What year is this mercury and maintenance

[Boatinjones]

I just got this 9.8 thunderbolt and the serial number i found was 4131116. I can not find what year it is anywere. Also if anyone can give me some tips on how to take care of it or what i should watch for would be great. I will be running it in salt water alot and i do understand I have to rinse it real good when I'm done. Any other advice would be nice. This is my very first outboard ever, so even if you have something you think is stupid to post it will help me cause I know nothing on this. Thanks

Welcome to iboats.

1975

Be sure to get a repair manual and do all the proper maintenance. I would change the impellar now if it has not been done, change the spark plugs, and clean out the carb.

Great motor if properly maintained

We actually have a dedicated Mercury Outboard repair section here on iboats!

Thanks Bob took it out today in the 8 ft dingy. Man it moves good. Thanks again I will look into the forum for more on this motor.
