Interesting, I wonder why the difference? mine is from the early seventies,there is no Seacraft factory hull ID # but there is a Massachusetts certified hull number on it that says 1971.
I know very little about these hulls,so I wonder why the different rating.The capacity plate is riveted on and is,I'm sure an original plate.

In 1971, 135 hp was the most powerful outboard made. The 1st 150 hp didn't appear until late 1972. Rating it for 140 simply meant that you could put any motor you wanted onto it, without fear of overpowering it.
