I believe it is a 1980 or 81 Mercury 9.9 but not sure and would love to have more stats on this, let alone the proper identification to get rebuild / tune up parts...<br /><br />Here is the SN : OB296172<br />I BELIEVE the B is a b and not an 8...sure looks like it..<br /><br />Thanks!<br /><br />S
