A wide selection of engines, clucthes and Volvo Penta Z drives plus precise instruments and gears  were developed through enormous research and testing and therefore guarantee impeccable products. All accessoires and spare parts come from the same process - carefully designed, thouroughly tested and attested to ensure compatibility with engines and Volvo Penta drives. Non-original spare parts have not been attested and might disrupte this harmony and increase the risk of excessive wear-and-tear and that also means increased repair expenses. These are the reasons to use only original Volvo Penta spare parts and accessoires.
