Observe  the  readings  of  the  gauges.    The  oil  pressure  will  register  about  37  PSI.    The  engine  temperature 
should rise slowly.   
 

Note -- If oil pressure is low, shut down engine, and inspect engine compartment and look for possible cause 
(for example, loss of oil.)    Caution -- If an engine is overheating or there is lack of raw water expelled in 
the  engine  exhaust,  stop  the  engine  immediately.    Recheck  the  raw  water-cooling  system  to  ensure  the 
seacock is ‘open’ (handle in-line with valve).   Next, check the raw water strainer for debris. Remove the 
strainer,  clean,  re-assemble,  and reopen the  raw  water  intake valve  (seacock).    Restart  the  engine  and  re-
check water flow from the exhaust.  If water is not flowing properly, the RAW WATER PUMP may need to be 
serviced. Seek help. 

 
Operation

       

 

260 HP Yanmar engines are very reliable.  Optimal cruising speed is obtained at 2000 RPM which will result 
in about 8 knots with fuel consumption < 3 GPH at this cruising speed but is highly variable based on tides, 
wind and loading of the vessel.  

DO NOT EXCEED 3000-3500 RPM

 on the engine.  Running at 15 knots 

will  increase fuel  consumption 

DRAMATICALLY

 so  slow  down  and  enjoy  the  cruise!  Most  destinations 

are fairly close together in the San Juan Islands.  

 

 

To avoid the possibility of sucking air or sludge when the fuel level approaches 1/4

th

 of a tank, refuel 

when the fuel drops below half full and before it reaches ¼ full. 

 

Engine Overheating: If the buzzer sounds while the engine is running, about 999 out of a 1000, it is 
no more serious than eelgrass plugging up the raw water strainer.  The best solution to this problem 
is  prevention  keep  an  eye  out  for  eelgrass  mats  especially  along those  “soapy”  looking  tides  and 
eddy lines in the water.  And don’t run over it.  When eelgrass gets sucked into the engine cooling 
water intake, it jams at the raw water strainer. 

 

To clear the eelgrass from the raw water strainer, stop the engine, open the engine hatch, close the 
RAW WATER SEACOCK, unscrew the clear bubble top of the strainer, remove the foreign material, 
screw the clear top back on the strainer and open the RAW WATER SEACOCK.  Restart the engine.   

 

If upon restarting, the engine overheats again, check the strainer to make sure it is drawing water in 
to about ¾ full.  If not, grass could be plugging the opening in the hull.  This requires diving under 
the boat to clear the eelgrass, so you should contact Ship Harbor Yacht Charters. 

 
 

If the above fails to solve the problem, contact Ship Harbor Yacht Charters for assistance. 

 

There may be other reasons you hear the buzzer. If you lost oil pressure, the oil icon warning light 
will light up, so check which light is showing red.  If it’s the oil light, shut down the engine, check the 
oil level and contact Ship Harbor Yacht Charters. The alarm buzzer is more likely to indicate engine 
overheating, and the temperature icon light will light up.  Before you shut down the engine, check for 
water gurgling out the engine exhaust.  If you have a “wet exhaust”, check the coolant level in the 
overflow reservoir bottle and if no coolant is seen, add enough coolant to reach the “full” line of the 
bottle.  Check the bilge for coolant.  If coolant is found, contact Ship Harbor Yacht Charters.  If the 
coolant  reservoir  bottle  is  full,  check  to  see  if  the  engine  threw  a  belt.  Without  a  belt  on  the  raw 
water pump, the raw  water  won’t circulate and cool the engine.  (Replacement belts are located in 
the  engine  spares  kit.)    One  other  possibility  is  the  impeller  in  the  raw  water  pump  has  failed.  
Impellers  are  replaced  each  spring  but  it  is  still  possible  that  a  hard  object  may  be  drawing  and 
break off an impeller blade. (A replacement impeller is found with the engine spares.) Contact Ship 
Harbor Yacht Charters if you suspect you have an impeller problem.
