ABSTRACT:
A hydraulic arrangement for controlling tilt and trim of an outboard drive. The hydraulic arrangement comprises a single cylinder assembly having a single bore inside wherein an upper portion of the bore has a relatively small diameter and a lower portion of the bore has a larger diameter. Two separate pistons, one in each bore portion, are supported for reciprocation. The smaller diameter piston has a piston rod that is directly connected to an element of the outboard drive, while the opposite end of the cylinder assembly housing is connected to an element affixed to an associated watercraft, so as to insure against any undesirable noise or undue wear in the system, and to afford a compact assembly.
