Outboard question

I boats never did get back to me.

It's official now that '53, 7-1/2hp fleetwin and the '70 model 115 "starflite" are now mine. And I see an ad on market place for another fleetwin identical to it, same year. Though a lil worse for wear than Dad's.I hate ads that say "make offer" without any sort of number by seller as a guide or idea of what range they're at least hoping for... I've been having a complete power head for "my" original fleetwin on my egag watch list for a while now. But depends on what becomes of this one on market place in the next town I may put the parts that theirs is missing (mainly side covers, more decorative t functional) on from mine and just keep mine as "parts for it and dad's. I actually think I have most of 2 of them in the shed in pieces.
I Remember having Dad's fleetwin and mine on the back of the same boat together both running as "twins" and separate. And mine just didn't have nearly the power that dads did so I decided to get rings and gaskets for it and overhaul it. But when I went to reassemble it something "hit" (interference) that didn't originally, and it wouldn't spin all the way around. I had had that thing apart a few times to try and figure out why. I pulled the plugs on dads to make sure I had the piston dome facing the right way and everything, and eventually gave up on it ... But since it became apparent that dads was finally gonna be mine I started looking into it again. Which was why I've been watching that other power head on egag.
