Has anyone got an engine driven pump? A boat I once did a delivery trip on had a massive centrifugal pump fitted on a dog clutch to the main ( 100 hp I think ) engine. I recon in an emergency it could have kept the boat afloat after hitting a container, or at least as long as the diesel lasted!
Magic fun for season opening cruises when fitted with a fire hose!
My last boat didn't have a seperate engine driven pump, but did have a twin impellor, one of which could be operated via a valve to an attached strum box sitting in the bilge and then overboard.... reasonable volume was possible from testing... engine was an old Albin AD2
tango four.
What would you recommend as two big electric pumps.
I have a rule 500 with a remote float switch.
But would like to fit a pump which does not have to be in the bottom of bilge, ie could be under cockpit sole area with a suction pipe into bilge and wired through a float switch set slightly higher in the bilge than the switch for the rule 500, so that in the event of any big ingress of water either when moored up or otherwise the remote pump could handle it.
But what LPM or GAL PH, is available and from where?
Cheers.
If you need a bilge pump, you need a 'big capacity' job....
Little ones will do just fine for the odd weep and condensation. If you get a hole somehow, you will want the biggest kit in the catalogue.
As for a manual pump, Patey make/made a big 'un that shifted 120 gallons/min, mounted on an alu baseboard - provided you have enough crew built like the Irish front row. They're still available.

I've got one of these.. http://www.bestmarineimports.com/ERICSON.html
runs as long as the shaft is turning, never used in anger, so far, but the impellor pushes air and so ventilates the bilge. Never seen them offered in UK though, mine is a Swedish boat, bought in Sweden.
Ours is a 32' motorsailer and a few years ago it was calculated that if the / any seacock broke we would need x amount of 'pump out' (can't remember the capacity) but just get the biggest and don't forget bulkheads seperating water! I reckon we have now got the plumbing to have two seacocks fail and still be safe for a while.
We disconneted the engine raw water intake pipe and used the engine to pump out the bilge when Lazy Days sprung a leak. Worked well and saved the day.
I've often though of installing a branch and valves so it would be easier to do in an emergency, must put it on my 'Things to do list' this summer. The Ericson pump looks good just might go that route though.
Agree, they are wonderful bits of kit with spares still available.
I bought an ex GPO one for 65 squids, refurbed it in a couple of hours, and boy ! does it shift water . I did put on an extra length handle to take account of geriatric weaknesses !
The Ericson pump does indeed sound impressive, but it's very big - too big to be fitted in many sailboats. Another consideration is that there has to be quite a lot of water in the boat before it starts pumping, and that you have to be motoring at high revs to get the high output (not necessarily the best thing to do if the damage is the result of running into something).
A belt driven Jabsco with electric clutch, fed from a manifold with connections to all bilge areas and a seacock. It can be used to wash the decks, fight fires, empty the bilge, and also stand in as a spare raw cooling water pump.
