APPLICANT: AB VOLVO PENTA TITLE: BOAT PROPELLER DRIVE UNIT ABSTRACT OF THE DISCLOSURE In an outboard drive unit for boats, the drive shaft housing is swingable by means of hydraulic cylinders for trimming and tilting. One end of each cylinder is pivotally journalled in the shield of the drive unit, whereas the opposite cylinder ends bear against abutment surfaces on the carrier fork shanks conventionally supporting the drive shaft housing. An intermediate member, pivotally connected to the cylinders via pivot pins, is pivotally suspended in the carrier fork, moving along with it during trimming and tilting. A pivot pin fixed into the intermediate member constitutes one part of a mechanical latch means, the other part being formed of a latch hook (not shown) rotatably journalled on the carrier forks. The latch means is thereby completely disengaged upon propeller thrusts during forward travel.
