J/145 OWNER GUIDE 40
•
The filler cap for the fresh water (closed) cooling system is located on top of the engine manifold, and
looks like a radiator cap. Check the level in the manifold frequently (ensure engine is cool). If
additional liquid is necessary, add only a mixture of anti-freeze/fresh water. In colder climates where
freezing may occur over the winter, be sure to test the coolant anti-freeze/water mixture for freezing
point and add anti-freeze as needed if the system is not drained for winter lay-up. Follow engine
manual recommendations for proper water/anti-freeze ratios.
•
The WATER STRAINER is located in the engine compartment and has a two-stage design to prevent
“clogging” of the cooling system. To clean: Ensure the engine water intake thru-hull is closed. Check
that the lever is perpendicular to the intake. Unscrew the wing-nuts atop the filter and remove the
strainer from inside the glass case. Wash thoroughly with water or replace with a new one if badly
soiled. Replace strainer into case and tightly affix lid with the wing-nuts.
Exhaust System
The J/145 is equipped with a water-injected exhaust system to cool the exhaust. It is designed to both
dissipate heat and act as the exhaust muffler. If the flow of cooling water is interrupted and the engine
overheats severely, the rubber hose coming from the engine exhaust elbow may melt. Always check this
hose after any overheating incident. It is good practice to accelerate to 2000-2500 RPMs after idling to flush
the system just prior to engine shut-down. This clears most exhaust water from the muffler. In fall de-
commissioning, the muffler should be drained using the drain plug, or anti-freeze added to the pot so residual
water doesn't freeze. Remember, if the engine does not start after a prolonged period of cranking over
(starting), be sure to drain the pot or exhaust loop. Water may accumulate here and fill enough to flow back
into engine manifold and cause damage.
General Hints To Avoid Problems
•
Monitor brightness of cabin lighting and charge batteries as required by running engine. Batteries are
charged by either the AC battery charger or by running the engine.
•
Stop engine with throttle fuel cut-off, then turn ignition key “off”.
•
NEVER turn engine battery switch to OFF position while engine is running.
•
For best efficiency and fuel economy a cruising R.P.M. of 2,800 - 3,000 works well. Vary RPM levels
periodically when cruising under power for a long distance. Be sure to thoroughly read and follow the
manufacturer’s manual for proper break-in procedure for the standard Yanmar Diesel engine. When
not underway, battery charging and refrigeration cooling should be handled via shorepower or an
auxiliary generator.
•
Do not run engine at full throttle for sustained periods, as breakdown may occur. Most importantly,
find an RPM that runs smoothly and follow the Yanmar guide. Avoid "vibrating" RPM speeds when
possible.
•
Keep engine gear shift lever in "REVERSE" position while sailing to prevent possible "free-wheeling"
of prop.
