Hey, This is my first time here, and am wondering what would be a good engine size to power an inflatable boat? I would like to possible pull someone behind it. I am probably going to have mabye 3 friends(1 on tub, and 2 in boat). I am also on a budget, between $5-$2000, because I am only 15. If you have any suggestions on what kind/brand of boat i should get that would be great, and if you have any ideas on another boat that would work for me, that would be great. Thank you in advance!
