Vibration-Reducing Flexible Couplers
What is a DRIVESAVER®, exactly?
Good question because you’d be hard-pressed to find the answer online! The definition of a coupler is a “rod or link transmitting force and motion between a rotating part and a rotating or oscillating part” (Random House Dictionary, Unabridged, ©2015). At its simplest, a DRIVESAVER® is a flexible coupler that reduces the vibration of the propeller shaft but also acts as a circuit breaker if the boat propeller hits a log or rock.
Why should I have one for my boat?
It’s better to be safe than sorry. What the DRIVESAVER® does, besides reducing tangible vibrations associated from misalignment between the transmission and propeller shaft, is protect your transmission from costly damage in the event of an accident. I know, I know, you’re the safest driver in the world, right? Which means you always wear your seatbelt and never walk under ladders. But, someone or something still could hit you while driving through no fault of your own. Think of the DRIVESAVER® like a seatbelt for your transmission and propeller shaft — it reduces major headaches if either breaks. Not to mention with the noise and vibration reduction to boot, it will make conversation on your boat that much more enjoyable.
