Pro Boat PRB2850 - Manual (Page 9)

1 1
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 set screws 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.
m 1. Loosen the two 1.5mm setscrews on the
brass ferrule located in front of the propeller
strut and remove the propeller shaft assembly
from the rear. Note that there is a nylon bushing
located on either end of the propeller strut.
m 2. Remove the lower propeller strut mounting
bolt and loosen the top bolt. Rotate the
propeller strut upwards to access the flex shaft.
m 3. Slide the flex shaft out of the boat.
m 4. Lubricate the flex shaft with flex shaft grease
(see your local hobby shop). Reinstall in reverse
order. Be sure to reinstall the nylon washers in
front and behind the propeller strut.
