Mercury outboard, 8hp, sn A721731 manufactured in 1987.
If the first digit in this serial number is possibly "A", instead of 4, this would be a 1987 year model 8hp. I do not recall the 8hp model Mercury outboard in production before the A model, in 1986.
An 8 hp Mercury outboard, serial number OD134137, is a 1992 year model.
Why not just place it on a scale and weigh it.
