Disclosed herein is a marine propulsion device comprising a mounting plate adapted to be secured to the bottom of a boat hull in watertight relation and having therein an endless surface defining an opening, and a margin extending from the endless surface, a resilient member comprising an annular sealing portion including an endless surface defining a central opening and a plurality of angularly spaced extensions which project outwardly from the annular sealing portion and constitute elastomeric mounts, a clamping member including an annular portion located within the central opening of the resilient member and defining a central opening, and a flange portion extending outwardly from the annular portion, a lower unit extending through the opening in the clamping member and including a mounting flange, and means securing the clamping member to the mounting flange with the annular sealing portion of the resilient member located between the mounting plate and at least one of the lower unit mounting flange and the clamping member so as thereby to effect a watertight seal between the lower unit and the mounting plate and with the extensions located between the margin of the mounting plate opening and one of the lower unit mounting flange and the clamping member flange so as thereby to support and vibrationally isolate the lower unit from the mounting plate.
A marine propulsion device comprising a mounting plate adapted to be secured to the bottom of a boat hull in watertight relation and having therein an endless surface defining an opening, and a margin extending from said endless surface, a resilient member comprising an annular sealing portion including an endless surface defining a central opening and a plurality of angularly spaced extension which project outwardly from said annular sealing portion and constitute elastomeric mounts, a clamping member including an annular portion located within said central opening of said resilient member and defining a central opening and a flange portion extending outwardly from said annular portion, a marine propulsion lower unit extending through said opening in said clamping member and including a mounting flange, and means securing said clamping member to said mounting flange with said annular sealing portion of said resilient member located between said mounting plate and at least one of said lower unit mounting flange and said clamping member so as thereby to effect a watertight seal between said mounting plate and at least one of said lower unit mounting flange and said clamping member so as thereby to effect a watertight seal between said lower unit and said mounting plate and with said extension located between said margin of said mounting plate opening and one of said lower unit mounting flange and said clamping member flange so as thereby to support and vibrationally isolate said lower unit from said mounting plate.
A boat comprising a hull including therein a bottom having therein an endless surface defining an opening, and a margin extending from said endless surface, a resilient member comprising an annular sealing portion including an endless surface defining a central opening and a plurality of angularly spaced extensions which project outwardly from said annular sealing portion and constitute elastomeric mounts, a clamping member including an annular portion located within said central opening of said resilient member and defining a central opening and a flange portion extending outwardly from said annular portion, a marine propulsion lower unit extending through said opening in said clamping member and including a mounting flange, and means securing said clamping member to said mounting flange with said annular sealing portion of said resilient member located between said boat hull bottom and at least one of said lower unit mounting flange and said clamping member so as thereby to effect a watertight seal between said lower unit and said boat hull and with said extensions located between said margin of said boat hull opening and one of said lower unit mounting flange and said clamping member flange so as thereby to support and vibrationally isolate said lower unit from said boat hull.
A marine propulsion device adapted to be supported in a boat hull and to extend through an opening in the bottom of the boat hull, said device comprising a marine propulsion lower unit extending through the opening in the boat hull and including a mounting flange, a clamping member including an annular portion located within the opening in the boat hull and defining a central opening through which said lower unit extends, said clamping member also including a flange portion extending outwardly from said annular portion, a resilient member including an annular sealing portion having an endless surface defining a central opening located outwardly of said annular portion of said clamping member, said resilient member also including a plurality of angularly spaced extensions which project from said annular sealing portion and constitute elastomeric mounts, and means securing said clamping member to said mounting flange with said annular sealing portion of said resilient member located between said mounting flange of said lower unit and said flange portion of said clamping member.
