Battery Cut-Off Switch with Removable Key - Ultimate Vehicle Theft Deterent!

For my PWC, there is simply nowhere to mount this bulky battery switch. I resorted to simply disconnecting the negative battery post instead of utilizing this item. The item, without the giant red key installed, occupies the volume of a baseball. ideally, you want to mount it to some sturdy part of the transom near the battery. In a PWC, however, space is limited. In order for me to use this, i'd have to do some risky drilling to properly mount the switch-- not worth the hassle.

Waste of $15 for me, but outboard and I/O boat owners will have more space aboard their vessel to properly mount & use this thing, which will be very easy to enable. I have to assume the item aids in avoiding unnecessary battery drain during boat storage.

The product does not come with any explicit directions as to its operation or installation. both should be pretty self-explanatory.
