My boat has the picture #5. Well when i recently got the minnkota trolling motor, it had a different one but my mechanic spliced and wired to the existing 4 prong because he said it was much better than the one the new trolling motor came with. That sucker goes on tight and won't budge so i've never had a problem with my trolling motor plug popping out of place. Mine is different than that pic #5 in that the female receptacle does not have exposed connections like a 110 receptacle. It is round, came with a faceplate and has a rubber cover to close the receptacle when unplugged. See my original photo again. I don't like the exposed wiring on the one in the photo #5.
