4 Stroke Weight vs. 2 Stroke on Bracket

[joe7670]

I keep reading about the concerns of putting a 4 stroke on a bracket due to weight.

I'm looking as yamaha's website and the 150 4 stroke is just 40 lbs. more that the same size 2 stroke model.

Am I missing something with respect to weight that they are not displaying on the specs sheet?

I was almost convinced that I had to go with 2 stroke just from reading posts, but if I can, i'd really like to go 4.
