[QUOTE="heath, post: 474784, member: 23489"] Hi all, I purchased an older gentleman's jonboat and it came with this Johnson 9.9 According to the seller it ran well the last time it was used, apart from a finicky electric starter. Unfortunately, the "last time it was used" was about 2.5 years ago. Motor has been on the boat the entire time exposed to the Illinois elements. I finally got off my bum and made a motor stand this morning so I can work on this thing. I've got room underneath the prop for a tub of water. Now it's time to decide what to do next. Based on my searching of this forum, I've gathered the following tips and suggestions: [list] [*]change the spark plugs [*]change the impeller in the lower unit [*]change the lower unit oil [*]get a new gas tank and fuel lines and mix 50:1 with non-ethanol low octane fuel [*]drain the carb bowl(s) [color=#FF0000]<-- I have no idea what this means[/color] #-o [*]give each cylinder a few drops of oil and rotate the flywheel by hand to lubricate both cylinders [/list] Are there any mistakes above? Is there anything else I should do before trying to start the motor? I have the S# and model year written down at home. I'm posting from the office. :oops: [/QUOTE]
