how to take cover off 1979 mercury boat motor
How old is my Kiekhaefer Mercury 7.5 boat motor Serial number 3374590
location of VIN # on a 1999 Tracker boat motor?
I would say 50 H.P.
1978
1977
Mercury 3.9 HP. Single Serial Number 1657514
If it runs perfectly, starts easy, etc, probably around $700-$1000. If something is broke and/it is missing parts or incomplete, $200-$400 as a parts motor.
the boat is a excellant aluminum boat. I dont have anything good to say about mercury though
Unfortunately to find out the year of a Mercury boat motor one needs not only the serial number, but also the horse power rating. This allows it to be narrowed down to a specific year.
On the 9.8 hp Mercury, set the maker points to .020 in.
