J/46 OWNER GUIDE

NEUTRAL= Between Forward & Aft
REVERSE= Pull Aft
Push in throttle button at center of handle and move throttle lever forward 1/3 to increase initial starting
RPM's.
• Turn ignition key to "ON" position. Audible alarm indicates low oil pressure, and will continue until
engine starts. There is an oil pressure alarm test switch on the cockpit engine panel.
• Turn the ignition key to the "START" position. Release immediately after start. If it does not start in
ten seconds, turn off key. Advance throttle slightly and after ten seconds, repeat.
• Oil pressure light and audible alarm should go out after starting. If not, stop engine.
• Once engine starts, set throttle at about 1,000 RPM. Check for exhaust water
. If no water, shut down
engine immediately. Check to be sure through hull valve to engine cooling system is open, or if the
sea water strainer is clogged. If indications are normal, warm up ten minutes.
• Test forward and reverse at dock with docking lines in place. Shifting should be done below 650
RPM's AT ALL TIMES. Shifting at too high a speed will cause severe damage to the entire drive train.
• Check for exhaust water periodically. Engine is cooled by sea water via a heat exchange and
enclosed fresh water system. Water temperature should be 165 degrees or less and water should exit
from the stern at all times. Without water exhaust discharge, engine will burn up
.
• The best cruising RPM is approximately 2,600-2,800 RPM. Maximum continuous rated RPM is 3400.
Check sea water strainer for debris. Ensure thru-hull is open. If necessary, check under hull to see if
intake is blocked.
• It is best to keep fuel tank 1/2 full (diesel #2) to avoid debris intake and air locks.
Turning Engine Off
• Place throttle lever in idle position (vertical).
• Let engine cool down.
• Push engine stop button on engine instrument panel until engine stops.
• When audible alarm sounds, turn key off. DO NOT use key to stop engine. Do not stop engine with
decompression lever except in extreme emergency. If decompression lever is used to stop engine,
fuel will spray out and accumulate on top of pistons, creating danger of explosion the next time engine
is started.
• When under sail you may hear propeller "wind milling" underneath. After shut down put engine in
reverse gear and it will stop. Because the J/46 engine is so quiet, make double sure the engine is off
before switching into reverse gear.
Fueling the Diesel Tanks
When preparing to take on fuel, the following safety precautions should be followed at all times: Properly
secure the boat to the dock using bow, stern and spring lines.
