[C320-list] Bilge pump cycling excessively

[Jeff Hare]

I agree with Dick here.  

Also, I *believe* that there is not supposed to be a check valve in a bilge pump line. 

The thing to do is adjust your stuffing box to eliminate dripping when the prop isn't turning. 

Unless you have the GFO packing material, you should get a few drops a minute with the prop spinning running.

If the stuffing box locknut is corroded you may need a few drops of corrosion cutting penetrating oil sitting for a day or so before trying to adjust it. 

I tighten the large nut by hand until the dripping stops, then hold that still and retighten the locknut.

The ultimate way to fix this is to get a PYI shaft seal or use 100% Teflon
for your shaft seal.  Presto a dry bilge.

I'm wondering if anyackone else has seen this and has a solution.

 

Our bilge pump cycles on way too frequently. When the pump goes on, it pumps
out all but about 1.5 inches from the bottom of the bilge. Then some of the
water that it pumped leaks back into the bilge and as more comes in
eventually from the stuffing box, the cycle starts again. I'm guessing
there's not much more than one pint of water before the pump goes on again.

 

 

Does anyone know if there is supposed to be a check valve between the pick
up hose and the bilge pump?
