E. Surge Brakes
Surge brakes are available on certain model trailers
manufactured by Four Winns. Surge brakes operate
automatically when the tow vehicle’s brakes are
applied. When the tow vehicle slows down or stops,
the forward momentum or “surge” of the trailer against
the hitch ball applies pressure to a master cylinder
in the trailer coupler. The master cylinder supplies
hydraulic pressure through the hydraulic system which
activates the trailer’s brakes. See Figures S5 and S6.
Please refer to the manufacturer’s literature included
in your owner’s packet for further details regarding
operation and maintenance.
Figure S5: Brake Actuator & Coupling Assembly
For boat models with the Surge Brake Actuator and
Coupling Assembly shown in Figure S7, place the
coupler latch in the open position to unlock the coupler.
Push down on the coupler latch to lock the trailer to the
ball hitch. Push coupler latch back until the latch
engages and is properly seated. The safety pin, pro-
vided with the trailer, or a padlock must be inserted
completely in the coupler latch hole. This ensures
the coupler’s latch remains in the locked position during
towing of the trailer. Refer to Section S-3 Operation for
additional information on couplers and hitching to the
tow vehicle.
NOTICE
Anti-sway devices as used on recreational
vehicles (RV’s) are not applicable to surge
brake systems and should not be used on

trailers.
DO NOT use a trailer hitch with moving parts.
The brakes could activate when traveling
downhill. Always use a fixed hitch.
If the brakes are wet from loading, travel at a slow
speed and apply the brakes on your towing vehicle
several times to “dry” out the trailer brakes.
Safety Pin
4. When raising or lowering the jack, prevent the
caster from rotating while cranking. Make sure the
jack is planted on a firm and level surface before
unhitching the trailer.
To prevent personal injury or damage
to the boat and trailer, observe the following:
• NEVER pull on the lock pin when any
trailer weight is on the trailer jack.
• DO NOT move the trailer when resting
on the swivel jack. Use towing vehicle
to move the boat and trailer.
• Keep body and feet clear of trailer
tongue when raising or lowering jack.
Always remember to swivel jack to the horizontal
position before towing the trailer. Damage to the
caster and jack may result.
The swivel jack provided on the Four Winns
®
trailer
can be removed from the trailer to allow for mainte-
nance or repairs. Follow the manufacturer’s recom-
mendations provided in the owner’s packet.
D. Coupling Assembly
To unlock the coupler, pull the locking trigger upward
with your index finger and lift the locking lever. To
lock, push the locking lever down. See Figure S5.
