Chowder,glade you brought this up.Most small boats don't come with a pump,I've got a 16' lund that didn't and I installed one,I also took a plastic box and cut the bottom and sides out and glued screen over the openings so leaves and debris could not plug the pump,switch on dash,no room for auto switch. I fish alone most of the time,you can't pump and run the boat unless its afoot pump,I haven't checked them out in a while. I had the bottom crack on a 1961 lone star 16' no pump.The only way I had to drain was to stop the boat and pull the plug and get the boat back on plain. If there was any more water in the boat I couldn't have done it. Last summer fishing in a 20' lund we started taking on water,the pump couldn't keep up but we managed to get the boat on the trailer. the intake hose for the live well rotted away.He put in a bigger pump,no room for a second pump.In that case a manual pump would have been great.This is four you guys that fish the finger lakes all winter.I used the boat late in the deer season and it rained like hell on the way home that night and the cover leaks very badly so I got water in th bilge and I didn't pull the plug.went out to put plastic cover on and checked for water ,turned on pump,it was frozen solid. Check it before you leave home.I hope this keeps some one else out of trouble.
