YANMAR V 150KG ENGINE SUPPORT

Function and technical context

The engine support in "V" configuration is the structural element that joins the engine block to the boat's bedplate, absorbing and dissipating the vibrations generated during the operation of the propeller. It works within the mounting and force transmission system, acting as a damping interface between the engine and the hull, and preventing vibration frequencies from propagating to the naval structure. A deteriorated support compromises the alignment of the drive shaft, causing premature wear on the coupling, buttress and horn retainers, in addition to considerably increasing the level of noise and vibration perceived on board. The "V" geometry of this support provides simultaneous lateral and longitudinal support, guaranteeing that the engine-transmission assembly maintains its correct angular position even under dynamic loads in navigation.

When to replace this part?

The most common symptoms of an engine mount in poor condition are: a noticeable increase in vibrations transmitted to the hull, the appearance of knocking or resonance noises in the engine room and visible or progressive misalignment of the tail shaft. The elastomeric core of the support degrades over time due to continuous exposure to oil, fuel and marine humidity, so it should be inspected during each seasonal maintenance and replaced at the first sign of deformation, cracking or collapse of the rubber pad. Replacing the bracket preventively avoids costly secondary failures such as deterioration of the elastic coupling or damage to the stuffing box, which at sea can compromise the safety of the boat.
