BEFORE
CHECK THE TRANSMISSION COOLER FOR DEBRIS
Because this process should be completed while the engine is cool and cannot
cause burns to your skin, we recommend you do this before starting your boat.
Step 1: Ensure the engine is OFF and the engine safety starting switch discon-
nected. Be certain that the throttle/shift control lever is in neutral. Open the engine
compartment. The transmission cooler is located either near the top or on the side
of the engine.
Step 2: Loosen the clamp surrounding the water intake hose at the back of the
transmission cooler and slide off the hose.
Step 3: Check the screen inside for signs of debris. Even small amounts of debris must
be removed to prevent the material from clogging the cooler and preventing it from
functioning properly. The screen is permanently in place and your boat must not be
operated with any foreign materials blocking the flow of water through the cooler.
Step 4: After cleaning, re-attach the hose and clamp.
Important: This is a critical function of routine maintenance. Even clean-
appearing waterways may have debris such as pine needles or moss that can
enter the cooling system and create a blockage against this screen. Failure to
perform this function can result in serious overheating of the engine. Damage
to the engine caused by overheating is not covered by warranty! Always pay
attention to your temperature gauge, even if you are carefully performing
this check. Blockage of the transmission cooler or a faulty raw water impeller
are too-frequent causes of overheating. Water in the transmission may void
the warranty!

CHECK THE COOLANT LEVEL
This procedure applies only to boats equipped with the fresh water cooling
system or closed system. Because this process should be completed while the
engine is cool and cannot cause burns to your skin, we recommend you do this
before starting your boat.
Step 1: Ensure the engine is OFF and the engine safety switch disconnected. Be
sure the throttle/shift control lever is in neutral. Open the engine compartment
and locate the closed cooling system tank adjacent to the engine.
Step 2: Remove the cap and check the level, which should be 2/3 full. If the level is below
that, add coolant (only ethylene glycol or propylene glycol) in the appropriate mixture with
distilled water. DO NOT overfill the tank. DO NOT mix anti-freeze types. See the Storage and
Winterization section of this manual for additional details regarding coolants.
