Section 14: Clutch; Section 15: Hull Care; Section 16: Maintenance - ProBoat Formula Owner's Manual

Section 14: Clutch

The centrifugal clutch automatically engages when
the engine rpm is increased. Be sure the idle speed
adjustment is set low enough so that the propeller
does not rotate at idle.

Section 15: Hull Care

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.
Periodically disassemble the clutch and clean debris
from the clutch shoes and the inner clutch bell with
DYN5505 Dynamite ® Nitro Force.

Section 16: Maintenance

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.
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.
Simply follow the instructions below to properly
lubricate your drive shaft.
q 1. Carefully note how the entire drive shaft is
installed. This is pivotal in order to properly
reassemble the drive shaft after you have
finished lubricating it.
q 2. Loosen and remove the two 2.0mm set
screws that secure the propeller shaft to the
brass ferrule. Remove the prop drive dog and
nylon washer.
q 3. Remove the drive shaft flex cable. Replace the
Teflon liner as needed.
q 4. Lubricate the entire flex cable with waterproof
grease (PRB0100) as shown and then reinstall
the flex cable back through the liner and stuffing
box and into the clutch.
q 5. Reassemble in reverse order. Make sure the
setscrews are tightened down on the flat spots
of the prop shaft. Also be certain to place a
drop of threadlock on each setscrew before
retightening them.
