I am planning to fit an additional manual bilge pump in my 439 as a back up. I had one in my last boat, where the pump was mounted discretely inside a locker with a permanent outlet skin fitting, but with a longer roving inlet hose. Never had to use it in anger but was a good safety feature.
my 439 has a manual pump in the cockpit and 2 electric (usual jeanneau set up) so would be in addition to that. Existing manual pump and the electric ones only have (I think) 1.25 inch bore pipes, I would fit a pump with a 1.5 inch bore
Anyone else done this in a 439 or similar? Interested to know where you put it!
