Exclusive Advance gearbox by Advance Europe


Are you looking for a new gearbox? The vast majority of ships are equipped with a single lever to operate both the engine and the clutch with one hand. This makes it possible to use the throttle to put the clutch in both forward and reverse Advance Europe is the exclusive importer of these Advance gearboxes for Europe.

What is a gear box?

This type of clutch is a transmission that in most cases is coupled directly to the engine With the coupling it is possible to adjust the direction of rotation of the screw. This means that with this handy instrument you can make the boat sail both forwards and backwards, but also that you can stop the propeller. Without the gearbox you cannot reverse the rotation of the propellor shaft . If you want to sail forward, this is no problem, but to maneuver backwards, the coupling offers a solution In addition, the clutch ensures a fixed reduction in speed.(rpm) This is useful because boat propellers are usually designed for lower RPM than the idle RPM of most engines.

Is your gearbox broken?

How do you determine whether your clutch needs to be replaced? This depends on the type of coupling that is on your vessel.

Defect in a mechanical coupling

In a mechanical coupling, in most cases the rotating elements cause a defect or wear. You will hear a rattling sound from the engine or a whine from the clutch itself.

Defective by hydraulic clutch

A defect is more difficult to identify with a hydraulic clutch. You notice with a broken clutch that the mechanism slips more or that you achieve a different number of knots at a certain speed. Did you previously go 6 knots with the boat at a certain engine speed and now only 5 knots? Then there is a good chance that the clutch is broken.

Replacing the gearbox

A well-functioning ship is essential for maximum sailing pleasure. Daarom kan het behoorlijk frustrerend zijn als de koppeling niet optimaal werkt. If you have a defective mechanism, the drive will become uncontrollable. This can lead to dangerous situations. In that case it is important to overhaul the clutch. You can do this yourself or have it done by a specialist. Experience shows that replacing the clutch is not an easy job. Specialists immediately recognize the problem and have experience with replacing a clutch. The mechanism is completely disassembled, whereby all wear-sensitive and moving elements, such as gears, clutch plates, pistons, operating lever, plate drums and bearings are examined for excessive wear. Then the defective parts are replaced. All parts are then reassembled and your ship can safely return to the water.

Maintaining the gearbox

Good maintenance ensures that problems with the clutch are identified in good time. For example, make sure that the oil is at the right level. Dry running of a clutch causes faster wear and the mechanism overheats. Using the wrong oil or not changing the oil enough can also cause clutch problems. In addition, it is important that the coupling is correctly adjusted. For example, the engine should not be able to rev up when the connection to the clutch is created. Connect first, then the amount of gas on it. Of course, the way of sailing also plays a role in the life of the coupling. Putting a vessel at full throttle into reverse immediately is not ideal for the clutch. Let the motor come to rest before switching on the mechanism.

How does a gearbox work?

Two types of couplings are available: the mechanical and the hydraulic coupling.

The mechanical gearbox

The operation of the mechanical clutch is surprisingly simple. The mechanism has a main and an auxiliary shaft that are continuously connected by means of gears. If you go forward, the transfer takes place immediately. When sailing backwards, an extra cogwheel ensures that the direction of rotation is reversed. There is a small amount of oil in the mechanism which should be clean for best results.

The hydraulic gearbox

This mechanism works by means of hydraulic pressure. The multi-disc clutch is made of steel and bronze plates that are mounted alternately. These plates are rotated by the motor. In order to sail forward, the bronze plates are pressed against the propeller shaft, whereby the steel plates allow the bronze plates to move along. To sail backwards, a gear transmission reverses the direction of rotation. These gears are located on a shaft in the clutch. The hydraulic control works with pistons operated by oil pressure plate clutch.
