 2023 OWNER’S MANUAL 
 
Immediately stop using the tower if it appears to be unsteady, 
insecure, or shows signs of gel coat cracking or other stress 
near the tower legs. Continuing to use the tower under these 
conditions could result in serious injury or even death.  
An authorized MasterCraft dealer must determine if the damage 
can be repaired. If the damage is the result of misuse of the 
product, such damage will not be covered under the  
warranty policy.
Troubleshooting
In rare cases, the Z6 pull-pin locking mechanism may have 
trouble engaging. This is a result of misalignment and may lead 
to scarring. If the locking mechanism on your Z6 does not engage 
properly, take it to an authorized MasterCraft dealer  
for inspection. 
If the Z8/Z10 tower does not respond to the switch, verify that the 
circuit has not tripped at the cylinder/pump. If it has not tripped at 
the cylinder/pump, examine the breaker board. (See the chapter 
“Basic Electrical Components” for information on breakers.) If the 
tower is still unresponsive after toggling the breaker, you should 
take the boat to an authorized MasterCraft dealer. 
Although Z towers are sturdy, well-designed equipment, you 
should know what to do in the unlikely event that a tower causes 
damage or exhibits signs of insecurity. If there is evidence of 
tower-induced damage to the deck (such as gel coat cracking) or 
insecurity (such as unsteadiness), stop using the tower and take 
it to an authorized MasterCraft dealer for closer inspection. The 
dealer will be able to diagnose repairs. If the damages appear to 
have been inflicted by the owner’s actions, warranty may not cover 
the repairs. 
If you have any questions regarding the hydraulics used in the 
Z8 and Z10 towers, contact an authorized MasterCraft dealer. 
The dealer can provide information from the OEM manufacturer 
regarding installation instructions, system diagrams, part 
numbers for hoses or fittings, thread sealant, hydraulic fluid, pump 
filling processes, test procedures, operating pressure, alternate 
means of operation, maintenance, and/or troubleshooting.
