J/46 OWNER GUIDE

• Shut off all equipment: Engine, Battery Switch, Radios, Lights, Etc.

• Remove fuel fill plug and clean threads of both plug and deck plate carefully so no dirt falls into filler

opening. Place the fuel hose nozzle into the fill pipe.

• Fill slowly. DO NOT OVERFILL

. Marine fuel expands with an increase in temperature. Thus, fill only

to 95% capacity. If you cannot see the fuel pump, ask the attendant or a crew member to call out the

total gallons. l.

• If fuel tank is overfilled, fuel will leak out the tank vent located on the transom. This spillage should be

cleaned up immediately.

• After fueling, replace fill plate and wash up any spillage. Go below deck and check for fumes or

leakage. Check bilge.

IF EITHER FUMES OR LIQUID FUEL ARE PRESENT, CORRECT THE

SITUATION BEFORE PROCEEDING.

Open all hatches and ports to facilitate ventilation.

• Only after you are totally satisfied that no potentially dangerous condition exists, leave the fuel dock.

Be considerate of fellow yachtsmen.

• In the event of a serious spillage,

STOP FUELING IMMEDIATELY

so he may warn others and wash down thoroughly all traces of fuel or source of fumes.

Engine Maintenance

Check the engine, batteries, and engine mounts once a month. Ensure the engine is fastened securely to

the engine mount frames and look for any problems, such as fuel or oil spillage. If you need help, consult a

professional marine mechanic or a Yanmar licensed repair mechanic.

Run the engine frequently and at occasional high speeds, even if it is not in gear. One reason why sailboat

engines may burn out within a few years is that they are run infrequently and lubricating oil is not thoroughly

and evenly distributed on all moving parts. Be sure to check oil and coolant levels often. If you have any

doubts about the purity of the fuel you are buying, use a strainer to filter out water and dirt.

If there is excessive vibration, in other than specific RPM points, loosen the coupling and insert a feeler

gauge all the way around to determine if the engine is properly aligned. If aligned and vibration persists,

check prop for proper balance and uniform opening/closing and be sure that strut mounting is secure. If

there is still a problem, contact your nearest Yanmar Service Representative.
