Step 5: If you are uncertain about the condition of the impeller,
remove it and inspect. When installing or re-installing one, you will
find it is a tight fit. This ensures proper operation. The use of soap or
Vaseline will help with installation. You will note that proper place-
ment on the gear results in a squeeze on the arms. This is the
correct installation.
Step 6: Place a gasket between the housing and the cover after
ensuring that the surfaces are smooth and clean; then re-install the
screws in place. Do not over-tighten the brass screws. This can
cause them to break.
INSPECT THE PROPELLER SHAFT LOG FOR EXCESSIVE WATER ENTRY
This inspection requires the operation of the engine with the engine compartment open; thereby creating a potentially
dangerous situation. Therefore, this inspection should be performed by your authorized MasterCraft dealer. . Whenever this
inspection is performed, utmost care must be exercised to avoid personal injury or death.This inspection must be per-
formed with the boat in the water. Your MasterCraft dealer will perform the following steps in conducting the inspection:
FOR THE PROSTAR 190, 197, 209, X-7 AND X-9 MODELS:
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.
Step 2: Begin with the boat in the water. Open the engine box and check for leakage while the engine is OFF. No leakage is
permissible while the engine is OFF. If any is apparent, refer to the Check Propeller Shaft Coupling Alignment section in the
Annual maintenance section.
The engine box serves as a machinery guard. The engine must be OFF
whenever the box is open. Clothing or body parts can get caught in
moving parts, causing serious injury or death. Keep away from moving parts!
Step 3: This portion of the inspection requires the operation of the engine with the engine compartment open and
should be performed by your MasterCraft dealer. Your dealer will start the engine with the engine compartment open to
inspect the shaft log for leakage. Ten-to-fifteen drops of water per minute is normal. If the water entry is excessive, however,
then the packing gland must be adjusted. To adjust:
• Turn the engine OFF.
• Loosen the packing gland nut.
• Hand-tighten the packing gland nut and re-tighten the lock nut.
• Operate the boat again and check for the proper adjustment. If
the water leakage continues, the shaft log may need to be re-
packed. Check the alignment also. Contact your MasterCraft dealer
for assistance as needed.
FOR THE X-1, X-10, X-STAR
AND ALL MARISTAR MODELS:
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.
Step 2: Begin with the boat in the water. Open the engine box
and check for leakage while the engine is OFF. No leakage is
permissible while the engine is OFF. If any is apparent, refer to the
Check Propeller Shaft Coupling Alignment section in the Annual
maintenance section.
