# 21936286 Trimming Raft | Genuine Volvo Penta Part

## 🔧 Product Description

Load-transmitting or actuation assembly engineered for the specified Volvo Penta propulsion or cooling-drive system.

## ⚙️ Key Features

-   Factory torque and alignment specification
-   Designed for the original shaft or actuator geometry
-   Marine-duty materials
-   Related bearings, seals and fasteners must be inspected

## 🔌 Function

Supports and actuates the drive trimming mechanism under hydraulic pressure.

## ⚠️ Common Signs of Failure

-   Vibration or abnormal noise
-   Slippage or delayed engagement
-   Hydraulic leakage or trim fault
-   Cracked flexible elements
-   Excessive backlash or wear

## 🛠️ Service Notes

-   This is the blade of the boat's trim system rather than any part of the drive; it is the surface the trim cylinders push down against the water flow under the hull.
-   Trim flaps are sized and handed and work as a pair - fit the same size on both sides and check the opposite flap and its cylinder mounting at the same time, or the boat will trim unevenly.
-   The mounting fixings pass through the transom below the waterline: bed the flap and its fasteners on a suitable marine sealant, and check that area for water ingress after the boat is first put back in.
-   Inspect the hinge and the cylinder attachment for corrosion and for play before deciding the flap alone is at fault - the blade lives in seawater and takes the load of the whole trim system.
-   Check the trim system through its full travel after fitting and confirm the flap returns fully up before hauling out or trailering.
