ENGINE MAINTENANCE:
Ways To Ensure A Long Life For Your Engine.
• Keep your engine clean. Dirt will act as insulation on an
engine and prevent it from shedding heat easily.
• Do not over-lean your engine.
• Do not run your engine without a propeller.
• Do not overheat the engine. This goes along with keeping
it clean and not over-leaning the engine.
• Avoid using old fuel in the engine. Always run all of the
fuel out of the engine. After running for the day, use after-
run oil and work it into the engine by pulling the pull-
starter 2-3 times.
• Store your engine someplace where it will not be
subjected to extreme temperature changes.
• Before transporting your model, remove all of the gasoline
from the tank and lines.
• If you are not planning to run your engine for more than a
month, drain the fuel tank and remove any fuel from inside
the carburetor. Do this by running the engine at idle until it
quits by running out of fuel. Keeping gasoline inside the
carburetor over an extended period of time will damage the
diaphragm valve and clog passages inside the carburetor.
RADIO BOX MAINTENANCE
• Line the forward interior of the radio box with paper towel
prior to running to absorb moisture.
• Place the receiver in a rubber balloon to provide added
protection from moisture.
• Use a water-resistant tape to seal the radio box lid to the
radio box.
• When finished running, open the radio box and soak up any
moisture that may have made its way into the compartment.
• Should moisture gain access to the radio box, all
connections should be dried thoroughly. Hobbico “Duster”
Compressed Air (HCAR5500) will provide a blast of air
capable of blowing moisture out of connectors.
HULL MAINTENANCE
• After running, the exterior of the hull should be cleaned.
Common household cleaners can be utilized for cleaning.
Areas exposed to fuel/engine exhaust residue should be
thoroughly cleaned. Agents in the fuel/exhaust residue can
attack the finish if allowed to remain on the surface over time.
As an initial starting point, try running the V24 with a neutral
propeller thrust angle (See Figures 1-3 above). This can be
checked by placing a straight edge along the bottom of the
hull and checking its relation to the prop shaft.
Neutral Propeller Thrust: Provides thrust without letting the
thrust affect the ride attitude of the hull (the bow’s tendency
to ride up or down).
Positive Propeller Thrust: Causes a “bow upward” ride
attitude. A “bow upward” ride attitude will increase speed but
as it does, handling becomes more sensitive.
Negative Propeller Thrust: Causes the hull to ride “stuck
down” (flat on the water). This reduces speed and may
cause the boat to submerge in a turn.
Be sure to retighten all the screws upon establishing the
desired thrust angle.
