The hull of the Blackjack 55 is finished using the highest quality
paints and the most advanced painting methods available. The
base coat/clear cote technique delivers an amazing shine that is
as durable as it is beautiful. To keep your Blackjack 55 looking
new, you should apply a wax coating as used on automotive
finishes to prevent oxidation and to further protect against
damage caused by fuel and other harmful chemicals.

The Pro Boat Blackjack 55 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 setscrews and bolts are tight before each
operation of the boat will prevent many problems.
Before operating Blackjack 55:
Check that all screws and hardware are securely in place. This
is very important, as the manifold screws will occasionally
vibrate loose during the 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 affect the performance of the boat and could also
cause safety concerns.
When refueling, always wipe away any excess fuel that may
have spilled into or on the boat.
After operating the Blackjack 55:
Wipe off any exhaust residue from the boat. If you operate
the Blackjack 55 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.
