The hull of the Formula Hydro 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 Formula Hydro looking new, you should apply a wax coating to the top of
the hull as used on automotive finishes to prevent oxidation and to further protect against damage caused
by fuel and other harmful chemicals. Also, keep boat out of direct sunlight for extended periods of time
to prevent fading.
The Pro Boat
Formula Hydro 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.

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.
