In my opinion, the OP is on exactly the right track. This pump:
HondaWSP100 Model Info | Submersible Water Pump | Honda Pumps
For example, moves 150 gallons a minute (nominally) of debris-filled water on a 1 hp motor
needing 47 amps of startup current
@ 110 volts, and 11 amps to run, demand well within the capacity of average sized generators and inverters.
is required; just store it with a roll-up fire department type hose and Bob's your uncle.
I think this is an absolutely superior solution to the nightmare of needing to dewater the boat after a major leak. Don't forget that in major flooding incidents bilges typically fill up with debris, which often clogs normal bilge
pumps, adding yet another problem to an already crisis situation. A big trash pump is just the dog's danglies for such a cash.
As others have said, you dramatically improve your chances of finding and fixing a leak if you can keep the water under control for a while. This is the way to do it. I suppose not that many boats sink at sea because of leaks
, but it happens every year, a $1000 or so worth of gear
with no installation
required seems like cheap insurance
The downside of electric
is you need for your boats electrical
systems to be working. If you don't have a generator
, then this is worse, since flooding can kill your battery
If you do have a generator
, however, then how much more likely is the generator to be working, than a gasoline engine
which is run infrequently? Are you ready to run your emergency
dewatering pump every couple of months, keep the carb clean, etc.? A device you will likely never use and will just be in storage
for years and years? Even a diesel
dewatering device will need regular operation to maintain reliability
. I would much rather rely on my generator, which I use constantly and keep in top condition, as the power source. Backed up by inverter
and batts or inverter
and main engine alternator
-- fully three power sources for the pump, which can be stored without maintenance
for years. This is the best way to do it.
