 2023 OWNER’S MANUAL 
2.  Open the engine compartment and visually check as much of the 
fuel system from the tank to the engine as you can see. On some 
models this is will be a limited area. If the odor of gasoline is strong 
or if you see visual evidence of fuel outside the system, cease 
all operations and take the boat immediately to an authorized 
MasterCraft dealer’s service department to determine the 
source of the leak. The leak must be repaired before the engine is 
restarted. Because the lines on late model MasterCraft boats are 
pressurized, they can be disconnected and/or removed ONLY by 
using specialized tools.
 
 
Gasoline is highly flammable and its vapors may ignite, resulting in 
fire or explosion. Be sure to keep all sparks and flames away from 
the area while inspecting the boat’s fuel system. 
 
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 death or serious injury. Keep 
away from moving parts!
Fuel leakage can lead to a build-up of potentially explosive fumes 
within the engine compartment. 
DO NOT IGNORE OR OVERLOOK THIS INSPECTION AND REPAIR  
AS NECESSARY!
INSPECT THE FUEL SYSTEM  
FOR LEAKS
This function should be performed prior to starting the engine; and 
then again after about three (3)-to-five (5) minutes to determine 
whether any leaks are apparent.
1.  Ensure the engine is OFF, the engine safety starting switch is 
disconnected and the throttle/shift control lever is in neutral.
