Genuine Volvo Penta adjusting washer 3.65 mm thick, from the Engine group, listed for 21 applications across AQ and BB series engines. At 0.034 kg it is the heaviest of the graded series, which runs from 3.55 mm (463551) up to 4.15 mm (463563), so the published weights clearly do not follow thickness.
