Power tilt and trim system for outboard drive

A hydraulic tilt and trim system for an outboard drive comprising a clamping bracket including a pair of arm members spaced apart from each other, one of the arm members having a through-hole, a swivel bracket supporting the outboard drive, an actuator arranged to operate generally between the clamping bracket and the swivel bracket, the actuator including a variable volume fluid chamber and an extendable rod, a pump selectively supplying a working fluid to the fluid chamber so as to move the rod, and a motor selectively driving the pump, and at least a portion of the motor extending through the through hole.

A hydraulic tilt and trim system for an outboard drive having a propulsion unit, comprising a clamping bracket adapted to be affixed to an associated watercraft, a swivel bracket held by the clamping bracket for pivotal movement about a generally horizontally extending pivot axis and adapted to support the propulsion unit for pivotal movement about a generally vertically extending steering axis, the clamping bracket including a pair of arm members spaced apart from each other, one of the arm members having a through-hole, a cylinder, a piston slidably supported within the cylinder and defining a variable volume fluid chamber, an actuator rod extending from the piston beyond the cylinder, one of the cylinder and the actuator rod being affixed to a shaft that connects the respective arm members for pivotal movement, the other one of the actuator rod and the cylinder being affixed to the swivel bracket for pivotal movement, a powering assembly disposed near to the cylinder so as to selectively supply working fluid to the fluid chamber, and a portion of the powering assembly extending through the through hole of the arm member.

A hydraulic tilt and trim system for an outboard drive comprising a support member that is adapted to couple to the outboard drive, the support member including a pair of bracket arms spaced apart from each other, one of the bracket arms having an opening that opens into a hollow formed on an outer side of the bracket arm, an actuator nested between the bracket arms and arranged to move the outboard drive, and a powering assembly disposed next to the actuator and arranged to power the actuator, at least a portion of the powering assembly lies within the hollow.

An outboard motor comprising an internal combustion engine for powering a marine propulsion device, the engine having a cylinder body that defines a cylinder bore in which a piston reciprocates, a cylinder head closing an end of the cylinder body and defining a combustion chamber with the piston and the cylinder head, an air induction device arranged to supply an air charge to the combustion chamber, the cylinder body having a pair of sides that extend generally along a reciprocation axis of the piston, the air induction device disposed on only one of the sides, a drive unit carrying the marine propulsion device, a hydraulic tilt and trim system supporting the drive unit, the hydraulic tilt and trim system including a support member that couples to the drive unit and has a pair of bracket arms spaced apart from each other, one of the bracket arms having an opening, an actuator nested between the bracket arms and arranged to move the drive unit, and a powering assembly disposed next to the actuator and arranged to power the actuator, at least a portion of the powering assembly extending through the opening, and the bracket arm that has the opening being positioned closer to the side on which the air induction device is disposed than the other side of the engine.
