21809318 Control Panel | Genuine Volvo Penta Part

🔧 Product Description

The Boat Trim System (BTS), with its patented interceptor technology, gives perfect control over pitch and heel with rapid response, quicker onto plane, lower fuel consumption and a more comfortable ride. Add the Automatic Boat Trim option and the system takes over the task of keeping the boat correctly trimmed automatically. It is a match for almost all planing boats in the range of 17 to 40+ feet - outboard, sterndrive or inboard - and its compact design makes for an easy installation. The control panel is the intuitive, user-friendly helm interface for the system. It is a mandatory component of every installation and is already included in both the 300 mm and 450 mm kits.
