Troubleshooting & FAQ
How do I confirm this fits my Suzuki engine?
This assembly fits most Suzuki 4-stroke models from 15 HP to 250 HP, made between 1998 and 2011. The best way to confirm is to match your existing part number to one of the replacements listed: 37110-93J00, 37110-93J01, or 37110-93J02. Also, check your specific engine model against our compatibility table.
What are common signs of a failing ignition switch?
Symptoms include the engine not cranking, intermittent stalling, the key feeling loose or getting stuck, or electrical accessories losing power. If you have to jiggle the key to start the engine, the internal contacts are likely worn.
