Troubleshooting & FAQ

Q: How do I confirm this seal kit fits my Volvo Penta sterndrive?
A: Verify your engine model against the compatibility table above. Cross-reference your existing OEM part number (22086, GLM 87830, or Volvo 925258) to ensure a match. Note that this kit is designed for single prop shaft applications and is not compatible with DP-drives.

Q: How often should I replace my prop shaft seals?
A: Replace prop shaft seals during routine sterndrive maintenance, typically every 2–3 years or 200–300 hours of operation, or sooner if you notice water intrusion, abnormal vibration, or visible seal deterioration.

Q: What are the signs that my prop shaft seal is failing?
A: Common symptoms include water in the sterndrive housing, leaking fluid around the prop shaft area, unusual noise or vibration during operation, and visible cracks or wear on the seal components during inspection.

Q: Can I reuse the old seals if they look intact?
A: No, always install new seals when servicing the prop shaft assembly. Seals compress and conform to the shaft over time, and reusing them may result in improper sealing and water intrusion.

Q: Do I need any special tools to install this seal kit?
A: Basic hand tools are typically sufficient, including wrenches, seal drivers or suitable drift punches, and a torque wrench. Marine-grade grease and cleaning solvent are also recommended for proper installation.
