Product Evaluation: Livorsi Marine Wireless Trim System
Article and Photos by Greg Terzian
Page 1 2

Livorsi's wireless trim system offers a clean installation with no wires, bulky helm-mounted components, and integration with almost any steering wheel.

The importance of trimming the engine or drive unit in a performance boat is well-known. The trim angle affects the overall running attitude of the boat, and in a high performance application, proper trimming is crucial for maximum performance and safety.

For the above reasons, high performance boats generally have the trim controls situated in a location where it is most accessible, without the driver having to look for them. Since performance-minded boaters are always adjusting the drive unit trim angle, a common location for mounting the trim switches has been on the steering wheel itself. This purpose was two-fold – first, the driver could keep both hands on the wheel at the same time while adjusting the trim, and second, the driver could keep their eyes where they belong – on the water moving quickly below them. The problem with this system is the coil of wire that connects the actuators on the steering wheel can become tangled easily. On a boat equipped with hydraulic steering, this was not even an option, since hydraulic steering systems are not limited in their wheel travel.

 

The wireless transmitter resides neatly in the hub of the steering wheel. A single coin cell delivers power for one year of use.

Other common solutions include the ‘turn signal’ style trim actuators, which resemble the turn signal branch on an automotive steering column. This worked well for tunnel boats with hydraulic steering, but many v-bottom owners could not adjust to the awkward feeling of this system since the V-bottom requires much more steering feedback from the user. Cordless helm systems have gained wide acceptance among users as well, incorporating the actuator electronics into the helm and steering wheel as a complete system. The main drawback of this system is that it required a steering wheel and helm actuator to be used as a unit.

Livorsi Marine brings a new product into this category that allows for more flexibility and customization options, as well as the ability to be incorporated into almost any steering wheel. Hydraulic steering systems benefit from this system the most, since there is no real on-center location for the wheel, and switch cords could quickly become a nightmare - or even a hazard.

Livorsi’s Wireless Trim-In-Wheel system uses a radio transmitter that is installed into the steering wheel hub and a receiver to control trim, engine height, K-planes, or any other device you choose. What sets the Livorsi system apart is its expandability, offering the user wireless control for a variety of systems on the boat.

 

Color coded trim buttons are mounted within easy reach, yet they are not obstructive in any way. The pair exists on both sides of the steering wheel.

The system consists of a small transmitter that is concealed in the hub if the steering wheel and a receiver that switches the connected devices. The transmitter powered by a small 3-volt lithium-ion battery that’s good for one year of use before replacement is required. High quality, positive feedback switches are connected to the transmitter, which can accept multiple switch connections to operate up to eight different functions (up and down commands each count as a respective function).

The receiver is housed in a plastic box not much larger than a deck of cards, which is powered by the 12-volt power source on the boat.  Utilizing reliable NEC/Tokin relays (4) to deliver power, they are rated to 1 million actuations. The box features multiple pins that could be connected to trigger trim, lift plates, K-planes, and so on.
