## 🔧 Product Description

Genuine fibreglass hull insert for Volvo Penta IPS-A propulsion installations. It is bonded or laminated into the vessel hull to form the engineered opening and mounting interface for the IPS drive and its sealing and clamping components.

## 🚤 Compatibility

-   **Engine Family:** D, IPS
-   **HP Range:** 260-480 HP

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
