I have a 12 foot aluminum hull that I use to run jug lines in the bayou near my house. I normally use a 2.5 Mariner water cooled, but the bayou has gotten full of lilies lately and I dont want to run into problems overheating. I was looking on ebay and saw they have some 2.5-4 hp air cooled 2 stroke and 4 stroke outboards, chinese made and pretty cheap, for 200-500 bucks. Does anyone own one or have any experience with one? would I be better off with the 2 stroke or 4 stroke?
