Troubleshooting & FAQ
How do I confirm this kit fits my sterndrive?
This kit fits specific Volvo Penta DPH, DPI, and DPR models. The best method is to match your original part number to 23553896. For DPH-D vs DPH-D1, please check your sterndrive's serial number against the ranges in the compatibility table.
What are the signs of a failing propeller shaft seal?
Common signs include milky or creamy gear lube (indicating water), visible oil leaking from the propeller shaft area, or finding fishing line tangled in the seals. Regularly checking your gear oil is the best way to catch a leak early.
Can I reuse old washers or seals?
No. Always replace all components included in the kit. Reusing old seals or washers can lead to premature failure and costly water damage to your sterndrive.
What is the recommended replacement interval?
It's best practice to inspect seals annually or every 100 hours. They should be replaced preventively whenever the lower unit is serviced for other reasons or if any signs of wear or leakage are found.
Why is the distinction by serial number important for DPH models?
Volvo Penta made design changes during the production run of the DPH series. This kit fits DPH-D models up to serial number 3020295797 and DPH-D1 models from serial number 3020295798 and up. Using the wrong kit can result in an improper fit and seal failure.
Is the included grease necessary?
Yes. The supplied grease is specifically formulated for lubricating the sealing rings during installation. This prevents damage to the seals and helps ensure a proper, watertight fit on the propeller shaft.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). It's built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, it's batch-inspected for consistency.
