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
disconnected. 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 sys-
tem 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 start-
ing 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 re-
garding coolants.
