I am outfitting a Mariner 4 I just bought. My concern is I will need to inflate and rig in lake parking lots and move boat to the water. I will typically be alone for fishing, so the weight of the boat is of concern. Thinking about modifying the motor mount to hold some flip up wheels (as seen on RIB with transoms), but concerned that will put too much pressure on back of boat where the motor mount is attached. Any thoughts, ideas, or advice?
