3868728 Drive | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta sterndrive with the 1.68:1 gear ratio for the DP series, listed for one application. It consolidates two earlier numbers, 3803406 and 3868672, catalogued as an Aquamatic drive and a remanufactured Aquamatic drive. The published weight of 137.4 kg is roughly double what comparable drives carry, so it should not be used to identify the unit.

🛠️ Service Notes

• One of the numbers it replaces was a remanufactured drive, so confirm with us whether this is supplied new or as an exchange unit
• The DP-S1 unit 3868604 also carries a 1.68:1 ratio and is published at about 58 kg, less than half this figure, so order by the drive designation and ratio and not by weight
