I recently picked up an older Suzuki 2 stroke 4 HP outboard for my raft. Seems to start and run great but haven't tested it on the waters yet. My concern is that a co-worked said in some lake or rivers, a 2 stroke outboard is Prohibited for some reason. Don't want to go to the wrong lake or river and get a citation. Sorry I didn't do my homework before purchasing the outboard, but would like to know facts of this regulation if someone can point me out in the direction. Links to the website reg would be great as well a personal experience as I have never used an gas powered outboard before. Thanks in advance.
