mounting plates new merc vs old

[bruce gagnon]

I currently have a 1990 40 hp 2 stroke outboard that I will be replacing with a 2001 50 hp 2 stroke (3 cylinder) .... are the mounting plates for these two motors different? If so what do I do with the old holes? I have a lowe 160 with a metal transom

thanks
Bruce

it is best to use 3M 5200, and wooden dowels to fill the holes. the use Marine Tex over it inside and out.

chances are, that no they are not different.years ago they standardized the mounting patterns.
