Toobop Ignition Starter Switch For Johnson Evinrude Push To Choke
Best for: Inboard/outboard engines using push‑to‑choke without a separate choke switch. This six‑terminal switch is designed for most OMC applications and can simplify ignition control by integrating choke into the starter circuit. The compact build supports side‑mounted controls common on mid‑size boats.
Why selected: It combines a push‑to‑choke feature with six terminals, enabling straightforward wiring for typical marine ignition setups. The durable construction supports salt exposure when used on saltwater boats.
Limitations: Availability of exact OEM parts varies by model; verify that your control box matches a six‑terminal configuration before purchase.
AUTOBABA 87‑88107A5 Boat Ignition Switch
Best for: Mercury outboards from 1994 onward that require 87‑88107 family replacements. The model emphasizes a marine‑grade housing and non‑conductive components to reduce short circuits in harsh marine conditions.
Why selected: It aligns with OEM part numbers, offering compatible form and function for common Mercury installations. The housing is designed to resist corrosion in saltwater operations.
Limitations: Some engines with non‑standard control boxes may need variant wiring; confirm your 6‑wire layout and terminal arrangement before buying.
HZSIFU Ignition Switch Push To Choke
Best for: Mercury/Sierra style engines requiring a 3‑position switch with six terminals. The switch supports a robust 12V system and provides choke integration that helps cold starts in varying climates.
Why selected: It lists compatible models and emphasizes reliable starting power with defined amperage specs for choke, ignition, and solenoid. The build uses marine‑grade materials for durability in salt spray.
Limitations: Performance depends on correct terminal wiring; miswiring can cause intermittent starting issues. Verify the exact model compatibility with your engine year and box.
Tutor Auto 87‑17009A5 Boat Ignition Switch
Best for: Mercury outboard control boxes that require a 3‑position, six‑wire push‑to‑choke replacement. Includes two keys for secure operation and offers corrosion protection for extended service life.
Why selected: It matches OEM replacement numbers and emphasizes a non‑conductive housing to reduce short circuits. The 6‑wire design supports straightforward installation in many Mercury setups.
Limitations: Some models may need minor adapter wiring; verify the exact OE part number compatibility (87‑17009A5, 87‑17009A2, etc.) before purchase.
IVONNEY 87‑88107A5 Boat Ignition Switch With Key
Best for: Mercury push‑to‑choke systems needing a six‑wire base with two keys. The design emphasizes marine‑grade polyester construction and a potted base to resist moisture and shocks.
Why selected: It covers common Mercury OE part numbers and includes a choke function in a compact six‑wire design, aiding reliable starts in challenging conditions.
Limitations: Ensure your control box supports the included wiring scheme; some side‑mounted panels require compatible mounting depth.
Marpac Ignition Switch 7‑1150 Push To Choke
Best for: Mercury/Mariner applications using a six‑terminal setup with push‑to‑choke functionality. The switch is designed to fit most common outboard configurations with six spade terminals.
Why selected: It provides a straightforward replacement option when upgrading an older ignition system that lacks a choke control or has worn components.
Limitations: Availability of exact 7‑1150 equivalents can vary by seller; verify the specific wiring pattern and terminal layout for your engine model.
Buying Guide: Key Purchase Considerations
- Compatibility: Confirm the part number family (87‑88107, 87‑88107A5, etc.) and that the switch is designed for Mercury or OMC systems used on your boat.
- Wiring and Terminals: Look for a six‑terminal design with a Push‑to‑Choke feature and a 3‑position OFF/ON/START configuration to ensure seamless starting and choke control.
- Construction: Prioritize marine-grade polyester housings, non‑conductive interiors, and corrosion resistance for saltwater use.
- Keys and Security: Some models include two keys; this improves ignition reliability and reduces the risk of accidental switch cycling.
- Mounting and Fit: Check mounting depth and panel compatibility (side mount vs. push‑button panels) to ensure a clean installation.
- Reliability: Favor designs with potted bases and robust seals to resist moisture ingress and vibration common on boats.
FAQ
- What is “push to choke” and why is it advantageous? It integrates the choke function into the ignition switch, eliminating a separate choke handle and simplifying starting, especially in cold conditions.
- Are six‑wire switches standard? Yes, most marine ignition switches use six terminals to manage ignition, solenoid, and choke circuits reliably.
- Can I replace Mercury OEM parts with aftermarket switches? In many cases, yes, if the part numbers and wiring scheme match your control box; always verify compatibility before purchase.
- Do these switches protect against corrosion? Modern marine switches typically use marine-grade housings and seals designed to resist salt spray and moisture, extending life in harsh environments.
- What should I verify before buying? Confirm model year compatibility, control box type, and that the product supports your engine’s choke and ignition wiring scheme.
