Full model list at the end of this description.

⚙️ Key Features

• IPS-A marine propulsion application
• Fibreglass construction
• Factory drive-opening and mounting geometry
• Designed for structural bonding into the hull
• Maintains drive alignment and sealing-surface position
• Installation requires Volvo Penta hull-preparation procedures

🔌 Function

The insert creates the structural and watertight hull interface through which the IPS drive is mounted.

⚠️ Common Signs of Failure

• Cracking or delamination
• Water leakage around the drive opening
• Drive misalignment
• Poor laminate bond to the hull

🛠️ Service Notes

• This is the fibreglass insert used for IPS-A installations, not the aluminium version used elsewhere in the Hull Insert range - the galvanic-compatibility checks needed for the aluminium inserts do not apply here, but the bonding and surrounding hull laminate still need inspecting
• At 23.258 kg, this is a structural, below-waterline fitting - follow Volvo Penta's specified hull-preparation and bonding procedure exactly, renew the sealant and fixings on refit rather than reusing them, and arrange lifting support before removal
