[C320-list] Exhaust question

[Bob Borelli]

What could be leaking water into the bilge so that pump runs every 15 minutes?

Water from exhaust only when engine running could be:

  *
Exhaust elbow and or gasket
  *
Exhaust hose to Muffler
  *
Aqua Muffler
  *
Exhaust hose from Aqua Muffler to overboard discharge.
  *
Raw water pump cover gasket
  *
Raw water pump supply hose.

Fresh water system use food color in tanks to locate possible leak:

  *
Forward, Aft, Hot water tank connections.
  *
Quick Connect 'Whale' water tube connections
  *
Water filter cannister
  *
Water pump
  *
Accumulator tank

Sea valve hose connections:

  *
Raw water supply to diesel
  *
Galley sink drain
  *
Head sink drain
  *
Shower sump pump drain
  *
toilet raw water intake
  *
Holding tank ovbd discharge

Miscellaneous:

  *
Ice melting in the reefer drains to bilge
  *
Shower water to sump pump hose
  *
prop shaft stuffing box
  *
anchor locker drain hose, if bow down & hose ruptured, ovbd discharge under water, water in.
  *
unlikely leak around keel bolts
  *
if its been raining that is a whole longer list
  *
galley and head under the sink drain connections

Haven’t run the engine that much yet so don’t know. But the other issue is the bilge runs intermittently every 15 min or so - so something is leaking - but maybe that in the water system?-,they are checking on that as well.
