I was looking at an older 184SC model Champ that has had a new 200HP Yamaha engine installed on it. My dads 184DC is only rated on the tag for a 175 which his boat has. I'm looking for my own boat now and this one seems like a good deal. However, what is the downside to a 200 being on a boat only rated for 175? Will my insurance not carry it? Is the boat built strong enough for it? Kind of an odd question but any help would be appreciated from the experts! Matt
