The DriveGuardian

DriveGuardian is a patented device (US 8,771,087) that replaces the Bravo rubber coupler or damper plate with a torque-limiting clutch that absorbs and dissipates the spikes.

DriveGuardian eliminates the source of the damage instead of playing a losing game of trying to make each component strong enough to handle 4X the engine’s torque.

About Marine Design Corp

We are avid offshore power boaters, just like you.  We raised our children going boating every weekend, and even after 24 years we all still enjoy it.

Illinois has a very short boating season, and when we used to break drives, we could easily be out for the rest of the season…not to mention the financial expense of replacing a drive, and lost quality time with our family.
So during those long winter months, Mike started thinking about how to avoid breaking another drive. Since driving it gently and only on the calmest of days was really not an option for us, he invented DriveGuardian.
