I'm LOVIN' that full tranny w/that gentle curve along top...
...Man that is SHAWEET!!...and the sea-drive is best to convert cause tranny is much better cored and has smaller openings...if I was startin' all over again, that's exactly what I'd go with...
One thing I'll pass along (you may already know) is to use a 25" motor rather than 20" as the shorter will swamp when you throttle back coming to a stop...
Anyway, post all the pics ya wanna...we love 'em here and they're real conversation starters...sounds like a great project you are about to start...do you do your own glass work?...
