The plate weighs 35kg and is powered
by an electric actuator. It uses a worm screw to move the top plate
in and out.
Usually the switch would be mounted on the dashboard of the boat,
and is similar to a trim switch. It has 3 positions: forward, backward
and central “off” position which is the default if you
exert no pressure on the switch. This locks the plate wherever it
is when you take your finger off.
The Power Set Back is a horizontally adjustable plate that allows
you to move your outboard motor to and from the boat transom. Powered
with an actuator permits this adjustability to take place whilst
driving the boat. This will enable you to improve and maximise boat
performance in all water conditions.
Calm water for long, heavy boats.
In a majority of circumstances, boats are too long and, or heavy
in the nose for the power of the motor. In these circumstances boats
cannot achieve maximum trim (the power of the motor affects the
lift. If the angle of the boat against the water is applied with
more force it creates more lift).
Two factors improve trim capabilities when moving the engine back.
By moving the heavy motor further back, you are moving the balance
point back, making the nose of the boat easier to lift. In addition,
moving the engine back gives the power of the propeller thrust better
leverage against the boat, improving trim capabilities immensely.
With the combination of the easier lifting nose and stronger trimming
abilities, the boat can reduce surface area on the water. Consequently,
top speed of the boat will dramatically increase.
Calm water for short, light boats.
To get maximum speed from a boat, minimum surface area and minimum
resistance against the water is needed. To do this, typically the
boat is trimmed upwards allowing the angle of the boat against the
water to create lift. This is how minimum surface area on the water
The angle of the boat against the water creates lift, but it also
creates resistance against the water. By moving the heavy motor
further back, you are moving the balance point back, making the
nose of the boat easier to lift. With the nose being easier to lift,
the boat can achieve the minimum surface area with less of an angle
against the water. With less of an angle against the water resistance
is reduced, thus better high speed performance.
Running the boat with less of an angle against the water, (less
trim) improves high speed boat handling across side wash, chop and
When setting the boat up for rough water, the goal is to keep the
nose heavy or harder to lift so the waves don’t throw the
boat nose in the air.
Having the motor set away from the transom, like the industry standard
of a 6 inch setback, will be a disadvantage in rough conditions.
The optimum setup is to have the motor against the transom. This
moves the balance point forward, making the nose harder to be lifted
by the big waves it needs to negotiate. This set up also decreases
load on the transom through rough conditions.
The Power set back impacts steering behaviour. In comparison, it
would be like adjusting the wheel base of a car. Lengthening the
wheel base will improve stability and precision of a car at high
speed. Shortening the wheel base will allow tighter turning circles
and more response.
Setting the motor against the transom will increase response of
steering, steering response is vital in rough water conditions.
Setting the motor back decreases steering response but uses leverage
to increase steering strength and more noticeably, precision. This
assists high speed handling. However at low speeds, this set up
is not optimum.
The adjustment in steering behaviour that the adjustable setback
provides is the only steering adjustment on the boating market.
This capability is a proportional side benefit.
The Power set back can be adjusted to suit the propeller in use.
Moving the motor back gives the propeller more water around it to
grip. Moving the motor against the transom gives the propeller less
water around it and allows it to slip. Adjustments can be made to
suit requirements. Moving the engine against the transom assists
with keeping the nose level through take off.
Move the motor against the transom to decrease transom load whilst
The Power set back will give the flexibility to adjust your boat
setup to suit all conditions by moving the motor horizontally to
the boat transom. Powered with an actuator permits this adjustability
to take place whilst driving the boat. Applying the a Power setback
correctly provides significant advantage against competitors in
all race situations.
