One of the Tennessee guys has/had a 4 HP on his, and it ran OK but he recently up-sized. I think weight is the issue...if a 4 HP is only slightly heavier than a 3, go with the 4. I bought a 6 HP Merc because it's the largest HP rated for that weight size (57 lbs) and the next size up is comparably a lot heavier. (This is brand new 4 stroke I'm taling about.)
In fact, it's the motor weight that convinced me to buy a trailer for my 15'4. I'm way overweight and closer to 60 than 50 yrs old, and I could load my Highsider into the back of my F150 OK, but it was a bear lifting that motor up into the bed. It was worth the trailer just to have the motor all hooked up and ready to go when I got to the water.
Oh, and my Kayak only got in the water once in the 16 months after I bought the Gheenoe. And that was only to confirm that I wanted to sell it. I put it on Craigslist the next day and sold it.
BTW, I was getting discouraged about not finding any Gheenoes for sale in Tennessee, then one day found one on this forum. Paid $500 for the boat (seven years old) and got a trailer later for $225. Be patient and keep looking.
