SPACER 61A-45538-00

Function and technical context

This spacer is part of the engine mounting structure, ensuring the correct positioning and alignment of critical components in the power transmission chain. Its function is to maintain the precise distance between elements of the engine block and the gearbox, ensuring that there is no unwanted contact between moving and fixed surfaces. A worn or damaged spacer compromises powertrain alignment, resulting in excessive vibrations, accelerated bearing wear, and possible leaks at adjacent joints. The integrity of this component is essential to prevent engine power from being dissipated in parasitic movements instead of being efficiently transmitted to the propeller.

When to replace this part?

Symptoms of deterioration include vibrations perceptible through the hull during navigation, metallic noises in the gearbox area and abnormal play between adjacent components detectable during inspection at the dock. Although there is no fixed maintenance interval like filters, it is advisable to check the condition of the spacer at each seasonal inspection, especially after navigation in murky waters or after having suffered impacts. Preventive replacement is a minor investment that avoids costly repairs resulting from transmission misalignment.
