Abstract
In combination with a water craft (10) having an engine compartment (12), a blower (14) for purging the compartment of noxious vapors, an electrical system (16) for energizing the water craft, a manual blower switch (18), and a speedometer (20) including a tube (22) which provides fluid pressure thereto for sensing the speed of the water craft (10) through ambient water, an improvement comprising a normally closed pressure switch (24) connected to the tube (22). The pressure switch (24) is openable in response to fluid pressure in the tube (22) at speeds above a pre-determined speed of the water craft (10). Electrical connections (26, 28) are provided between the pressure switch (24), the electrical system (16) and the blower (14). The pressure switch (24) bypasses the manual blower switch (18) so that the blower (14) is operated pressure-responsively, irrespective of the manual blower switch (18) when the speed of the water craft (10) is below the predetermined speed, thereby enhancing boating safety.
