MasterCraft 2009 MariStar X-Series Manuel D’Utilisation

   (On Ballast-equipped Models Only)

On boat models equipped with a ballast 

system, a separate three-position switch 

will allow for the filling or emptying of the 

ballast tanks and/or bags. Be aware that 

Check engine specifications for related 

engine idle speed, which may be too low 

for the empty/fill operation to be properly 

accomplished; it is likely that the boat will 

need to be in motion during the filling and 

emptying of the ballast system. Failure to increase engine RPM 

to the required level may result in malfunction or permanent 

damage to the ballast pumps that force the water through the 

system. Such damage is not covered under your warranty. The 

ballast controls vary in location by model, and the operator 

should determine exact location prior to use. The three-position 

switches are clearly marked; FILL, OFF (in center), and EMPTY.

The bilge pumps on all V-drive models will 

be in the automatic mode when the igni-

tion key is turned ON. Some models may 

have two (2) switches, one for the forward bilge and one for the 

aft. In these instances, the switches will be marked. The manual 

and automatic bilge discharge system is never completely off. 

When in the automatic (default) position, a sensor alerts the 

system to discharge water from the bilge area. Boat operators 

are advised to leave the switch in the automatic position, unless 

there appears to be excess water in the bilge. In that event, the 

bilge pump can be manually activated by turning the bilge pump 

switch to the manual ON position. Return the switch to the au-

tomatic position when finished emptying the bilge. Leaving the 

switch in manual mode can result in damage to the pump and 

may not be covered by warranty! 

    (All Models)

A two-position rocker switch activates the 

engine box ventilation blower. Push the top 

half of the switch to turn the blower ON.

All major boat circuits are pro-

tected from shorting and overload 

by re-settable circuit breakers. If a 

problem develops with one of the 

following circuits, switch OFF the 

circuit and wait for approximately 

one (1) minute. Then fully push 

the appropriate breaker button and 

switch ON the circuit. If the circuit 

continues to trip, there is a problem 

somewhere that must be attended to immediately. See your au-

thorized MasterCraft service department to resolve this matter.

The location of the main circuit breaker board is under the dash 

panel. In some models, there is an additional breaker panel to 

assist with the accessory load, and where equipped is located 

near the battery box. There may also be a waterproof fuse for 

the stereo amplifier, where equipped. If the boat’s accessories are 

malfunctioning, check and then re-set breakers as necessary.

The engines are also equipped with breaker systems. The main 

35A circuit breaker protects the engine electrical system and 

components from overload. If the engine will not turn over with 

the battery switch in the ON position, locate the red breaker re-

set button (labeled “35”) in the engine. There will be an audible 

click. Try again to start the engine. If the breaker trips again, the 

engine requires attention. Immediately take your boat to your 

authorized MasterCraft service department.

In addition to the 35A circuit breaker, the engines are equipped 

with additional component overload protection, including a 15A 

ATO fuse for the fuel pump, a 15A ATO fuse for the injectors 

and a 15A ATO fuse for the ECM unit.

If you suspect that any of these fuses may not be operating as 

designed, you should take your boat to your authorized Master-

Craft service department for inspection and repair.

If during maintenance or inspection it becomes necessary 

to remove or re-position any of the engine’s wiring or wire
