SCHEDULED MAINTENANCE

Before Each Use

Prior to Starting the Engine

Review the Safety Checks and Services section of this Owner’s
Manual. There are important functions that must be followed before,
during and after every outing. The Safety Checks and Services
section notes that all drain plugs must be reinstalled prior to
operating the boat. This is critical to prevent taking on water.

Inspect Seacock Strainer

Because a clogged seacock strainer puts undue strain on the
engine(s), the strainer should be checked prior to starting the boat.
The seacock strainer is standard on all boats.

BEFORE EACH USE

Before Starting the Engine

Review the engine manual before each outing to determine the
drive train requirements that need to be followed prior to each use.
Review the Safety Checks and Services section of this Owner’s

Manual. There are important functions that must be followed before,

during and after every outing:

• Inspect the raw water intake water strainer for blockage. If there

is blockage, also check the transmission cooler (where equipped).

• Check and clean as necessary the seacock strainer.
• Check the cooling system level. See the engine owner’s manual

for details.

•  Inspect the battery connections and hold-downs.
•  Inspect the drive train for loose or missing hardware.
•  Inspect the throttle and shift cables for kinks, wear and interfer-

ence with other components.

•  Inspect the propeller shaft log for excessive water entry.
•  Inspect the fuel system lines and connections for leaks.
•  Check for water leaks or excessive exhaust odor.
•  As you start the engine, check that the voltage reading registers

a fully charged battery.

Step 1

Open and lift the cover.

Step 2

Remove the filter and inspect for debris. Manually clean the strainer.

Step 3

Check for debris and remove anything found inside the sea strainer.

Step 4

Return the lid and tighten in place.

AFTER EACH USE

Refer to the Cleaning the Boat and Corrosion Prevention sections
of this Owner’s Manual for guidance on a thorough approach to
maintenance. Also pay attention to the information provided re-
garding the maintenance of Garapa Gold platforms and accessories
because the wood requires periodic maintenance as well.

Boats equipped with an optional flushing system for use in salt
water or brackish water should operate the flushing system.
