thanks again...

My point was that I think the 1"/foot of setback "rule" is bogus, at least for a Hermco bracket on a 20' SeaCraft Seafari! In my case the AV plate needs to be somewhere around 4.5-5" above keel for a 30" setback. My old motor mounted on transom had the AV plate about 1" above keel. So I needed to raise motor about 3.5-4" higher when moving motor aft by 2.5'. Therefore the "rule" in my case would raise motor 3.5" to 4"/2.5' = 1.4 to 1.6"/foot of setback!
Before anyone casts this "rule" in concrete, let me double check my AV plate height, as I haven't actually laid a ruler on it since Don raised my motor approximately 1"! Will try to get a measurement/picture in the morning!
