Has anybody ever seen this?
http://www.brokeboats.com/This guy, Wayne Weber, has a marine motor shop somewhere in New England, I think. He provides FREE advice to whoever wants to turn a wrench on their own motor. He helped me out several years ago, and it looks like the site has gained popularity. He still provides the free service, but is now offering unlimited "Express Support" where he bumps you up in the queue fo $9 for 30 days.
Obviously, he's a super nice guy, and even if you don't use his service (free or paid), there's a wealth of information on this site.
