Got this from Jeff ...
Gregg do you have any idea what this is?
Could you post it on the cgomn site with that question?
One of the supervisiors at work (my neighbor) his brother aquired it as a purchase of a cottage on Gull Lake. He is going to sell it. The motor was overhauled in 96 and has been ran since. Boat was put away in 96 in storage (garage).
Not sure on the boat, but if you get the first three letters from the serial number we could tell ya.
I do know that if the motor really is an XS it's one cool motor !
Serial number on motor will tell forsure ...
