Thanks for the response Brian!
I can offer $350 shipped for my "nostalgia" build but for much more, I become more inclined to just install the CMB already waiting on me.
I understand the values you put on this engine and don't disagree for the exact right person, it's just that our values aren't 100% aligned.
For example, I would pay $425 and maybe more for less of an engine NIB Super Tigre G65 for this particular boat so I could build exactly as it as was originally intended in the late 70's when my dad started it...using exh. throttle & water cooled head we made and good ole side exhaust stack. Kid me in the 80's put it in a Sk daddle 40 with an OS carb and wore it out. This Rossi a better fit than the CMB in this WingDing for me....I'd say it fits my plan about 82% as well as a good/NIB G65 would.
