DENALI 28
Freshwater Cooling (Optional)
Installation of “Freshwater Cooling” provides adequate engine cooling without exposing the
internal engine cooling system to the harmful effects of surface water. This system is optional with
gasoline stern drive engines on the Denali 28. The engine owner’s manual provides additional
information regarding service and maintenance of this equipment.
SHOULD AN ENGINE INTAKE OR AN EXHAUST OR COOLING HOSE RUPTURE, TURN
THE ENGINE OFF IMMEDIATELY. PROCEED UNDER TOW IF NECESSARY, TO A SER-
VICE FACILITY FOR APPROPRIATE REPAIRS. MAINTAIN A CLOSE VISUAL WATCH ON
THE PROBLEM HOSE AND THE BILGE WATER LEVEL.
1.5 Propellers
The propellers convert the engine’s power into thrust. They come in a variety of styles, diameters
and pitches. The props that will best suit the needs of your Denali will depend somewhat on your
application and expected average load. Most propeller sizes are identified by two numbers stamped
on the prop in sequence. The 1st number in the sequence (example 14 x 21) is the diameter of the
propeller and the 2nd number is the pitch. Pitch is the theoretical distance traveled by the propeller
in each revolution. Always repair or replace a propeller immediately if it has been damaged. A
damaged and therefore out of balance propeller can cause vibration that can be felt in the boat and
could damage the outdrive gear assembly. Refer to the engine owner’s manual for information on
propeller removal and installation.
Note: Before changing propellers to correct boat performance problems, be sure other
factors such as engine tuning, bottom and running gear growth, etc. are not the
source of performance changes. Always be sure the load conditions are those
normally experienced, before changing propellers.
RUNNING AGROUND OR STRIKING AN UNDERWATER OBSTRUCTION CAN RESULT IN
SERIOUS INJURY AND DAMAGE TO THE DRIVE SYSTEM OR BOAT. IF YOUR BOAT
RUNS AGROUND, EVALUATE THE DAMAGE THEN PROCEED AT LOW SPEED TO THE
NEAREST SERVICE FACILITY AND HAVE AN IMMEDIATE INSPECTION MADE BEFORE
FURTHER USE OF THE CRAFT. A DAMAGED BOAT CAN TAKE ON WATER. KEEP
ALL LIFE SAVING DEVICES CLOSE AT HAND WHILE DRIVING TO A DOCK AREA. IF
THE BOAT CANNOT BE IMMEDIATELY REMOVED FROM THE WATER, THOROUGHLY
INSPECT THE BILGE AREA FOR LEAKS SO THAT THE BOAT DOES NOT SINK WHILE
MOORED.
