2665 DENALI 20
USE ONLY CLEAN, DRY FUEL OF THE TYPE AND GRADE RECOMMENDED BY
THE ENGINE MANUFACTURER. THE USE OF INCORRECT OR CONTAMINATED
FUEL CAN CAUSE ENGINE MALFUNCTION AND SERIOUS DAMAGE.
1.2 Drive Systems
The inboard engine is mounted in the stern and coupled to a transom mounted outdrive which
does all shifting, steering, and propulsion functions. The outdrive is supplied by the engine
manufacturer and has specific lubrication and maintenance requirements.
Proper engine alignment is very important. This was done by the factory when the engine was
installed and should be checked at the 20 hour check and annually thereafter. If you
experience excessive vibrations or suspect that the engine is out of alignment, please contact
your Pursuit dealer.
ALWAYS RETURN THE ENGINE THROTTLE LEVER TO THE EXTREME LOW
SPEED POSITION BEFORE SHIFTING. NEVER SHIFT THE UNIT WHILE THE EN-
GINE SPEED IS ABOVE IDLE RPM.
Corrosion
Marine growth and galvanic corrosion is a concern if the boat is to be kept in saltwater. Marine
growth occurs when components are left in the water for extended periods and can cause poor
performance or permanent damage to the exposed components. The type of growth and how
quickly it occurs is relative to the water conditions in your boating area. Water temperature,
pollution, current, etc. can have an effect on marine growth. If the boat is to be left in saltwater,
the hull and outdrive must be protected with antifouling paint. It is extremely important that
the proper antifouling paint is used on each component. Contact your Pursuit dealer for
information on the proper paint to use in your area.
Galvanic corrosion is the corrosion process occurring when different metals are submerged
in an electrolyte. Sea water is an electrolyte and submerged engine components must be
properly protected. Outdrives are equipped with sacrificial anodes to prevent galvanic
corrosion problems. The anodes must be monitored and replaced as necessary.
On some outdrives, the anode may not provide an acceptable level of protection when a drive
is used in freshwater and a magnesium anode must be used. A magnesium anode, when used
for combined operation in both fresh and saltwater, or water with a low salt content, will
deteriorate quicker and must therefore be replaced more often. For recommendations
regarding corrosion protection for the engine or outdrive, please refer to the engine owner’s
manual.
