Hand pump
Mount in cockpit seat, in an area where can be operated without interfering with helmsman. Mount midpoint and up so youÕre not working it next to the floor. Intake would be the lowest area of the hull, just about dead center of the keel trunk, either side. Discharge would be through the stern, above the waterline. You do not want water entering the system from the outside or have to push water against outside water. http://www.catalinadirect.com/index.cfm?fuseaction=product.display&Product_ID=529
