Shaft Couplers by Buck Algonquin and Poly Flex

Buck Algonquin and Poly Flex Shaft Couplers for Marine Transmissions


Buck Algonquin manufactures a complete line of marine shaft couplers to match up to most  makes of marine transmissions.  They are precision machined to SAEJ755 specifications and made in both solid and split styles.  Custom machining is also available for couplers that are not normally produced.  All of Buck Algonquin couplers come with all mounting hardware.  If you have a question or can't find what you are looking for, please contact us for assistance 425-353-0436 or email us here.
Poly Flex produces a high quality parallel clamp steel half coupling that can be split further apart than a traditional split coupling to make installing onto the shaft even easier than a split coupling. All Poly Flex half couplings are CNC machined and plated in an SA5 Cobalt Zinc for up to 6 times more corrosion resistance than traditional zinc plating. We currently have a limited selection couplings online, but will be adding more shortly and can always special order.
