serial number

[msbhammer]

Question of the morning. After court this morning, was gonna hit the boat store and pick up a new water pump, seals and thermastats. Dont know anything about the motor other then being told its a 1986, but nothing I see says 1986. Would any number on the serial indicate the year of the motor ????
My serial number on the motor is A914379. Wanna make sure I get teh right parts. Are replacing the seals on the lower unit a big deal. Have the green lower unit fluid leaking out from under the prop.
Thankx !!
