Troubleshooting & FAQ

How do I confirm this fits my engine?
The best method is to compare your original part number to the ones listed in our "Part Number Cross-Reference" table. Additionally, check the "Compatible Engine Models" tables to ensure your specific Suzuki model and year range are included.

Where is this ignition switch installed?
This switch is designed for installation in the boat's remote control box, not directly on the engine.

What are common signs of a failing ignition switch?
Symptoms include the engine failing to crank or start, the key feeling loose or difficult to turn, intermittent power loss to accessories, or the engine not shutting off when the key is turned to the "Off" position.

What does the "Push-to-Choke" feature do?
When the key is in the "Run" position, pushing the key inwards activates the engine's choke or enrichment circuit. This is typically used to aid in starting a cold carbureted engine.

OEM vs. Aftermarket?
This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

How fast do you ship and how much does it cost?
We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.

Great shelves!
Size: 24x5.8, Color: Black, Size: 24x5.8, Color: Black
I love these shelves (I purchased 6 shelves total). The size I got was perfect, looks phenomenal, & quality is great too! Only negative thing I’d say is that it could be difficult for some people to set up as it needs to be leveled, & can be hard to align with other things since the part that attaches to the wall is separate from the shelf (due to its floating design) but once it’s up, it looks great. Definitely good value for money with its quality. I have them to hold up decorations/toys, & you think some of my shelves have about 5lbs of stuff on it & I’ve had no issues, so functionality is good.

Good enough
Size: 15x6.8, Color: Black
As cheap as the day is long but functional. These are basically made out of highly compressed paper and finished to feel like wood. The first one I put up was good with a little tilt to the back which is fine. The second one has a more severe tilt and I had to bend the bracket down to decently level it out. They are sturdy enough to hold quite a bit of weight and look good for what they are. I'm not impressed but I'm also not disappointed, the price is a bit steep for what they are but they serve their purpose.
