ABSTRACT:
A support device maintains an outboard unit of a boat engine in a tilted position for travel. The outboard unit has a stationary drive shaft housing attached to the boat transom and a movable propeller drive unit pivotally attached with respect to the stationary drive shaft housing. A trim mechanism includes a cylinder, a hydraulically operated piston and an actuator rod engaged between the movable propeller drive unit and the stationary drive shaft housing for tilting the movable propeller drive unit to a desired angle between a lowered position and a raised position. The support device has an elongated rigid casing with a radial slot extending along the entire longitudinal length of the casing and a semi-rigid lining disposed within the casing forming a longitudinal aperture comunicating with the radial slot through the casing. With the trim mechanism in the raised position and the actuator rod extended, the casing is engageable over the actuator rod for supporting the movable propeller drive unit in the raised position for travel, wherein the rigid casing engages against the cylinder at one end and against a pivot support connection of the actuator rod to the propeller drive unit at another end. The semi-rigid lining substantially covers the actuator rod for protecting the actuator rod against nicks and abrasions due to flying gravel and the like.
