4J: Engine & Transmissions

4J1: General Discussion

The main engines on the boat are two Cummins 330B “Blue Diamond” Diesels, each producing a maximum of

315 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 Checking

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 inboard side of each

engine, toward the forward end of the engine itself, and the

stick “pulls out” upward. Use a paper towel from the roll on

the forward bulkhead, wipe the stick, reinsert, guiding the stick

with the towel to keep from bending it, 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. (If you need more

oil, buy it! We will reimburse you.) The oil fill on each engine

is a cap in the forward valve cover on each engine. Unscrew

and remove. After reinserting, be sure to tighten the cap, but

do not over-tighten.

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.

Oil fill cap is on the top of forward-most valve cover.

The yellow T-handle is loosened then the

dipstick is pulled on each engine for oil checks.
