Very Nice looking boat, cant beat a custom aluminum hull for La. I would very much consider more motor. I have a 18.6 Hankos with a 150. It runs 50 fully loaded with 36 gal of gas, 2 men, plus all tackle, gear and other BS. A boat that size may need a 200 or 225. Just some friendly advice.
In any case great looking boat and hope you enjoy yours as much as I enjoy mine.
