Are they simply to get the engine higher? If so, why not just mount
it higher?
I was of the impression that a jack plate lets you mount the engine higher
without having to redo the transom. In other words, you can't mount the
engine higher if there is no transom there to bolt it to and thus the need
for the jack plate. Some jack plates, I've seen also give you the ability
to lift the engine up to navigate shallow water. Would work better than
tilting the engine.
