23983553 Complete 300mm Trim Tab Kit Trimming Raft | Genuine Volvo Penta Part

🔧 Product Description

A complete electronic interceptor trim-system package for a single installation with one helm station. The compact 300 mm interceptors mount across the transom and provide rapid control of both pitch and heel, helping a planing boat reach the plane sooner, run with a more level attitude and maintain improved comfort and efficiency. The system uses self-contained electric interceptor actuators rather than external hydraulic cylinders. It is suitable for boats powered by outboards, sterndrives or inboard shafts and is not restricted to a particular engine brand.

🚤 Compatibility

• Engine Family: D, V
• HP Range: 110-430 HP

📋 Kit Contents

• Interceptor kit, 300mm, one helm station

🔌 Function

The interceptors extend vertically into the water flow to generate lift at the stern. Independent port and starboard control corrects vessel list, while simultaneous movement adjusts running trim and pitch.

⚠️ Common Signs of Failure

• One interceptor does not deploy or retract
• Port and starboard response becomes uneven
• Control panel is unresponsive or displays a system fault
• Interceptors move intermittently because of cable, power or control-unit faults
• Vessel develops persistent list, slow planing or excessive bow rise
• Interceptors fail to retract when the system is shut down

🛠️ Service Notes

• This 300 mm BTS kit packages the two interceptor units, control panel, control unit and cabling for one helm station — check what a prior installer left in place before ordering a second kit, and confirm you hold the current 23983553 number rather than one of the superseded 21914554, 21534532, 21248221, 21175615, 3593903 or 3841717 packages
• The interceptors are self-contained electric actuators, not hydraulic rams, so there is no fluid to bleed or top up — if trim response is slow or uneven, check the actuator wiring, connectors and control unit rather than looking for trapped air as you would on a hydraulic trim system
