Description
Suzuki 36665-87L10 SMG4 Mechanical Multi-Engine Gauge Adapter
The Suzuki 36665-87L10 is a mechanical multi-engine adapter built for SMG4 (Suzuki Multi Gauge) systems. It aggregates mechanical gauge signals — such as tachometer and cruise control outputs — from multiple engines into a unified data stream for digital gauge systems.
Compatibility & Applications
- Used in multi-engine outboard configurations (twin or more) to centralize mechanical gauge signals
- Integrates with Suzuki SMG4 color gauges and control systems
- Suitable for compatible Suzuki outboards with mechanical/tach outputs to digital gauge networks
Key Features & Benefits
- Combines mechanical signal lines into a single channel for simpler wiring
- Enables synchronized reading across multiple engines on one display
- Compact OEM-grade construction built for marine environments
- Plug-and-play installation — no software configuration required
