PROBLEMS CAUSED BY PROPELLER

 

Vibrations

If you’re a proud boat owner (no matter how big and what it’s like - it’s yours), and you’re bothered by the black smoke left behind, it’s time to do something about it.

An overloaded engine has a significantly reduced service life, and in addition to throwing smoke fuel into the wind, black smoke will seriously jeopardize your driving pleasure.

By modifying and optimizing the propeller, we completely solve the problem of engine overload, which will result in lower consumption and a more comfortable ride.

OVERLOADED ENGINE

The vibrations are not only unpleasant, but also a sign of propeller inefficiency. They can be caused by inaccuracies in pitch, propeller surface, section shape and propeller imbalance.
Prop Scan allows us to identify and eliminate these irregularities, resulting in a smoother ride, a more efficient and often faster propeller.

CAVITATING PROPELLER

Propeller-induced cavitation causes vibration, noise, and serious damage to the propeller. Can this be avoided?

The problem of cavitation can be divided into two categories. Cavitation caused by the propeller and cavitation caused by the ship itself (i.e. cavitation caused by hull shape, various additions and modifications ).

If the cavitation is caused by a propeller, we can measure and test your propeller using the Prop Scan system and show you the cause and by changing the design of the propeller blade we will solve the cavitation problem

INCREASES IN FUEL CONSUMPTION

Does your boat use more fuel than the recommended amount?

Poor class propellers increase fuel consumption.

The ISO Class S propeller consumes on average 10-15% less fuel than the ISO Class III propeller.

UNDERLOADED ENGINE

When the engine speed is higher than the maximum prescribed speed, the engine does not develop maximum power.

In other words, don’t get the optimum out of your engine.

In most cases, this means it can be obtained quickly.

SINGING PROPELLER

Some propellers produce high-frequency sounds at certain engine speeds that sound like singing.

At best, this can be uncomfortable, but if this happens at the revs you drive most often, this will be unacceptable. In most cases, there is a cure for this.
