Hi everyone,<br /><br />I have just aquired a 1977 Crestliner / AMF Muskie 550 with a 1977 Johnson 50hp O/B. I have a lot of work to do on the boat but mainly cosmetic thankfully. I have not attempted to fire up the motor yet but she looks in great shape. It has never been used in salt water and was flushed every year and well maintained. The boat and motor have not been used for about 5 years!!! What should I check, do and or replace before I attempt to start her again for the first time.
