Pro Boat PRB2550 - Manual (Page 15)

15
The Pro Boat ™ Miss LLumar should provide many
hours of exciting high-speed racing fun with just
minor maintenance. Preventative maintenance is
very important. Taking the time to make sure all
of the screws and bolts are properly secured before
each run and after each operation and regularly
lubricating the flex cable will prevent
many problems.
Replacement parts are available from Pro Boat. See
the back of this manual for specific descriptions and
item numbers.
Items Required
2mm hex wrench
Waterproof grease
Threadlocking compound
It is vitally important to properly lubricate the flex
drive shaft and the propeller shaft with heavy cable
grease every 5–10 hours of operation. You will
also find that it will eventually become necessary
to replace the Teflon liner sleeve of the drive shaft.
At some point, it may also become necessary to
replace the drive shaft (flex cable) as well.

The hull of the Miss LLumar 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 Miss LLumar 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.
