ABSTRACT:
A jet drive boat propulsion unit cover for purposes of covering the fluid intake of a jet powered boat. The cover accommodates itself to the intake opening including the grillwork thereof, in a manner whereby it covers and seals the intake from foreign objects which might contaminate and adversely affect the wear and operation of the jet power unit, such as the impeller, bearing surface, and other wear areas. The cover is secured by means of an overcenter latching linkage having a member that moves eccentrically around an axis to cause a hook to engage the grating or grillwork of the opening so that it can be easily latched and unlatched. The foregoing provides a generally sealed relationship around the edges of the opening to prevent the migration of foreign matter into the jet drive unit.
