Did you miss the looks crappy and unnecessary part of my response? It's not a bad thing, just looks weird. Unless your boat is like new it'll make your boat look worse too. If you have a nice vintage tinny, why not restore a vintage motor to go with it? I'm still looking for an older OMC motor for my Mirro, even though I have 2 motors for it already. I'd just love to have a 60s Jonnyrude 25-35 to complete the look. I'd think some of you older guys would follow what I'm saying. Keep your classic 100% classic!
Maybe it just comes down to taste, but I find new motors on old boats pretty unappealing. It just looks wrong.
