So I did a stupid (and expensive) thing today and accidentally drilled a hole in the hull below the waterline in my 1983 MK I. Luckily the bilge pump kept the water at a reasonable level for the short time I needed to get the boat hauled out. It was almost certainly a losing battle, but the water didn't rise above the bilge and I had the shower sump pump turned on as a backup in case the water got to that level. This ordeal got me thinking about the other pumps on the boat that might be useful in emergency situations if the bilge pump failed for whatever reason or could not keep up.
I'm considering splicing in a T junction and additional ball valve between the engine water intake seacock and the engine water filter. I'd run a hose from that ball valve into the bilge. In emergency situations, I could shut the seacock and open that valve to use the engine as an additonal pump.
I'm very interested in hearing others' thoughts on this. Is this a bad idea?
