Inspect the Exhaust Flaps for Damage
Step 1: Ensure the engine is OFF and disconnect the engine safety starting switch. Be sure that the
throttle/shift control lever is in neutral.
Step 2: Inspect the exhaust flap hinge for signs of deterioration. Replace the flap if necessary.
Lubricate the Steering System
Because this process should be completed while all movable components of the drive train are NOT in mo-
tion, MasterCraft recommends this be done while the boat is out of the water.
Step 1: Ensure the engine is OFF and disconnect the engine safety starting switch. Be sure that
the throttle/shift control lever is in neutral. e engine must be cool.
Step 2: Remove the access panel in the rear trunk compartment in direct drive boats. In V-drive
engines the steering is located in the engine compartment, beneath the engine.
Step 3: Turn the steering wheel so that the maximum amount of steering cable is seen.
Step 4: Use solvent to clean old lubricant from the cable end, pivot and rudder shaft.
Step 5: Spread a generous amount of white lithium grease over the cable end. Work the
steering wheel back and forth and re-apply grease if necessary.
Step 6: Using the flexible end of a grease gun, give two (2) full shots of white lithium grease
to the two (2) grease fittings: one on the rudder shaft, and one on the pivot. Clean up
any old grease purged from the areas.
Step 7: Rotate the steering wheel back and forth several times to work the lubricant in.
Step 8: Re-install the access panel.
Lubricate the Shift and Throttle System
Because this process should be completed while all movable components of the drive train are NOT in motion, Mas-
terCraft recommends this be done while the boat is out of the water.
Step 1: Ensure the engine is OFF and disconnect the engine safety starting switch. Be sure that
the throttle/shift control lever is in neutral. e engine must be cool.
Step 2: Open the engine box and locate the shift and throttle cable ends.
Step 3: Shift to full-throttle-forward.
Step 4: Lubricate the cable ends and connections with a coating of waterproof marine multi-
purpose grease.
Step 5: Lubricate the pivots and linkages with a light grease.
Step 6: Shift the control lever from full-throttle-forward to full-throttle-reverse several times to
work the lubricant in.
Check the Ballast Pump Impeller
is applies only to boats equipped with some type of ballast system. e number of ballast pumps varies from system
to system. Authorized MasterCraft dealers can provide guidance to locate any and all pumps.
Step 1: Remove two (2) of the cover screws and retain the screws for the reinstallation process.
Swing the cover out of the way to allow access to the impeller location.
Step 2: Using needle-nose pliers, pull the old impeller out of the casing.
Step 3: Install a new impeller. (It is intentionally larger than the case. While gently
squeezing it in, ensure that the paddle wheels angle in the same direction—
counterclockwise—all the way around.)
Step 4: Slide the plate back into place. No silicone is necessary. Due to the built-in gasket,
tightening the screws should prevent leakage.
Inspect the Complete Fuel System for Leakage
Although the boat engine is similar to an automobile engine, the engine compartment differs substantially.
e underside of an automobile engine compartment is totally open to the atmosphere. is allows complete
