So weird. I was just looking into this last night.
We have a Seahawk 4 and while Googling this exact subject, and found this:

Check the 1st comment to see the mod he did to it. I thought it was cool. Not floating down the bow cool, but still cool.
Back to the motor: I'm not sure what model of the Seahawk you have, but I'd check to see what the max motor weight is. Mine says I can only do a max of 18lbs. Can you even get a motor that light that will still push the boat with 2 adults?
I'm not boat savvy and don't know if it really makes a difference anyway and was just going to go to Cabellas to ask. Glad you posted this though.
TL;DR: my post is pretty much useless, but the mod in the link above looked fun.
