Motors are AWESOME! Specially in breezes or wind. Bad thing is, once you start using one, you may REALLY like it
The boat you bought however was designed for rivers and not for a motor. The huge rockers leave very little pontoon in the water. Meaning smaller weight capacity, and you will need to slide the frame as far as you can forward to put a battery and a motor on. Otherwise, you will be very butt heavy and tracking is not as good.
Note, If you do use an electric motor, take the bolt out of the head and turn the head so that it is facing the same direction as the prop. Pontoons PULL much better than push. Steer with your feet/fins
You got a fair boat, but watch the frame for cracks. The nylon cover is not as durable as the PVC coated ones. Do NOT transport it full of air. When you get to location, put the boat IN tthe water while you get ready, then top it off with air.
I use hip waders on my Pontoons. So much nicer and easier. I have two framed pontoons, one U pontoon, onr two man closed end pontoon and one smaller 8' closed end pontoon.
Nice thing about my frameless is the two man weighs about 35 lbs.
I started out many years ago with a car tire, then a donut, then the U tubes, then the V tubes and I even put a motor on all those
Now I am pontoon city...LOL
