Abstract: Disclosed herein is a marine propulsion device comprising a propulsion unit adapted to carry a propeller, a swivel bracket pivotally connected to the propulsion unit for relative steering movement therebetween about a steering axis, a link pivotally connected at one end to the swivel bracket about an axis transverse to the steering axis and having a laterally outwardly extending out-turned end, and a transom bracket adapted to be mounted on a transom of a boat, being pivotally connected to the swivel bracket for tilting movement about a tile axis transverse to the steering axis and parallel to the first mentioned transverse axis, and including a surface extending generally in the direction of intended boat travel and having therein a recess receiving and engaging the out-turned end of the link and biasing the link inwardly, which recess includes an endless main portion, a running position branch portion extending downwardly from the endless main portion, and a shallow water drive position branch portion exten

Abstract: A marine propulsion device comprising a mounting assembly adapted to be mounted on the transom of a boat, and a propulsion unit mounted on the mounting assembly for pivotal movement relative thereto about a generally vertical steering axis, the propulsion unit including a rotatably mounted propeller, and an internal combustion engine drivingly connected to the propeller, the engine comprising an engine block, a timing member mounted on the engine block for movement relative thereto in opposite advance and retarding the spark timing of the engine, a releasable lock for preventing movement of the timing member in the retard direction, and an operator actuatable mechanism for releasing the lock and moving the timing member in the retard direction, and for moving the timing member in the advance direction.
