Evinrude 90hp on 1975 Glastron 156?

[Justinkdickinson]

Ok so I bought a 1990 Corsair Sunbird for $1000 and the Evinrude 90hp runs great. I knew there was some soft spots on the floor so I got in there. It’s not looking very good as the stringers might be rotten. The plywood is rotten but haven’t got down to the stingers yet. My neighbor has this 1975 Glastron 156 for $250 with no motor in great shape. Instead of the hassle of replacing potentially the whole floor, do you think this 90hp will be too much on that Glastron!? I know the limit is 85 the manual says. Thoughts?

The 90 is heavier than a 1975 model 85 HP Evinrude.-----The 90 HP is also prop rated.
