CLEAN THE ENGINE FLAME ARRES-
TOR
MasterCraft recommends that you have the flame
arrestor inspected and cleaned by your dealer immedi-
ately prior to starting the boating season. This procedure
is extremely important and should be performed at least
once a year.
There may be instances in which you need to check
this yourself. If you have had evidence of material collect-
ing inside the flame arrestor in the past, you should check
yours more often than annually, particularly after the boat
has been sitting for an extended period of time. The
flame arrestor serves as a trap for airborne materials
that might otherwise enter the engine and cause
damage. However, if your boat sits for a while, small
creatures may crawl inside and build a nest.
Be very careful while removing and while the flame
arrestor is off the engine that absolutely nothing foreign
enters the engine through the area normally covered by
the flame arrestor. Any materials entering can cause
damage to your engine and will void your warranty.
Because this process should be completed while the
engine is cool and cannot burn 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. The engine must
be cool.
Step 2: Carefully remove the flame arrestor from
the back of the engine using a screw driver on the
clamp screw.
Step 3: Tap the element to dislodge any large embed-
ded dirt and then gently brush with a soft bristle brush.
Note: Do not use gasoline, steam, caustic cleaning
solution, strong detergent, high-pressure car wash or
parts cleaning solvents. Any of these can harm the
cotton filter media, as well as shrink and harden the
rubber end caps.
Step 4: Either spray on K&N air filter cleaner or allow the
air filter to soak in a pan filled with air filter cleaner. Allow
the cleaner to work for approximately 10 minutes.
Step 5: Rinse off the filter with low-pressure water. Tap
water is okay. Always flush from the clean side to the
dirty side. This removes the dirt and does not drive it
into the filter.
Step 6: Always dry naturally. After rinsing, shake off all
excess water and let the element dry naturally.
