Hi, I just purchase a new smokercraft tracer and I'm getting ready to mount my 48 special on the back and I have a few questions. I have look at a few motor installation and there seems to be a little vairiance as to up and down placement. Some motors are mounted high off the top of the transom by an inch or so, while other are flat on the top of the transom. Is there a reason for this? why would you not rest the bottom of the transom clamp on the top of the transom before drilling holes? Am I being silly? Any input would be grealtly appreciated....Robert
