Could some one please advise me what the age of a Mercury Thunderbolt Ignition 850 serial 7016828? I do believe it to be a Canadian motor probably around 1973- 75
Thank you very much for any help.

1975 and earlier 850s had distributor ignition. I do not believe 850 were made after 1979. They were 800s then.

The maxrules site will give serial numbers and years. I think they have Canadian serial numbers.
