Uncoupling
When uncoupling the trailer, place blocks at the front and rear of 
the trailer tires to ensure that the trailer does not roll away when 
the coupling is released.  
 
Unbalanced Load
An unbalanced load may cause the tongue to suddenly rotate 
upward; therefore, before uncoupling, place jack stands under the 
rear of the trailer.
Dicult Towing
If a trailer seems hard to tow or sways to one side, a brake rotor 
may not be rotating freely. If this appears to be the problem, 
immediately contact your authorized MasterCraft dealer for 
assistance. Ignoring this symptom could result in brake failure.
Check Trailer Jack and Lug Wrench
The trailer jack and lug wrench that came with the tow vehicle may 
also work on the trailer, but don’t count on it, check it to be sure 
before you need it.
Road Trip Kit
Make up a special road trip kit and carry it with you on all trips. The 
kit should include a spare wheel and tire, lug wrench, wheel chocks, 
bearing grease, spare strap for tie-downs and winch, extra lights, 
wheel bearings and road flares.
Insurance
Some insurance policies do not provide coverage when towing a 
trailer. Check the policy or call the insurance agent to be certain 
that you have appropriate insurance coverage in place.
 
 
 
The total weight of the boat, engine, fuel, water and gear must not 
exceed the trailer’s maximum load-carrying capacity. Overloading 
can cause instability and loss of control while towing, which may 
result in death, serious injury or property damage.
