J88 OWNER MANUAL 35
Engine System
The engine and fuel system is engineered to be conveniently accessible for repairs and general maintenance.
Located aft of the companionway ladder, there is access to the forward and sides of the engine and saildrive
systems via removable access panels.
Before starting the engine read the engine manufacturer’s owner’s manual for proper break-in and operating
procedures. Once the engine is running, inspect it for any discrepancies, like oil leaking, excessive water
leaks, or anything out of the ordinary.

Engine Control Panel: is mounted aft on the starboard side of the cockpit. It contains the start & stop
buttons, warning lights, and tachometer. The combination throttle/gearshift is also mounted to starboard.
Double-check all mechanical connections between engine and on-deck equipment.

Engine Bed: is constructed of heavily reinforced fiberglass. The engine sits on rubber shock mounts to
help isolate the engine vibration from the boat. Check to see that the engine is sitting correctly on these
mounts and the bolts tightly secured.

Neutral Safety Switch: the J/88 is equipped with a neutral safety switch and the engine will not start
without the throttle control in a proper neutral or advanced neutral position.
Sail Drive
The J/88 is equipped with the Yanmar SD-20 Saildrive. This system provides a clean quiet alternative to
conventional yacht drive trains. We recommend that you follow all Yanmar guidelines included with the boat
for maintenance and service of this system.
Fuel System

Fuel Tank & Hoses: The J/88 is equipped with one 15 gallon fuel tank located aft of the mechanical
space behind the engine. Fuel lines run from the tank to the fuel primer pump. From there fuel flows into
the injectors on the engine. The tank is built of polyethylene and vented overboard. For a layout, please
see the Fuel & Exhaust System diagram.

Fuel Gauge: is located near the engine panel recess in the cockpit. The gauge reflects level (height) of
fuel in the primary tank, not the quantity . Try to maintain a minimum level of 1/3 to 1/2 tank filled at all
times.

Fuel Line Shut-Off Valve: sits atop the tank. Since diesel engines require bleeding after they have been
deprived of fuel, it’s important that the shut-off valve be in the “ON” position (lever parallel to piping)
anytime the engine is started.

Fuel Tank Access Plate: is atop the fuel tank and provides access inside to clean the tank.
Engine Cooling System
The J/88’s engine utilizes both a “closed” cooling system, in which a mixture of fresh water and antifreeze is
circulated within the engine, and a “raw water” system, in which a heat exchanger supplies a constant flow of
outside water, pumped in through the raw-water intake, to cool the coolant mixture.
Coolant system: The filler cap (it looks like a radiator cap) for the freshwater-and-antifreeze cooling system is
located on top of the engine manifold. Check the coolant level of the manifold and the coolant sub-tank aft of
the engine, (check when the engine is cool). When adding coolant, follow the engine manufacturer’s
recommendations for the proper fresh water/antifreeze ratio. In climates where freezing may occur in winter,
test the coolant mixture for freezing point. Add coolant as needed if the system is not drained for winter
storage.
