Thank you for your reply, the HP is 7.6 Mercury Thunderbolt In order to determine the year model for a Mercury outboard, in addition to the serial number, the engine horsepower is needed as well.
Mercury Marine classifies year model by serial number range. For example, in 1973 Mercury produced the 50hp starting with serial number 3478003 and ending with serial number 7007358, thus 50hp serial number 3576839 would be a 1973 year model. Most any reputable dealer or repair facility should have these model year charts on hand. Also noted, when looking up Mercury year model, you will need to know both serial number and horsepower, other manufactorers, OMC for instance, only needs the complete model number I have a 50hp mercury motor sn# is 3576839. I can not find out the year,I needit to find parts.
An 85 hp Mercury outboard, serial number 3858432, would be a 1973 year model.
the serial number is 6548158
The blue stripe 4 cylinder 50 hp Mercury outboard was produced in the early to mid 1970's. The serial number 3350793 would be a 1972 year model.
In addition to the serial number, the horsepower rating is needed to determine the year model.
