First off I probably should apologize as these outboard motor repair articles started out for someone with some basic knowledge of how motors operate.  It has become apparent because of increased correspondence that an increasingly number who use my articles have almost no knowledge of even the principles of mechanical operation of these devises.  Therefore I am in the process of re-writing or adding other articles directed toward what many of us shade-tree mechanics take for granted.  These articles are not meant to replace factory service manuals and I recommend you purchase a manual if you intend to work on any motor other than change spark plugs or gear oil.  My articles may explain examples (& many times way beyond the manual but not does not replace it) of what you will run into. But again are not meant to replace the manual.  You can many times purchase manuals off eBay.  Also there are good repair forums on the internet, one being iboats.com however, please first use the FAQ sections or do a search of the forum for your problem.  In all probability your issue has came up many times before.  And if you do ask a question, be specific as to the make, year, model & hp of your motor AND give a history of repairs if any plus a detailed situation you are experiencing.  Also when you log on to ask a question, use a descriptive header line, not just "PLEASE HELP" .  If you get no response in a few days, change the title & reword the question for better clarity.
