I'm on the market for my first boat  

  but I'm really concerned about how my little 2.0L will handle pulling duty. 
The plan is to get something in the 13-16' range with a trailer so we can keep it at home. 
I know very little about boats so i have no idea how much a boat like that would weigh. I do know a thing or two about Suzukis and i know that my trucklette is only officially suppose to tow 1000lbs. 
So to all you boaters out there; what do ya think? Can my 4 banger handle towing a boat all summer or do i need to invest in a towing rig?
