Propeller Shaft Cotter Pin PARSUN GB/T91-3.2X18

Compatibility Information

The PARSUN propeller shaft cotter pin GB/T91-3.2X18 is a critical fastening component that ensures the safety and reliability of your outboard motor. Although this product is an original part from the renowned manufacturer PARSUN, its universal manufacturing standard allows it to be used in many drive configurations. Due to the lack of a detailed compatibility list in the technical data, it is crucial to verify fitment based on the catalog number GB/T91-3.2X18 or the original OE number provided in your equipment's manual. Regardless of the engine brand, selecting the correct cotter pin prevents the propeller from loosening, which is critical for maintaining full power and control over your boat. If you have any doubts about compatibility with a specific engine model, we strongly recommend contacting our customer service department, who will help you verify the correct part selection.

Installation and Operation

Replacing the cotter pin is a simple task, but it requires caution. Before disassembly, ensure the engine is turned off and safe. The new cotter pin must be perfectly matched to the drive shaft to prevent vibrations and premature bearing wear. Regular inspection of the cotter pin during technical inspections will help you avoid unexpected breakdowns during your cruise.
