991659 Washer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta plain washer weighing 0.005 kg and listed for 101 applications across the IPS, D, V, DPH, DPI and DPR series. It is published with exactly the same weight and exactly the same fitment as the toothed washer 991660 — the only thing separating the two is that 991660 is the toothed pattern and this one is plain. Order by part number and by looking at the washer.

🚤 Compatibility

• Engine Family: IPS, D, V, DPH, DPI, DPR
• HP Range: 140-480 HP
