Owner’s Manual

Auto Bailers

Your boat is equipped with two auto bailers. Each auto 

bailer works as a mechanical one-way valve. 
Inside the auto bailer is a ball bearing and a rubber seal. 

The ball bearing is free to move when the bailer is not in 

contact with water, allowing water to exit the hull. 
Once submerged, the pressure from the water presses 

the ball bearing against the rubber seal, preventing water 

from entering the hull.

1.  Keep the inside of the hull clean and free of debris to 

ensure the auto bailers will work properly.

2.  When you apply throttle and the boat is on plane, the 

auto bailers are out of the water. The boat’s forward 

momentum drives the ball bearing back, opening the 

valve and allowing the water inside the the boat to 

exit the hull.

3.  Once you remove the boat from from the water, tip 

the nose of the boat upwards and water in the hull 

will run from the auto bailers.

Testing and Servicing

Under normal use, it is not necessary to service the 

auto bailers often because there are no wearable parts. 

However, if you run your boat in salt water or in water 

with high chemical content, it may be necessary to 

inspect the components inside the auto bailers for wear. 

PRB286043 has the necessary parts to replace worn 

parts or replace the auto bailers completely.

1.  Carefully unscrew the end of the auto bailer, taking 

care not to drop the aluminum ball bearing inside the 

auto bailer as you remove the cover. 

2.  Remove the ball bearing and inspect it for pitting. If 

the ball bearing doesn’t look worn or pitted, you can 

reuse it.

3.  Carefully remove the O-ring from inside the bailer 

housing. Use tweezers to remove the O-ring if you 

cannot reach it otherwise. 

Do not use sharp tools  

to remove the O-ring or you may damage it or 
tear it.

4.  Inspect the O-ring for wear or tears. Replace it as 

necessary.

5.  If the parts are not worn, reinstall them in reverse 

order.

NOTICE: 

 Do not apply grease to the auto bailer O-ring. 

Doing so could prevent the ball bearing from moving 

freely inside the bailer housing.

NOTICE: 

 Do not use thread locking fluid on the auto 

bailer housing cover. Doing so will prevent you from  

later servicing the bailer and could damage the bailer.

Replacement

1.  Use a soldering iron to apply heat to the auto bailer. 

Place the soldering iron on the middle ring of the auto 

bailer while holding the bailer with a pair of pliers.

2.  As the bailer heats up, lightly apply back and forth 

lateral pressure to the bailer. The bind between the 

bailer and the epoxy will weaken. 

CAUTION:

  Applying too much force or too 

much heat can damage the hull. 

3.  Once the auto bailer is free, set it aside to cool and 

dispose of it accordingly. 

4.  Disassemble your new auto bailer and set the ball 

bearing and O-ring in a safe location. Use a nail file 

or medium emery cloth to remove the smooth finish 

around the neck of the bailer. The neck of the bailer 

inserts into the hull. 

5.  Apply a 

minimal

 amount of medium CA (DYNK0030) 

around the neck of the auto bailer. 

6.  Once the bailer has been inserted and glued, we 

recommend adding CA to the bailer from inside the 

hull. Take care not to run CA into the bailer housing. 

If it runs into the bailer housing, use a cotton swab 

lightly soaked in acetone to remove excess glue.

7.  Allow the CA to dry overnight. Once it is dry, 

assemble the bailer by installing the O-ring, ball 

bearing, and bailer cap.
