Troubleshooting & FAQ
How do I confirm this screw fits my specific Volvo Penta model?
The most reliable method is to match your original part number to 984068 or the superseded number 956591. While this part is listed for DP-G outdrives, it fits many other models. Always compare the photos and specifications to your old part before ordering.
What are the signs that a hex socket screw needs replacement?
Indications include visible corrosion, a stripped or rounded hex head, or if the screw has become loose and fails to hold torque. It's good practice to replace critical hardware like this whenever the component it secures is being serviced.
What tools do I need for installation?
You will need a standard hex key (Allen wrench) of the correct size. Using the exact size is critical to avoid stripping the socket head. A torque wrench is also highly recommended to tighten the screw to the manufacturer-specified torque.
