exchanger to cool the engine and then expels it through the
exhaust system to keep the pipes cool. If the pump fails, it could
severely damage the engine. If something smells “hot” or the
overheat alarm sounds, investigate at once! There should be
no steam or water spraying in the engine room.
If a pump seems to have failed, the usual causes are:
• Plugged intake. Is there plastic wrap, seaweed, jellyfish or
other obstruction present?
• Clogged sea strainer. Is there debris in the sea water strainer?
• Failed impeller in the pump itself?
Troubleshooting problems takes only a few minutes:
1.
Turn off the seacock for the engine.
2.
Take the top off the sea strainer. Save the gaskets!
3.
Open the seacock valve to make sure it is clear (water won’t
gush in but will start to overflow the strainer, a plastic bag and /
or towel is handy to capture the water while you are confirming
water flow).
4.
If the strainer is clogged, rinse in a bucket with clear water
and a hose if available. You can also rinse it in the sea but
don’t let go, it won’t float and operation without it in place will
damage the engine.
5.
If seacock and strainer are clear, the problem is likely the
pump impeller. Time to call for help using the emergency
contact list in the Owner’s Manual.
Fuel
Fuel is contained in two 162 gallon tanks located aft of the
engine room.
Fuel crossfeeds from the port and starboard tanks to a common
manifold and then passes through either a port or starboard
Racor primary fuel filter (shown at left). Racor primary fuel
filters are mounted on the aft wall of the engine room, port
side. A lever on the face of the support brackets determines
which filter is in use.
The engine pre-start procedure includes a visual check of the
glass bowl at the bottom of the filter to ensure is has just tinted diesel fuel, no
visible debris or clear liquid. If either are noticed, there is a fuel contamination
issue. Time to call San Juan Sailing for assistance.
Shaft Logs (Seals):
A shaft log is a watertight fitting that prevents water from
coming into the boat around the hole where the propeller shaft exits the hull.
Osprey is fitted with an excellent shaft seal. There should be no need to adjust it. If
there is any sign of water seepage/dripping, contact San Juan Sailing immediately.
