Seachoice Heavy-Duty 3-Position Ignition Switch – Brass, Off/Ignition/Start
A heavy-duty keyed ignition switch with a brass body for long-term corrosion resistance in marine environments.

The threaded stem mounts securely through panels up to 1 inch thick, and two keys are included.
The 13/16"-20 threaded stem and 1 ⁷⁄₃₂" stem length fit standard helm panel cutouts used across most inboard and outboard-equipped boats.

Parts Desk Insights
Best Use Case: This is the right switch for inboard and sterndrive helm panels that need a straightforward Off/Ignition/Start sequence without an accessory position or choke function. The brass body makes it a more durable choice than plastic-housing alternatives in saltwater environments. If your engine requires a 4-position switch with an Accessory position, the 4-Position Keyed Ignition Switch (50-11801) is the better fit. For outboard engines with a push-to-choke magneto ignition, see the Magneto Ignition Switch (50-11821).
