An engine mount is slidable up and down the support frame to move an outboard engine carried on the mount in use between a lowered operating position in the water and a raised stored position above the bathing platform. ## Claims ### Claim 1 An outboard engine mounting assembly for mounting an outboard engine on a boat having a bathing platform spaced downwardly from a top of a transom of the boat and projecting rearwardly from the transom, the assembly including: a support frame having a front end and a rear end; attachment means for attachment of said support frame to the boat, an engine mount for receiving and supporting an outboard engine, said engine mount being slidably movable on the support frame between a lowered engine operating position for supporting the engine with its propeller in the water and a raised stored position for supporting the engine out of the water, the attachment means being adapted for mounting the support frame at a desired inclination on the boat extending upwardly and forwardly from the rear end to the front end of the support frame with the rear end of the support frame mounted at a rear edge of the bathing platform and the support frame and engine mount cooperate for supporting the engine forwardly of the rear end of the support frame when the engine mount is in the raised stored position. ### Claim 2 (depends on 1) An outboard engine mounting assembly as claimed in claim 1, wherein a carriage and the support frame are adapted to support the engine between the front end and the rear end of the support frame when the carriage is in the raised position. ### Claim 3 (depends on 1) An outboard engine mounting assembly (1) as claimed in claim 1, wherein engine mount supports the engine in an upright position in both the raised and lowered positions. ### Claim 4 (depends on 1) An outboard engine mounting assembly as claimed in claim 1 wherein the attachment means is adjustable on the support frame. ### Claim 5 (depends on 1) An outboard engine mounting assembly as claimed in claim 1 wherein the attachment means comprises an upper mounting bracket secured at the front end and a lower mounting bracket secured at the rear end of the support frame, at least one of said mounting brackets being adjustable on the support frame to vary the distance between the mounting brackets. ### Claim 6 (depends on 5) An outboard engine mounting assembly as claimed in claim 5 wherein the mounting brackets are pivotally attached to the support frame. ### Claim 7 (depends on 5) An outboard engine mounting assembly as claimed in claim 5 wherein the upper mounting bracket has a pair of arms which extend outwardly from the support frame for bridging across a guardrail on the transom of the boat. ### Claim 8 (depends on 1) An outboard engine mounting assembly as claimed in claim 1 wherein the engine mount has a carriage which slidably engages a complementary pair of slide rails on the support frame. ### Claim 9 (depends on 8) An outboard engine mounting assembly as claimed in claim 8, wherein the carriage has rollers which engage in associated channel slide rails on the support frame to slide the carriage along the support frame. ### Claim 10 (depends on 1) An outboard engine mounting assembly as claimed in claim 1, wherein a pair of spaced-apart in-turned channels are provided on the support frame for reception of laterally projecting rollers rotatably mounted at each side of the carriage. ### Claim 11 (depends on 1) An outboard engine mounting assembly as claimed in claim 1, wherein the support frame and the attachment means cooperate to allow adjustment of the inclination of the support frame between 20° and 60° to the horizontal. ### Claim 12 (depends on 1) An outboard engine mounting assembly as claimed in claim 1 wherein locking means is provided for releasably locking a carriage on the support frame. ### Claim 13 (depends on 1) An outboard engine mounting assembly as claimed in claim 1 wherein the engine mount includes an engine mounting block, said engine mounting block being pivotally mounted on a carriage and means is provided for releasably locking the mounting block on the carriage and for adjusting the orientation of the mounting block relative to the carriage. ### Claim 14 (depends on 13) An outboard engine mounting assembly as claimed in claim 13 wherein the carriage has an engine mounting block pivotally mounted thereon for pivoting about a horizontal pivot between the engine mounting block and the carriage and an adjuster link arm extends between the engine mounting block and the carriage, one or both ends of said link arm being adjustably engaged with the carriage and/or the engine mounting block for adjustment of the angle of the engine mounting block relative to the carriage. ### Claim 15 (depends on 14) An outboard engine mounting assembly as claimed in claim 14 wherein an outer end of the link arm is vertically adjustable on the engine mounting block. ### Claim 16 (depends on 15) An outboard engine mounting assembly as claimed in claim 15, wherein the outer end of the link arm is engaged with a rearwardly projecting web on the engine mounting block, said web having a number of vertically spaced through holes, a bolt connecting between the outer end of the link arm and a selected one of said through holes in the web. ### Claim 17 (depends on 14) An outboard engine mounting assembly as claimed in claim 14, wherein an inner end of the link arm is longitudinally adjustable on the carriage for movement towards and away from the engine mounting block. ### Claim 18 (depends on 17) An outboard engine mounting assembly as claimed in claim 17, wherein an elongate bar on the carriage has a number of spaced-apart through holes, a bolt connecting between the inner end of the link arm and a selected one of said through holes in the bar. ### Claim 19 (depends on 1) An outboard engine mounting assembly as claimed in claim 1, wherein a carriage has an inner slide plate in alignment with slide rails of the support frame and an outer engine support portion angled relative to the slide plate and projecting outwardly between the slide rails, the engine mounting block being pivotally mounted at an outer end of the engine support portion. ### Claim 20 (depends on 1) An outboard engine mounting assembly as claimed in claim 1 wherein a winch is mounted on the support frame said winch having a cable wound on a drum, the cable being connected to the engine mount and the winch being operable to raise and lower the engine mount on the support frame.
