Abstract
In a marine stern drive (22) having an inboard engine (23), an outdrive (24) with a gimbal bearing (26) at the transom (28) of a boat (30), and a drive coupler shaft (34) extending through the gimbal bearing (26) and between the outdrive (24) and the engine (23), an engine mount installation tool (20) locates the front engine mounts (46 and 48) horizontally on stringers (42 and 44) in the boat prior to installation of the engine (23) to horizontally prealign the front engine mounts (46 and 48) with the front supports (54 and 56) on the engine. The tool (20) includes vertical alignment structure (104, 86, 88) vertically locating the proper height of the front engine mounts (46 and 48) prior to installation of the engine (23) to pre-set the height adjustment of the front of the engine (23) to assure proper alignment of the engine (23) with the gimbal bearing (26) after installation of the engine (23).
