I will say this, no factory recommendations seem to get the bracket mounted right on a SeaCraft hull. I would listen to the wise up here vs the manufacture. The manufacture will have you mount the bracket where it will set the motor to low normally. The add an inch of height per inch of set back rule is normally not enough for the hull. When kmoose says 2-5 that would be a good adjustment range for the av plate above the hull bottom. Motor all the way down will give you 2-3 inches and then you will find as you raise it up from there you will get better performance. You don't want to be maxed out on adjustment just to get the AV plate 2-3" above stright edge or hull bottom. If you could run an stright edge off the keel several feet behind the boat and mock the bracket up and measure from the tab top down to the stright edge you will get best results figuring you motor height. Once you figure out how far down the av plate will hang from the bracket mounting tab you can do some math to see how high up the tab needs to be to place you AV plate where you want it. I would start out with the AV plate 2" or 3" above the stright edge with the outboards adjustment all the way down tight to the tab so you could raise the outboard on the bracket tab to go higher if needed. If your AV plate is at least 2" above the keel with the outboard all the way down on the bracket tab you should still be able to move the outboard upwards and have several more inches of adjustment up to find optimal position.
