This is a mod i have done to my last three inboards.The factory locates the bilge pump under the motor on a riser block and not directly in the bottom of the hull.If you leave your boat in the water or on a lift like I do their is always some water in the hull.I made a plate which mounts to the bolts that hold the rudder,bends down to the bottom of the hull and mount a bilge pump to it.I ran a second outlet hose out the back of the boat.I wired the new pump into the existing wiring for the front pump.The second pump keeps my hull virtually dry .My boat is a 2003 and still has the original steering cable and still turns easily. I believe the rear pump keeps water from getting into the steering cable and keeps the hull a-lot cleaner. Plus I like the idea of having two pumps.
