Materials

The Outboard Power Setback is made from marine grade aluminium. As such it is light weight, strong and rustproof.

 

Design
The design consists of 2 plates – one fixed plate that is bolted to the back of the boat and has rails that extend backwards, and another plate that fits over this and slides along two rails. The motor is bolted onto this second plate so that it is free to be moved backwards and forwards.

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.

 

Technical

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 is achieved.

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 cornering.

 

Rough water

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.


Steering

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.


Take off

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.


Travel

Move the motor against the transom to decrease transom load whilst travelling.

 

Conclusion

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.
