Would new 20 HP Honda outboard be sufficient to adequately power and plane a 1977 Starcraft 16' long, 5' 6" wide, 550 lb (empty hull only without engine, people and gear)? Most of the time there would be less than 400 lbs of people and gear in boat, so total weight would be around 1,000 lbs. But what if total weight (weight of bare hull plus motor plus people/gear) with more people say, were 1,200 or 1.300 lbs?
