1. An engine deactivation system for use with user operated water vehicles, said system having:

  • at least one waterproof transmitter, each of said at least one transmitter being a portable device transmitting a constant individually identifiable signal powered by an independent power supply, said signal being water sensitive and blocked from said receiver when said transmitter enters the water;

    a waterproof receiver, said receiver receiving and recognizing said individually identifiable signal from each of said at least one transmitter, said receiver having cut-off means, said cut-off means being connected to an engine and having a run mode and a deactivation mode, said deactivation mode shutting down said engine; and

    an antenna, said antenna transmitting said signal between said transmitter and said receiver;

    manual reset means, said manual reset means over riding said receiver cut-off means to manually place said cut-off means in said run mode or said deactivation mode;

    wherein receipt of said signal by said receiver maintains said cut-off means in a run mode and interruption of said constant signal from one of said at least one transmitter immediately activates said deactivation mode, thereby requiring reactivation of said vehicle by reinstating transmission of said signal to place said cut-off means in said run mode or over riding said cut-off means with said manual reset means.
