On a friend's Sea Ray, the stop switch clicked off while running causing the engine to shut down. We reset the switch, and got underway again, but I'm wondering how those switches work. This switch has a canister the size of a decent sized soup can plus at least a couple of wires going into it. Does tripping the switch stop the fuel flow, block the air intake, do both, or something else/more? Also, I'm led to believe installation on a Sea Ray might be different from another manufacturer; is that reasonable? Thanks.
Fuel Shutoff Solenoid The "soup can" is a simple solenoid that pulls a rod connected to the fuel delivery switch. It's very easy to pull manually should you ever have a problem with the engine not shutting down. ROCKY
So, then, it's an electrical fuel delivery shut off only. No damping of the intake air. Got it. Many thanks.
The soup can pulls the governor and rack to "no fuel" and the engine dies. There is usually a push button that has to pushed to energize the solenoid and shut the engine down. There is a emergency shut down that is usually a pull cable. This closes a flapper on top of the blowers and stops/reduce the air to the engine. I have had this release once and scared the stuff out of me. This does require a manual reset on top of the motor. ,Ralph
