12V Electrical Solenoid Relay for Yamaha

This 12V electrical solenoid relay, cross-referenced as 688-81950-10-00, is a direct-acting starter relay that routes battery power to the starter motor for reliable engine cranking. Designed for Yamaha outboard applications, this relay ensures a positive electrical connection every time you turn the key. It serves as a robust replacement for worn or failed relays on compatible Yamaha models.

Overview

This 12V electrical solenoid relay is a crucial component in the starting circuit of compatible Yamaha outboard motors, managing the high current flow needed to engage the starter. It operates by using a small control signal to close a heavy-duty internal contact, safely delivering full battery voltage to the starter. This relay is intended for boat owners and technicians maintaining specific Yamaha outboard models from the mid-1980s.
