3580805 Key | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta key for older propeller shafts, from the Marine Propulsion group, weighing 0.043 kg. It measures 10 mm by 12 mm across, 3 mm and 6 mm in height and 80 mm long, and suits a 40 mm shaft. The accessories catalogue introduced these keys so that older shafts with a 10 mm key slot can take the new ISO standard bronze propellers, and this is the larger of the two sizes listed, with 3580804 covering 30 mm shafts.
