Thunderbolt 800 - 1975 or 1972

[hartleck]

I have a Mercury Thunderbolt 800 that has the year 1975 on the title but when I look up the stamped Serial Number on the motor...(see Attachment) ...it falls in 1972 on the ID Charts. I'm confused and not sure how to order parts. Any ideas?:redface:

hartleck;

Does the data plate s/n match the s/n on the powerhead?


It comes up as a Model 1800101:


800 (80.0) 2986444 - 3186282 1971

I've have three of those motors (2 parts motors and 1 running), and on each of them there is a SN stamped elsewhere on the powerhead. One motor has the SN stamped into the distributor mount casting, and the others have the SN stamped on the starter motor mount. Check there to confirm if the two numbers match.

What color is the accent trim on the cowlings? I think they were red until 1972, then changed to blue in 1973.

The title denotes the year of the boat not the motor.Any year can be on any boat.J

Yes the powerhead # is the same

This was helpful. I found the # on the distributor mount casting. I have red trim

The title denotes the year of the boat not the motor.Any year can be on any boat.J

In Texas we have to title separately both boat and motor and the title for the motor does carry the motor year. Such is the case on my 2010 Veranda and 2009 Yahama 115. This is why I was confused.

Thanks all for the help. I'm sure I will have many more questions to ask if that is OK.

Didn't realize Texas did that.All the places I've lived the boat had the year and no one cared about the motor.J
