A good buddy of mine had one on a Key Largo 17. Thing ran like a raped ape with 3 guys, beer and fishing gear. Also pushed us right along with the same 3 guys full dive gear and 6 scuba tanks. He never had a problem with it mechanicaly. Just had a little hard starting in the cold weather. I gave him a call last night he has 1000 hours on it and still going strong.
