smuckey/41,
1988 merc. if not oil injection (probably not) when you ran it last if you did not disconnect the fuel line and run gas and oil mix out of carbs they stand to be gummed up unless you are lucky. How long has it been since you used the motor?? was the fuel treated for storage?
Given all the above I would change lower unit oil! Make sure I had fresh fuel! ( or fuel & oil mix ) If oil injection check oil. If all checks out put her in the water and give her a spin. Good Luck![]()
