separation of fluid in the bottom. (Water is heavier than diesel fuel and will 

collect at the bottom of the glass bowl if there is water in the fuel.) IF YOU SEE 

CONTAMINANTS OR LIQUID SEPARATION, you want to remove them 

without

 removing all the fuel in the glass bowl:

 

1.

 

With a collection container in place (stored behind the generator), open 

the black drain by partially unscrewing the valve at the bottom of the 

glass unit to evacuate just the water or contaminants, and then 

quickly

 re-

tighten the drain.

 

2.

 

If the vacuum gage at the top of the filter approaches the yellow range at 

cruise power, the filter should be changed.  Please advise San Juan 

Yachting if you should observe this condition. 

3.

 

The Generator has two fuel filters.  One mounted on the aft port bulkhead 

and the other  on the engine itself.  The are changed out each season and 

require no other maintenance.  Spares are available in the spares bin if 

needed. 

 

Complete a visual check of the engine room

 for leaking oil, fuel, or coolant, loose items that 

should be secured, or anything unusual.  

 

 

Verify that all seacocks are open, especially the 

main engine cooling seacock. They should be 

in the open/vertical position

.

 

 

Make sure that the 

SEAWATER STRAINERS for the engine and generator are free of 

seaweed or debris

. The engine sea strainer is a large bronze unit with a glass-enclosed section 

that houses a strainer. It is mounted aft of the engine near the engine room entrance and is 

connected to the seacock with a large black hose

 

1.

 

Using the flashlight, which is stored in an open box on the aft bulkhead next to 

the toolbox, 

check to see if the strainer is clear and not plugged with seaweed or 

debris 

before every start.

 

2.

 

To clean the strainer, close the seacock (lever horizontal), unscrew the top with 

the 

flat bar 

laying next to the yellow tool box, lift out the basket, swish it back 

and forth in the orange bucket filled with clean water, and then reinstall it. There 

is an orange bucket in the lazarette that can be filled with clean saltwater.  Use 

the bucket to prevent dropping the strainer overboard!

 

3.

 

REOPEN THE

 

SEACOCK

!!   

4.

 

Note:

  We have rarely experienced the need to clean the strainer.  Avoid 

driving

 

through large patches of sea grass and you should be fine. 

5.

 

Make sure that the 

seawater strainer for the generator is free of seaweed or 

debris. 

Use the same procedure as above.  It is a smaller unit similar to the 

engine strainer and is located on the left side (facing aft) of the generator.

 

6.

 

Remember to 

REOPEN THE SEACOCK!!

 

 

When you have completed the engine room checks, turn off the engine room lights at the office 

station breaker panel labeled BILGE LIGHTS.  Failure to do so may needlessly deplete the 

batteries. 

 

 

 

DISCONNECT SHORE POWER 

1.

 

At the OFFICE STATION breaker panel, turn OFF the main AC gang breaker labeled 

SHORE POWER. All remaining AC breakers may be left on.
