First Claim
1. A fresh water flushing adaptor for outboard and stern-driven marine engines having an external lower propulsion housing which includes a bottom forwardly pointed portion on the lower propulsion housing which further includes water intake parts only along the bottom forwardly pointed portion of the lower housing, said flushing adaptor comprising:
- a molded cover adapted to substantially mateably encase the forwardly pointed portion of the lower housing including the water intake ports on the bottom thereof such that said cover is releasably retainable over the forwardly portion of the lower housing;
fitting means connected to the bottom forwardly portion of said cover for releasable attachment to a supply of water;

Abstract
A releasably retainable fresh water flushing adaptor and method of manufacture thereof for outboard and stern-drive marine engines having an external lower propulsion housing which includes at least one fresh water intake port along the bottom forwardly bulbous portion of the lower housing. The flushing adaptor includes a molded cover which is mateably, releasably self-retaining over this forwardly portion of the lower housing and also includes a fitting connected or connectable into the bottom forwardly portion of the cover for releasable attachment to a supply of fresh water. The fitting has an internal passage in alignment and in fluid communication with the housing water intake. A water distribution groove formed into the interior surface of the cover adjacent the fitting for an increased water flow into the water intake is also provided. Releasable strap means either connected to or completely circumscribing lower housing and cover may also be provided to eliminate any tendency for the cover to be forced from disengagement with the lower housing by engine vibration or water pressure.
