Transom Bracket Mounting Height

[ApolloHT]

Strick...

36" setback is not committed as of yet, I could always modify my design to be 30"...the setback distance is an open issue for me, although the Suzuki needs at least 24" to clear at full tilt. Of course I want to buy myself a little more room, so maybe 36" is a little overboard...but then, how is the setback distance measured? Is it measured from the motor mount, in a straight line, to the transom, or is it measured from the motor mount, to the bottom of the transom? I want to be comparing apples to apples, and maybe the dimension I am referencing from my design, is not the correct dimension.

In any case, if I gave you a 30" engine bracket, to mount on the back of your transom, and the 30" was measured per the correct way (as I asked about above), and you had a 30" shaft O/B, what distance from the plane of the keel, would you mount it? Knowing that you would be safe, and any future adjustment would require raising the O/B...not having to worry about lowering it?

Note: I have the manual (PDF file) of setting up the Suzuki DF250, and in this manual they provide a detailed drawing of all the dimensions of the O/B...so I don't really need the motor's anticavitation plate as a measuring stick, I hav it all laid out on CAD, per the drawing. So I know my dimensions are on the money...just don't know where to set my motor mount height for the desired setback, to get the floatation part of the bracket designed. I also plan to use my existing 24" trim tabs, so this will limit the width of the floatation part of the bracket slightly.
