Friz,
Not sure of the dimensions of your bracket, but your swim platform looks much higher than mine, and the motor mount surface also looks like it's taller than mine so I suspect you could lower the bracket quite a bit from where it is in that last picture, and you'd still be able to raise the motor high enough. The problem with mine is that mount surface isn't high enough to raise the motor any further, and if it was, the lower bolts would want to be right where the swim platform is! On motor height, I have raised my motor one hole or 3/4" above where it is in last picture where it shows the AV plate about 3 1/2" above keel, so it's now at 4 1/4" above keel and the AV plate is still under water, so I think the AV plate wants to be roughly 5" above keel with this bracket with a 30" setback. Sounds like your motor is at least 50 lbs heavier than mine so it might sit a bit lower in the water. (don't forget that the quoted weights are dry weight, so need to add 7.4 lbs/gal for lube oil; don't know it it's true, but I've also heard that some of the quoted 4S motor weights are exactly what you'd read with motor hanging on a scale, i.e., they DON'T include weight of the cowling, so they could be low by another 20 lbs or so!)
Don got the bracket mounting height perfect on mine, with swim platform just an inch or two above the water with a heavy cruising load. Here some pictures and dimensions off mine to give you some ideas. The waterline is right at the top of the green paint, below 3/4" wide gelcoat stripe and 2" wide green bootstripe. When a couple of average size guys (~170 lbs) are on the platform, it's just above the water.
The V at bottom of flotation tub is 4.25" above keel. The swim platform is roughly 16.5" above bottom of tub and about 10" above the chine, as measured along the surface of the transom. For flotation tub comparisons, mine is approximately 32" wide at the tank chines and about 36.5" wide at the top of the tub. Denny
