two turns and remove. After reinserting, be sure to tighten the cap, but do not over-tighten.
DO NOT OVERFILL the crankcase (above the “full“ mark), as these
engines will quickly waste excessive lubricant.
If oil is required
often, check under the engine carefully to be sure there is no oil
leak, and if there is, have it corrected promptly.
Check the Coolant Level
The plastic coolant overflow tanks are located above the forward end of
each engine, with caps on the top, and they are quite close to the underside of the
salon sole (floor).
If there is any coolant in the coolant tank
when the engines are
cool, there is enough.
If coolant is needed, determine if there is any sign of a coolant leak under the engine, and if
there is, do not run the engine.
If there is no leak, add coolant to the tank from the jug of pre-mixed antifreeze/corrosion
inhibitor/water supplied on the boat. Choose the coolant can with the pump unit on top, remove the
overflow tank’s cap by turning; insert the tube, and pump until the coolant overflow tank is no more
than one-quarter full.
Visually Inspect the Engine Room
Whenever you’re in the engine room, ask yourself, “Does everything look right?”. Look at the
pads under the engines and transmissions: while some drips are normal, there shouldn’t ever be
substantial accumulations of any fluids!
Check the Sea Strainers Weekly...
...or immediately if an engine runs “hot”.
The engine strainers are in the forward end of the
engine room bilge. The refrigeration sea strainer is just forward of them.
To check a strainer, shine a flashlight through it. While some “fuzziness” from trapped thin
growth is normal, you should see the light clearly on the other side; if obscured, you should clean the
strainer. See below.
4J3: Engine Controls
Patos is fitted with Morse push-pull cable controls with shift and throttle connections from each
helm directly to the engines.
4J4: Engine Emergency Shutdown
In the event the stop switch fails to operate on either engine, you can shut it down manually by
pressing the rubber-encased button on the top of the engine (see illustration). This cuts of the engine’s
fuel supply.
See the illustrations on page 4.22.
