Where does the power wire go on a Suzuki outboard?
The ECM in this smaller HP engine is powered of the Hot wire on the starter motor. Connects to the same terminal where the primary battery cable terminates. The ‘on’ and ‘start’ position of the Key Switch – power goes to the Gray wire. The Gray wire then proceeds to power just about everything on the engine, but the ECM.
Why is the neutral switch on my Suzuki outboard not working?
1) Spliced connections that have gone bad. Connectors not waterproofed that allow for unseen corrosion. 3) Ground wire fails. 6) If you have power to the ECM and starter fails to kick in, one of several more reasons can relate to the neutral switch.
What does the ignition switch do on a Suzuki outboard?
The ignition switch does several things- in the ‘ON’ position it is the primary power source to the ECM. At this point, for 4 cycle engines, a relay turns on the high pressure fuel pump. You should hear this pump.
What causes a Suzuki outboard to lose power?
1) Spliced connections that have gone bad. Connectors not waterproofed that allow for unseen corrosion. 3) Ground wire fails. 6) If you have power to the ECM and starter fails to kick in, one of several more reasons can relate to the neutral switch. Intermittent power loss can be difficult to find..

Is it safe to use white wire starter on Suzuki?
No, it is NOT the recommended method from Suzuki. The ECU is sensitive to voltage and the risk is that the starter will expose it to voltage drop. Thanks Moonlighter. That makes sense.
How does a remote trim switch work on a Suzuki?
You hit the remote trim switch to trim the engine up/down and nothing is working. The wiring to the trim switch relay is independent of the ignition wiring but shares the same WW power feed. This allows you to raise and lower the engine without turning on the ignition.

Where does the gray wire go in a Suzuki outboard?
From the ignition switch “ON” position, the gray wire feeds back to the ECM -and is the power source for the ECM. First let’s look at the trim switch. You hit the remote trim switch to trim the engine up/down and nothing is working.

How to troubleshoot a Suzuki outboard motor problem?
1 Motor Won’t Start. Inspect the primer bulb if the engine is not starting. If there is no resistance, fuel is not entering the engine. 2 Power Loss. Check the spark plugs and filter if there is a sudden and noticeable drop in power while the engine is at full throttle. 3 Vibrations. Inspect the propeller for damage. …
