Hi all,<br /><br />I have an Evinrude 55HP 1979 model which I purchased about 1 month ago. The engine has no troubles starting, idles fine and when put into gear there is no problem...that is, until engine warms up and turned back on. It idles fine, but when put into gear, stalls. This will happen about 6 or 7 times until I finally retrieve the boat onto the trailer. I've checked fuel lines and have adjusted the idle to set it a bit faster, but still no go. I have also changed the sorts of fuel I've been using. A mechanic told me that because the engine is so old, it may be on it's last legs and that this problem can't be fixed. Whould this be true? He may have been trying to sell me a new engine which I can't afford to do right now. Any ideas to my problem?<br /><br />Regards,<br />John.
