Please identify this boat by serial number

[model14]

I am looking at a 18/19' Sea Ray bowrider of probably mid-80's or earlier vintage to restore. It is powered by a Mercury 1150 outboard. The serial number is:

SER9680V0477 1870 B051 - 7

Please help me decifer the serial number. It sits on a 1985 Load Rite trailer.

Thanks,
Richard
