very happy with my boat but if you got the dough. get the o/b 4 stroke.
I/O shouldnt load up. You might want to check your carb. AN I/O motor should run just like a car engine (between 600-800 rpm on idle) and will go all day without problems. As far as elevation, you need to go down one main jet size for every 2000 feet of elevation you go up (depends on the exact carb). Be it an I/O or an Outboard, if it has a carb, your gonna have to tune it when you play in the mountains.
Go Fuel Injection on whatever you buy.
