DriveGuardian contains a clutch pack with a Kevlar friction material similar to some high-performance automotive racing clutches. The clutch pack slips a fraction of a rotation each time the propeller re-enters the water so the service life will likely exceed most engine rebuild cycles. However, the clutch plates are replaceable when the need arises.

Another question. Since it is torque based slip, is there a power limit that the unit has before being overcome by the engines torque? For example getting on plane with 700ftlbs it wont slip, but what if someone was hard on it with say 1000ftlbs, would it cause clutch slippage getting on plane or accelerating hard.

Great question Philm, each DriveGuardian is calibrated to transmit a torque value that is greater than the engine's peak output. So, it will not be possible to make the clutch slip by simply accelerating too hard.

Each DriveGuardian is calibrated for a specific maximum torque that is usually at a preset value that is just above the peak output of the engine. So, yes an engine upgrade would most likely require a recalibration.

So during a repower or engine upgrade these would have to be sent back to the factory for recalibration then?
Sorry for all the questions, just find this to be pretty interesting.

So my interest has been peaked! Very cool product!
I noticed they have a model for an SSM. Would this unit basically work on any outdrive that uses a transmission? Is it still as effective? With a transmission in between the outdrive and the engine which is also full of clutch plates does a transmission increase or decrease its effectivity?
I am in the process of converting my 84 scarab from BW and TRS to MG502 and Kaama surface drives. Would there be a benefit in this configuration?
Thanks

502, one of the reasons Mike developed the product is because he was personally blowing up drives and transmissions. The DriveGuardian replaced the coupler and it protects not only the drive but the transmission also.
The original design was developed for the NXT set up and bellhousing.
In my case we could not fit the DriveGuardian in that small space without going to new starters and different flywheel but now Mike has also solved that issue.

Mike correct me if I`m wrong but with the latest design it is much more compact and fitment should not be an issue.
I also have a tech brief for anyone interested ...
