Toobop Ignition Starter Switch for Johnson Evinrude Push to Choke
Best for: boaters using Johnson or Evinrude inboard/outboard configurations who want a straightforward push-to-choke function with six terminals. The switch is described as compatible with most OMC inboard/outboard applications and includes a push-to-choke feature that eliminates a separate choke control. This simplifies wiring for a cleaner dash and reduces switch failure points. Use this if your boat’s control box matches the 6-terminal layout and you need integrated choking.
Caution: Compatibility may vary by model year and panel cutout. Verify the six-terminal configuration matches your existing wiring harness before purchase.
SEACHOICE Ignition Starter Switch for Johnson/Evinrude
Best for: sailors or anglers with standard OMC inboard/outboard layouts seeking a dependable push-to-choke ignition. Features include a six-terminal design and a push-to-choke function that reduces the need for a separate choke switch. SEACHOICE is known for broad compatibility with Johnson/Evinrude installations and ease of replacement.
Limitation: Exact fit depends on the control box model; confirm panel cutout and terminal arrangement match your engine’s wiring diagram.
AUTOBABA 87-88107A5 Boat Ignition Switch with 2 Keys
Best for: Mercury outboard motors from 1994 onward, with a durable marine-grade housing and corrosion protection. The switch includes two keys and a six-wire, three-position (Off/Ignition/Start) design with push-to-choke functionality. This option is suited for owners replacing worn OEM parts and seeking corrosion-resistant materials.
Caution: Verify the OEM part numbers (87-88107, 87-88107A5, 7-1155) match your Mercury model to ensure proper fitment.
Marpac Ignition Switch 7-1150 Push to Choke
Best for: Mercury and Mariner applications requiring a 6-spade terminal setup. The push-to-choke feature is designed to streamline starting while maintaining compatibility with common Mercury control boxes. This switch is a solid option when a simple, six-terminal design is important for your dash wiring.
Limitation: While widely compatible, always confirm panel fit and wiring color codes align with your engine’s existing harness.
Tutor Auto 87-17009A5 Boat Ignition Switch Replacement
Best for: Mercury Outboard controls from 1994 and newer, offering a 3-position, six-wire design with push-to-choke. The unit emphasizes corrosion protection, with a non-conductive housing designed to prevent shorts and extend life in marine environments. It’s a practical replacement when the OEM switch shows stiffness or corrosion issues.
Choose this if you need a direct Mercury replacement that aligns with early Mercury part numbers like 87-88107A5 and similar, and you want robust corrosion resistance.
Buying Guide
What should I check before buying a push-to-choke ignition switch?
- Panel fit and mounting: Confirm the switch diameter and panel cutout fit your boat’s dashboard or control box.
- Wiring configuration: Most switches use 6 wires. Ensure the terminal layout matches your existing harness to avoid rewiring.
- Compatibility: Verify that the switch supports your engine brand (Mercury, Mariner, Johnson/Evinrude/OMC, etc.) and model year range.
- Choke integration: If you rely on a dedicated choke control, ensure the switch provides a push-to-choke function that meets your system’s design.
- Housing and materials: Marine-grade polyester housings and corrosion-resistant finishes extend life in salt air and spray environments.
- Keys and security: Some models include two keys—consider whether you need a keyed switch or a simple push-to-start
How to choose between models
- Best for universal OMC systems: Look for six-terminal, push-to-choke with proven compatibility across Johnson/Evinrude inboard/outboard options.
- Best for Mercury-specific setups: Focus on Mercury-compatible part numbers and corrosion-resistant housings to match OEM expectations.
- Best for durability in harsh environments: Prioritize polyester or marine-grade housings and robust sealing features to resist saltwater exposure.
- Best for ease of replacement: Choose models with common OEM part-number compatibility to simplify future maintenance.
Installation considerations
- Follow the engine manufacturer’s wiring diagram for correct terminal connections.
- Double-check ground connections to minimize ignition faults.
- Test the choke function before finalizing the dash layout to confirm smooth operation.
FAQ
- Q: Do push-to-choke switches work with all outboard engines?
A: They work with many OMC inboard/outboard setups, but always verify compatibility with your specific engine model and control box. - Q: How many wiring wires do these switches typically use?
A: Most options use six wires, matching a standard three-position switch (Off/Ignition/Start) with choke control. - Q: Are these switches weatherproof?
A: Many models use marine-grade housings designed to resist corrosion, but confirm IP ratings or sealing features for your environment. - Q: Can I replace an OEM Mercury switch with a non-OEM model?
A: Replacement parts should match OEM part numbers or a compatible control box wiring to avoid startup or safety issues. - Q: Is a keyed switch better for theft prevention?
A: Keyed switches add security, but the choice depends on your boat’s security needs and the specific installation. - Q: What if my panel cutout is not standard?
A: Check the switch diameter and mounting depth; some models offer flexible mounting options or adapters.
