Driveshaft housing attachment

An attachment for a driveshaft housing of a boat propulsion unit for protecting swimming creatures in the water from the housing and associated propeller and for protecting the propeller, while improving the efficiency of the propulsion unit, comprising;

• (a) a plate member having an upper end adapted to be positioned forward of a housing and to depend arcuately downwardly and rearwardly to terminate in a trailing lower end, said plate member tapering outwardly along lateral edges from said upper end to said lower end to divert swimmers around and under a housing and propeller, said downward and rearward configuration of said plate member reacting to the passage of water when under way to urge a boat's stern upwardly toward a more efficient operating position,
• (b) means connected to said upper end of said plate member having a configuration for receiving a leading edge of an upper portion of a driveshaft housing to maintain said upper end aligned with the driveshaft housing and to reduce vibration,
• (c) means connected to said lower end of said plate member having a configuration for receiving a skeg at the bottom of a housing to maintain said lower end aligned with the driveshaft housing and to reduce vibration, and
• (d) means for releasably securing said upper end of said plate to a driveshaft housing.
