My fishing boat is trailered because I need to be able to access different places depending on the bite and wind. I live on the broad lake and if a strong west wind comes up I wouldn't be able to launch a 16' boat but can trailer to a spot on the lee side of the island and enjoy more calm water. When I get my boat on the trailer I get in and pick up the 70 qt cooler which when fully loaded can hold almost 100 pounds of fish. I sit it on the gunnel on top of another smaller cooler then get out and it is at chest level and I slide it off the boat and stagger to the open tailgate keeping it tight against my chest.It is really easier than it sounds. In this case I wanted to get some pure gas for the big boat and they have pumps at the fish shop dock that is about a buck cheaper than the marinas. I muscled the cooler into the glastron which was on the lift from my dock and that is where I did it. I don't usually do it that way so wasn't prepared for the twisting and lifting while bent over. I got the new bilge pump installed this morning. Went OK but I know I am not all that dexterous using my left hand bent backwards screwing in the auto float. The new pump worked great on both auto and manual. I owe myself a cold beer for that little project.
