This part is designed for older Johnson/Evinrude outboard models, including engines with power ratings from 3 to 7.5 HP manufactured in the 1950s and 1960s. Due to the specifics of older power units, compatibility must always be verified by the manufacturer's catalog number or OE number to avoid selection errors. If you have any doubts about fitting this part to a specific year or model, we strongly recommend contacting our customer support to verify the part.

Installation and Maintenance

• Original SIERRA quality – guarantees durability and precision manufacturing.
• Perfect fit – dimensions of 69x12.8x11 mm ensure a tight water circulation seal.
• Easy replacement – simple design facilitates servicing in home conditions.
• Overheat protection – a key element for safety on the water.

Replacing the impeller is one of the most important maintenance tasks. We recommend tightening screws moderately to avoid damaging the threads in the pump housing. Regular inspection of the impeller condition prevents failures during the cruise.
