We like those little Hondas -- they have a distinct (somewhat loud) lawnmower sort-of noise and we can hear them coming way across the anchorage.
I wouldn't worry too much about the lack of neutral. Yes, it would be nice to have FNR, but transmissions add weight and centrifigul clutches can be finnicky. I crewed a fair bit aboard a boat with an old British Seagull that not only lacked any transmission, it didn't even have an "Off" switch. You eventually became adept at guessing when to close the
fuel line so it could run the carb empty and shut down, hopefully just as the bow of the
dinghy nudged alongside the mothership or dock.
Out in the garage we are rebuilding an old Tanaka 2-stroke that can't weigh more than about 12 lbs. I should get some photos...
