I'm not new to boats, but am just a novice when it comes to engine troubles. I bought a little 15 hp mercury (1996) 2 stroke and here's what happened. It will start and idle like its brand new, but when I put it in gear and give it gas it dies pretty quick. I had a friend check it out and he found a little clog. I would like to work on it myself but am afraid I'll screw it up.. With a manual in hand, can a novice like myself be safe working on it or should I take it to a pro? Thanks for any replies.
