The Pro Boat™ ThunderCat 31 should provide
many hours of exciting high-speed racing fun with
just minor maintenance. Preventative maintenance
is very important. Taking the time to ensure that
all the set screws and bolts are tight before each
operation of the boat will prevent many problems.
Before operating ThunderCat 31
Check that all screws and hardware are securely in
place. This is very important, as the manifold screws
will occasionally vibrate loose during the first initial
runs.
Check the propeller for damage in the form of
chipping or cracking. If you find any damage,
replace the propeller, as the damage will effect
the performance of the boat and could also cause
safety concerns.

Section 12: Maintenance
When refueling, always wipe away any excess fuel
that may have spilled into or on the boat.
After operating the ThunderCat 31
Wipe off any exhaust residue from the boat. If
you operate the ThunderCat 31 in salt water, it is
suggested that you thoroughly rinse the deck, hull,
and all the metal hardware with fresh water, then
dry them with a clean towel. After cleaning, coat all
metal parts with a silicone spray lubricant. This will
help to prevent corrosion.
Ensure that the radio box and equipment
inside is dry.
