Abstract
A mounting assembly for a marine propulsion system includes a horizontal mounting plate, a pivot housing, and an adapter plate attached to one another through a plurality of vibration absorbing isolation points. The adapter plate is configured for attachment to an outboard powerhead, and the horizontal mounting plate is configured for horizontal attachment to a boat platform. The pivot housing is configured for attachment to a steering arm that extends through the horizontal mounting plate for rotating and pivoting an attached steering arm yoke and trunnion assembly and propeller drive unit. A contoured opening in the horizontal mounting plate facilitates drop down installation of a marine propulsion system.
Claims28
A method for mounting a marine propulsion system to watercraft platform including a recess therethrough, the marine propulsion system including a horizontal mounting plate, a powerhead, a steering arm yoke and trunnion assembly, and a propeller drive unit, said method comprising the steps of:
- extending at least a portion of the steering arm yoke and trunnion assembly through the horizontal mounting plate;
- mounting the powerhead to the horizontal mounting plate, such that at least a portion of the steering arm yoke and trunnion assembly is maintained in position relative to the horizontal mounting plate;
- positioning the horizontal plate into the boat platform recess;
- wherein the horizontal mounting plate includes a plurality of isolation points, the propulsion system further includes a pivot housing having a plurality of isolation points and an adapter plate having a plurality of isolation points, the adapter plate connected to the powerhead, the method further comprising the steps of:
- aligning the pivot housing isolation points with the horizontal mounting plate isolation points;
- aligning the adapter plate isolation points with the pivot housing isolation points;
- and
- attaching the pivot housing, adapter plate, and horizontal mounting plate with a fastener extending through the isolation points.
A mounting assembly for a marine propulsion system including a powerhead, said mounting assembly comprising:
- a horizontal mounting plate;
- a pivot housing attached to said horizontal mounting plate;
- an adapter plate attached to said pivot housing and adapted for attachment to the powerhead;
- and
- wherein said horizontal mounting plate comprises at least one isolation point and an opening therethrough, said pivot housing comprises at least one isolation point and an opening therethrough, and said adapter plate comprises at least one isolation point and an opening therethrough, said at least one isolation point of said horizontal mounting plate aligned with said at least one isolation point of said pivot housing, said at least one isolation point of said pivot housing aligned with said at least one isolation point of said adapter plate, and at least one attachment member extending through said openings to secure said horizontal mounting plate, said pivot housing, and said adapter plate to one another.
A mounting assembly for a marine propulsion system including a powerhead, said mounting assembly comprising:
- a horizontal mounting plate;
- a pivot housing attached to said horizontal mounting plate;
- an adapter plate attached to said pivot housing and adapted for attachment to the powerhead wherein said pivot housing comprises a central drum having a central opening therethrough and a raised slot surrounding said opening, and a plurality of mounting brackets extending therefrom;
- and
- a steering arm, wherein said pivot housing further comprises a raised surface forming a groove for receiving the steering arm.
A mounting assembly for a marine propulsion system including a powerhead, said mounting assembly comprising:
- a horizontal mounting plate;
- a pivot housing attached to said horizontal mounting plate;
- and
- an adapter plate attached to said pivot housing and adapted for attachment to the powerhead, wherein said adapter plate comprises:
- a powerhead mount portion and a central opening therethrough;
- an exhaust portion;
- and
- a side plate and a cooling water inlet therethrough.
