Where do your bilge pump hoses exit?

Ok,
I know this may sound strange (well it seems strange to me), but here goes.
My C27 has a center bilge bilge pump, which exhausts out the transom, above the water line. So far so good.

It then has a 2nd bilge pump, underneath the port side cabinet (under where the stove is), but it appears that the exhaust hose empties into the aft lazarette - is this normal? Shouldn't this also exhaust overboard, above the water line (probably somewhere on the port beam?).

Then, there is a manual pump mounted in the port side cockpit locker - not a diaphragm pump, but an up-and-down pump (not sure of the proper name - but it's like a heavy duty manual bilge pump mounted vertically). And THAT exhaust hose dumps the water about 3 feet away, back into the bilge...

Any suggestions on how to PROPERLY get this water overboard?
Thanks
Phillip

It sounds like you have a second bilge pump to drain a compartment that does not have limber holes and, hence, does not drain to the bilge on it's own. Discharging that compartment to the bilge, to be picked up by the main pump, is perfectly acceptable. It's more a housekeeping thing than anything else, if I'm reading you right.

The cockpit pump, I would imagine, does not dump the water into the bilge but into the cockpit where the cockpit drains would discharge it overboard. Why anything pumped or drained from the cockpit, or cockpit locker, should go to the bilge is a mystery to me, and probably a sinking in waiting. What does the cockpit hand pump suck water from? What type of cockpit drains do you have? And where do they drain to?

The cockpit locker pump sounds like a navy piston pump, which is not a terrirbly effective bilge pump due to the lack of mechanical advantage and the long stroke. Why it doesn't just drain in to the cockpit, so the discharge can go out the cockpit drains is really odd. Re-routing the discharge hose for this should be relatively simple.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

danjarch will become famous soon enough
The **** pit locker pump sounds like a emergency pump. emergency pumps are not usually do not have a permenant discharge set up. You would be expected to grap the discharge hose and drop it into the cockpit. I also drains into the cockpit to decrease the amount of force needed to pump. A longer discarge hose would slow down the rate at which you could manually pump out the boat in an emergency.
