The 16's are very nice too, and can run with a wise variety of engine but they to have a flared bow... If a 16' starts star gazing at high speed, it won't come down in any manner that your request.. I had a ported 2.5 Merc on a 360 lbs. 16'er and it was blast.. Very fun boat that revved and accelerated like a RC car, but I look back on it and that was a potentially dangerous combo.. Be it wind, unseen wave, trim, etc there was no room for an uninvited flighty bow once the throttle was opened..
I'd like to have a 14 with a 3 or 4 cyl too, gotta be a fun and very fuel efficient ride... The difference in those older smaller boats to what is popular now, is the driver really felt like he was wearing those old boats.. Mine had cable/pulley steering and it was a very one-on-one intimate contact with the boat.. If the boat needed a slight change in posture like a little side wind, you could compensate by leaning more weight on one side or another of your butt to level it out and still keep the gearcase and boat straight with one another... Like riding a strong 250cc 2-stroke dirtbike in terms of connectivity to the rig, just faster than the bike..
