Handling Characteristics; Driving At A High Speed - buster Magnum Pro Betriebsanleitung

and the boat is in motion, it is recommended that both batteries be kept in the ON
position. The charging relay ensures that both batteries charge when the engine
is on. If you would like to use the boat's electrical system with the engine switched
off, disconnect the primary battery from the system by putting the main switch in
the OFF position. This will enable the primary battery to remain charged even if
the secondary battery is entirely discharged while the boat is stationary. The wiring
diagram for the double-battery system is shown in Appendix 4.
When you are purchasing new batteries or upgrading old ones, it is recommended
that the primary battery be a starter battery that is able to produce large currents.
The second battery should be a deep cycle battery with high energy density, such
as an AGM, gel or lithium-ion battery. If you are using a special type of battery, take
note of any specific requirements in terms of connections, charge regulators, and
protection from water.

Driving at a high speed

Do not operate the boat if the actual engine power exceeds the power indicated on
the builder's plate.
If the motor has an electro-hydraulic power trim, the basic trim angle adjustments
are as follows:
• To plane the boat, the trim should be adjusted all the way down (negative
setting: "bow down").
• When the boat is planing in low waves, the trim should be raised until the
boat starts to porpoise, the propeller loses grip or the engine reaches the
upper limit of the normal adjustment range. When this happens, lower the
bow slightly until the ride is stable. The log (speed indicator) can be used to
optimise the trim angle.
• When the boat is riding into waves, the bow should be lowered until the ride
becomes smooth. When driving with a tailwind or driving into very high waves
the bow should be raised slightly to avoid ploughing through the waves.
• Do not drive the boat at a high speed with a fully negative trim angle
(bow down) as this may cause the boat to roll from side to side and make
steering unstable.
Please also consult the engine manual.
Outboard engines are usually designed to be mounted at a height that aligns the
engine's cavitations plate with the boat's keel.
WARNING! Be careful when you adjust the trim angle at high speed as
this can dramatically affect the boat's handling. Do not angle
the bow too far down as this can cause the boat to handle
erratically.
