Default Re: Motor height on bracket

The normal formula for brackets is to raise the motor 1" (relative to a transom mount) for every foot of setback. Don Herman raised mine 2.5" for the 2.5' setback of the Hermco bracket. I was subsequently able to raise it another 2" and still have no problems with ventilation in hard turns unless I have motor trimmed pretty far out. Can run at 50-60% of max uptrim; it starts to porpoise at about 70%.

I'd say keep raising it until you run into ventilation or porpoising problems problems, but keep an eye on water pickup - need to make sure it's still below bottom of hull.
