I hear you, I have a 6 for my dink and it will not get it up on plane.
Had a nice 15 hp but someone stole it while we were on a regetta and
broke the mounts trying to get it off the dink.

If I were you Id get a 25 hp. Gets 4 adults up on plane, great for
running up to resturants while anchored out.

How long is it, How heavy is it, how small does it fold?
Do they have a way of putting a steering console on it?
You gettings davits?
