NW Explorations
the seawater flow at the exhaust port at the transom. If the seawater seems constrained, then
the seawater strainer may need to be cleaned.
There are also seawater strainers for the watermaker, generator, air conditioners and
refrigeration systems that you should also monitor.
To clean the seawater strainer
:
1.
Seawater is supplied through two thru hull valves
located under the grate at the forward end of the
engine room.
2.
Close the thru hull valve by turning the handle
perpendicular to valve,
3.
Open the top of the strainer using a wrench which
is in the tool bag,
4.
Pull out the basket and dump the debris into the
garbage. Replace basket into strainer,
5.
Screw the top back into position and tighten to
snub, do not overtighten,
6.
Open the valve at the bottom of the seawater
strainer.
7.
Start up the engine and check for water flow
through the exhaust port at the transom.
8.
Check for leaks at the seawater strainer.
9.
Monitor engine temperature.

Coolant level
Coolant will expand as it absorbs heat from the engines and excessive coolant flows into an
expansion tank. A tank is mounted on the forward end of the starboard engine and the port
engine coolant expansion tank is mounted inboard of the engine near the floor. The level of
coolant should be between the ‘Cold’ and ‘Hot’ level. If the level is significantly below ‘Cold’
then add coolant into this expansion tank. When you conduct the engine room check, inspect
the coolant level in these expansion tanks.
The expansion tank for the port
engine is near the floor
The expansion tank for the starboard engine is
outboard and forward of the engine.
The sea strainer thru hulls and valves
are under the teak grate at the forward
end of the engine room.
