Great! When your boat is taking on water, simply disconnect the hose, fill
it with water, give it a few pumps to get it going and then go back back
and reconnect the hose. Scuba gear is helpful here as the hose connection
could be WAY under water.
I have serious reservations about these pumps. I tried mine one day and
found, like most of you probably would, that it wouldn't pump at all. I
had been living under the delusion that it was ready for an
emergency. When I took the pump apart the aluminum valve seats were pitted
and eaten away. Most of these pumps are aluminum, which is a terrible
choice for a salt-water pump.
If you test them from time to time you're only introducing salt water which
will destroy them, and if you don't test them you never know whether
they'll work. I replaced my pump, but smeared grease over the entire
inside before installing it. I keep testing to a minimum, and only pump
fresh water through it.
