looking at a old brocure and it says that the 1976 115hp evinrude with tnt weights 269lbs.would it be fair to say that a 1982 90hp with tnt would weigh the same or ever so slightly less?
With power trim it will likely be just over 300 lbs.
My 110 (which is basicly the same motor) has power trim and it weighs 306 lbs according to the factory service manual.
