278003012 Starter Solenoid for Sea-Doo GTR 230 1630 2020-2026

Starter Solenoid for Sea-Doo

This starter solenoid for Sea-Doo is a replacement electrical relay that sends battery current to the starter motor, referencing OEM part number 278003012 and fitting GTR 230 models with the 1630 engine from 2020 through 2026.

Overview

This starter solenoid for Sea-Doo acts as the switching relay between your battery and starter motor, delivering the high amperage needed to spin the 1630 engine on GTR 230 watercraft. It serves as a dependable replacement when the original solenoid fails to engage or cranks inconsistently. Owners of 2020 to 2026 GTR 230 models get a direct-fit starter solenoid built for marine starting duty.

Specs At A Glance

Good To Know

Q: What causes a starter solenoid to fail on a personal watercraft? A: Moisture intrusion, corroded contacts, and years of high-current switching gradually erode the internal disc and terminals. Symptoms often begin as slow or intermittent cranking before turning into a complete no-start.

Q: Can I install this solenoid myself? A: Yes, it replaces the OEM 278003012 unit using the same mounting points and wire connections, which makes it a job most owners can handle with basic tools. Disconnect the battery first and label the cables before removal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
