I found a 60hp johnson "loop charged" motor that I was considering putting on my boat. I have right now a 83' 50hp johnson that does fine, but the boat is rated for 60hp so I figure why not. Couple of questions, what is loop charged? Will I notice the 10 hp increase, mine is a 2 cyl., this looper is a 3 cyl.? is the extra weight worth 10 hp?
