Need Help With year of motor

[pooprprospector]

Wow it seems the motor manufacturers should put the year ON THE MOTOR. It sure would make things easier. Any way the motor is a Mercury 200 (i think 20hp) serial #4405432. Also it say thunderbolt ignition, what is that. I think the pull start rope must be broke cause i cant find it lol. any help is appreciated.

Hope this helps

Almost forgot......
Thunderbolt ignition is just a trade name that Mercury uses,
There where several different versions used, mainly CD (capacitive discharge)
which produces a hotter spark.
I think you may have version 5.
Good luck with it!

capacitor discharge; pointless with a coil per cylinder
