4J1: General Discussion
The main engines on the boat are two Caterpillar 3126 6-cylinder Diesels, each producing a
maximum of 420 horsepower. These extraordinarily-reliable, rugged machines are the top-of-the-line,
and can be expected to give you trouble-free, economical cruising.
On engine start, no long warm-up is required! Three or four minutes is sufficient, then load the
engines by putting the transmissions in gear. Do not run them over 1400 RPM until the temperature
gauges read at least 140° Fahrenheit. Do not run the engines for long periods with the transmissions in
neutral, with no load!
4J2: Engine Checks
The engines require a regular, daily check, since
once underway, you will probably not check them while
in use, tucked away as the are beneath the cabin floor.
Please perform this check each morning (when the
engine room is cool!):
Check The Oil
The oil level should be between the two marks
on the dipstick. The dipsticks are located on the aft
inboard side of each engine, low on each crankcase.
Use a paper towel from the roll provided, wipe the stick,
reinsert, and take reading.
The distance between the two marks is about 1.5 quarts. Add
only enough oil to bring it up above the "add" mark, say a quart, using
the oil provided on the boat, Shell Rotella T SAE 30. (If you need
more oil, buy it! We will reimburse you.)
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
Coolant is in the tanks on the forward top of each engine; check when the
engine is cool. There are expansion tanks for each engine. Check that the
fuild level remains betweenn the uppper and lower markings.If coolant is
needed, add 50-50 premixed coolant to the expansion tanks. Do not overfill,
leave room for expansion!
Coolant should be needed rarely; if it is, find out why!
