeller is a standard maintenance service that can be performed yourself. It is important to check the condition of the seals and the pump chamber before installation. The new impeller should be carefully lubricated with seawater or special grease to prevent it from drying out and getting damaged during the first start-up. Regular replacement of this element prevents failures and extends the life of the engine.
