Ignition Starter Switch for Johnson Evinrude Push to Choke
This switch is designed for most OMC inboard/outboard applications with a push-to-choke feature. It provides six wiring terminals for flexible electrical connections. Best for boaters upgrading older Johnson/Evinrude systems that rely on a choke function integrated into the ignition switch. A potential limitation is availability of replacement parts in older models; verify compatibility with your control box before purchase.
Seachoice Ignition Starter Switch
Seachoice offers a practical push-to-choke ignition switch suitable for a variety of OMC inboard/outboard setups. Its six-terminal layout supports common wiring schemes and corrosion-resistant construction helps in saltwater environments. Choose this if you want a straightforward swap that aligns with many aftermarket wiring harnesses. Be mindful that exact terminal color coding or harness compatibility can vary by model year.
87-88107A5 Boat Ignition Switch (Mercury Compatible)
Autobaba’s 87-88107A5 is engineered for Mercury outboards from 1994 onward. It features a non-conductive housing to reduce short circuits and a marine-grade construction designed to resist corrosion. It’s best for Mercury- or Mercury-compatible control boxes that require a 6-wire push-to-choke switch. A limitation is potential misfit with non-Mercury systems—confirm OEM part numbers before ordering.
Marpac Ignition Switch 7-1150 Push to Choke
Marpac’s 7-1150 is designed to fit a wide range of Mercury and Mariner applications with six spade terminals for reliable electrical connections. The push-to-choke feature simplifies starting workflows, especially for boats with manual choke systems in older engines. It’s best for Mercury/Mariner users seeking a durable, easy-to-wire replacement. Limitations include variations in panel cutouts; verify the 6-wire configuration matches your harness.
87-17009A5 Mercury/Mariner Replacement
Tutor Auto offers a Mercury-compatible ignition switch with 6 wires and a push-to-choke design. It includes two keys and is intended for Mercury/Mariner outboard systems that need a reliable replacement part. This option is well-suited for users who want a straightforward, commonly compatible solution. A potential caveat is ensuring the part number alignment with your control box—check EF numbers and compatibility carefully.
Manutex Si-erra/Mer-Cucy Push-to-Choke Switch
Manutex’s model accommodates multiple popular brands, including Si-erra and Mercury, with a 3-position switch and push-to-choke functionality. It suits boats using older or varied control boxes that require a flexible wiring approach. Better for mixed-brand fleets; avoid if your engine is a strict OEM-only setup and requires a single-brand switch.
Buying Guide: Push-To-Choke Boat Ignition Switches
- Compatibility: Confirm the switch matches your control box’s OEM numbers (for Mercury, MerCruiser, Johnson/Evinrude, etc.). Look for 6-wire or 3-position configurations and ensure your harness supports push-to-choke.
- Construction: Marine-grade polyester housing and corrosion-resistant contacts extend life in saltwater environments. Non-conductive housings can prevent shorts caused by wiring faults.
- Wiring & Terminals: Check the number and type of terminals (6-spade vs 6-wire) and whether your existing wiring harness uses standard color codes. Some models include waterproof base or sealing features for added durability.
- Panel Fit & Mounting: Verify the panel cutout size and mounting depth. Some switches replace older units with the same footprint, while others may require panel modification.
- Keys & Security: Two-key sets aid quick ignition and theft deterrence. Ensure keys are included if you need immediate operation after install.
- Maintenance: Push-to-choke functions may be less effective if cables or linkages are worn. Inspect choke linkage and ignition wiring during installation.
- Limitations: Some options are model-specific. If you switch brands or engines, a universal-fit design may be preferable, but verify pinouts before purchase.
Frequently Asked Questions
- What is a push-to-choke ignition switch? A switch with a built-in choke function activated by pressing the switch, simplifying starting without a separate choke lever.
- Which boats benefit most from push-to-choke switches? Boats with older outboards or mixed-control boxes where a combined start/ choke control reduces complexity and potential failure points.
- Are 6-wire and 3-position switches interchangeable? They serve related roles but have different wiring schemes. Check your control box wiring diagram and part numbers.
- Can I mix brands when replacing an ignition switch? It’s possible in some cases, but it’s safer to match OEM part numbers or use a universal model tested for your engine family.
- What should I inspect before installing? Confirm compatibility, panel fit, proper sealing, wiring harness alignment, and the presence of a secure ground connection.
- Do these switches require professional installation? Not strictly, but basic electrical wiring and marine-grade sealing are important; consider professional service if you are unsure.
