Merc 850 serial number 6095506. Trying to find year. I've been to a couple sites and can't find this number. The starting 2 digits (60...) look like they've been stamped differently than remaining digits. Not sure if that's normal or if it's been tampered with. Blue strip around shroud, 4cyl.<br /><br />Owner says he can idle around the lake but nothing more, with muffs on it will rev up. Compression in top 3 cylinders is 120. Lots of blue smoke from prop.<br /><br />Planning on ordering manual to help with troubleshooting, but year would be very handy first.
