Midsection height

[TNT Teen]

I'm designing a mod style motor for a lake hydro. Going to use a merc 4cylinder and I'm looking for suggestions on the best height to make the mid.
Thanks for any help.

For lake use I'd stay with the regular "15" inch transom. Safer if you stop intentionally or unintentionally and easier to start without extra help.

I would make a suggestion, except I can't improve on what Sam has said.
