I think this is the part many don't realize. It's not always getting "big air". Running WFO and getting air under the prop for a split second, or even partially getting air, also cause huge torque spikes.

We run into that when racing in calm water. The prop breaks free and grabs again before I can pull back on the throttles. Now, with the DriveGuardian, I don't worry about it. In the big water, you have some time to pull back, but with the DG, we have the confidence that if I miss we are protected.

Does it rob anymore h.p. in comparison to a rubber coupler????
Does it have a max h.p. rating? ???

Pretty cool idea. Sounds like it's doing a good job so far!
Congrats!

Yes, it robs the transmission and drive of horsepower during spikes that exceed the DriveGuardian rating :D Otherwise there is no loss.
They are on the Qatar boat so I think a horsepower rating may not be an issue for you but I could be wrong :drool1:

true. I've got outboards so I think I'd be shat out of luck. It looked a bit bulky, I was wondering if it has more rotating mass, than a coupler, and exactly how it works? Like a cush drive on a motorcycle? Either way pretty interesting product for sure

MDC has designed and fabricated components that are being used by Spirit of Qatar but the team is not running DriveGuardians at this time. The Bravo version is nearly the exact same physical size as the stock coupler but does weigh a little more. Even so, the Moment of Inertia is relatively low since the mass is close to the center of rotation, which is the opposite of a flywheel. The NXT and SSM version have a lower Moment of Inertial than the stock setup. There is no added friction and no loss of HP.

My bad, thanx for the correction Mike.

If there is a loss it's extremely small. We didn't lose any MPH. Not at all.
