ABSTRACT:
A stern drive handling device includes a wheeled lower support frame and an extensible upper support frame telescopically mounted on the lower support frame. A horizontally disposed hollow sleeve is secured to the upper end of the upper support frame and a screw jack is provided for adjusting the height of the sleeve relative to the lower support frame. A support bracket assembly is pivotally mounted in the sleeve for swinging movement about a horizontal axis and a pair of pivoted clamps adapted to engage the cavitation plates on the housing of a stern drive unit are pivotally mounted on the support bracket assembly for pivotal adjusting movement about a second horizontal axis orthogonal to the first horizontal axis. The clamps may be secured in any desired pivoted position and limit stops are provided to limit the pivoting movement of the clamps.
