Yamaha weight help

[Dank Xploidz]

I have a 94 duracraft 1542, I am looking at a 2002 yamaha 4 stroke 25, it weights 180 pounds, that is the same as a 2009 50 hp yamaha 2 stroke. Will my trandsom be able to hold the 4 stroke? when my boat was made I dont think it was intended to have a 25 on there that weights that much.

Help me out here
