Abstract:
1. An outboard motor jack plate comprising, in combination: a proximal transom mounting portion having strut holes therein; a distal motor mounting portion having a motor mounting plate; a pair of like-configured L-shaped mounting brackets having an inwardly oriented leg and a rearwardly oriented leg; a top cross support having a pair of parallel downwardly oriented short legs and a horizontally oriented central section; a bottom cross support having a pair of parallel upwardly oriented short legs and a horizontally oriented central section; at least one cross strut; at least one cross strut bushing; at least mounting block bushing; a hydraulic cylinder having a tubular outer casing and at least one hydraulic fitting and a mounting end and a working end; an associated hydraulic pump, a plurality of hydraulic hoses to couple the hydraulic pump to the hydraulic cylinder, at least one fitting and a pump control; the transom mounting portion having a transom plate and a pair of like-configured mounting braces, the transom plate having a generally rectilinear configuration with a flat inward transom facing surface and a flat outward surface with a thickness there between, the transom plate lying in a plane, the transom plate having a plurality of bolt holes there through with each hole having an associated bolt, the bolt passing through the transom plate and through a boat transom for removably coupling the transom plate to the boat transom; the distal motor mounting portion motor plate having a generally rectilinear configuration with a flat outward motor facing surface and a flat inward surface with a thickness there between, the motor mounting plate having a plurality of motor mounting bolt holes there through with each hole having an associated bolt; the like configured L-shaped mounting brackets each having a distal surface oriented toward the inward surface of the motor mounting plate and a rearwardly oriented side surface and an inwardly oriented L-shaped inner surface, each L-shaped mounting bracket having a pair of bolt holes running from the proximal surface of the inwardly oriented leg to the distal surface of the inwardly oriented leg, with each L-shaped mounting bracket having a pair of parallel-ly oriented cross strut holes therein; the top cross support having a generally C-shaped configuration, the central section of the top cross support having an upper surface and a lower surface with a thickness there between, the central section having a pair of mounting block holes there through, each of the short leas having an inward surface and an side surface with a thickness there between, with each of the short legs having a pair of parallel-ly oriented strut holes of the first diameter therein with the strut holes of the short legs being aligned with the strut holes of the L-shaped mounting bracket, the lower surface of the central section having a mounting block coupled there to, the mounting block having a generally rectilinear configuration with a top surface having a pair of threaded bolt holes therein and a bottom surface and a distal surface and a proximal surface and a pair of parallel side surfaces, with the mounting block having a strut hole there through, with a pair of bolts having a thread sized to be received by and mated to the bolt thread of the mounting block, with the bolts coupling the mounting block to the central section of the top cross support; the bottom cross support having a generally C-shaped configuration, the central section of the bottom cross support having an upper surface and a lower surface with a thickness there between, the central section having a pair of mounting block holes there through, each of the short leas having an inward surface and an side surface with a thickness there between, with each of the short legs having a pair of parallel-ly oriented strut holes of the first diameter therein with the strut holes of the short legs being aligned with the strut holes of the L-shaped mounting bracket, the upper surface of the central section having a mounting block coupled there to, the mounting block having a generally rectilinear configuration with a bottom surface having a pair of threaded bolt holes therein and a top surface and a distal surface and a proximal surface and a pair of parallel side surfaces, with the mounting block having a strut hole there through, with a pair of bolts having a thread sized to be received by and mated to the bolt thread of the mounting block, with the bolts coupling the mounting block to the central section of the bottom cross support; the cross strut being fabricated of a rigid material and having a generally solid round shaft configuration with a central axis, each cross strut having the second external diameter with a pair of opposing ends and a length there between, with the first diameter being smaller than the second diameter; the cross strut bushings each having an inner portion and an outer portion with the inner and outer portions having a same central axis and being continuous with each other, the inner portion having a third external diameter and a centrally located passageway of the second diameter; the mounting block bushing each having an external diameter of the third diameter and an internal diameter of the second diameter; and the hydraulic cylinder having a tubular outer casing and a mounting end and a working end having an interior and an exterior and a pair of hydraulic fittings with one fitting being coupled to each end of the outer casing and communicating with the interior, the tubular outer casing having two opposing ends being the closed mounting end and an open ram end, the hydraulic cylinder having a piston located therein with the cylinder having a casing end cap having a ram passageway there through and a ram.
