DOES ANYONE HAVE INFORMATION OR DRAWINGS ON HOW TO PROPERLY ATTACH AN OUTBOARD MOUNT? THANKS VERY MUCH (ANYTHING YOU HAVE WOULD HELP ME....HOWEVER, I HAVE A MODEL 272 I'M LOOKING TO ADD IT TO)

Specific to the engine and the bracket
there is no one "right" way to mount an outboard bracket. Although most brackets should be mounted with at least four stainless bolts to the transom (with backing plates of some kind), where exactly the bolts go is a function of the bracket's span of motion and the dimensions of the outboard. You need to make sure that the prop will be underwater when the bracket is at its lowest setting, and that you will be able to still reach the controls from the cockpit (unless you are investing in remote controls). If you like to tilt the engine in addition to or rather than moving the bracket up and down, you will have to make sure that the bracket is far enough away from the transom. This will probably require making a spacer block and mounting it between the transom and the bracket. I am unfamiliar with the 272, so I don't know if it was designed to take an outboard bracket. If it wasn't, you should also beef up the transom where you intend to mount the bracket. I would consider epoxying some marine grade plywood to the interior wall of the transom to the spot. Good luck.

Practical thinking
Ralph, I was 'enlisted' to attach one of these onto a sailboat last year. The whole process is on three factors: 1) Strenghth through bolt to a large 'backing plate' I used 3/4" plywood well painted sealed with 5200 as I did not want it leaking. 2) angle of attack, you CAN adjust this on the outboard or use shims or wedges bolted onto the transom. 3) waterproofing, sikaflex, 5200 or silicone, I used 5200 I have had to take apart glued 5200 but it is unlikely if this is aperanent. I am assuming you have one of the 'spring' assisted mounts that will bring that aluminum out of the water? Off to anchor for the firewrks in Richardson's Bay...;-)

BTW
I have mounted these before, but a huge help was looking around my marina to see the others and how they were mounted, talking to people who had done it.

The last time I did this many years ago
I bought a Garelick OB Bracket and it came with some pretty detailed instructions that were not difficult to follow to ensure the OB motor is not too high or not too low. A lot depends on the travel of the bracket up and down, and the length of the shaft on your OB. I recall making a cardboard mock up of the OB bracket footprint that I used to make sure I drilled the four holes in the right place. I then used a yard stick to measure the distance from the top of the OB cavitation plate to the underside of the power head to determine the high/low position for the bracket on the stern. As noted below, make sure to have a hefty backplate for the bracket.
