Inductive Hour Meter for Gas Engine Lawn Mower Dirt Bike Motorcycle Motocross Snowmobile Karting Marine ATV Boat Outboard Motor Generator Waterproof Hour Meters (Red)

What It Is

This inductive hour meter tracks engine run time on gas-powered equipment—lawn mowers, dirt bikes, snowmobiles, generators, marine outboards, and ATVs. No wiring or battery needed; it clips onto a spark plug wire and reads ignition pulses to log hours.

Fitment & Compatibility

• Engine type: Works on any 4-stroke or 2-stroke gas engine with a spark plug wire. Not for diesels or electric motors.
• Spark plug wire: Fits wires 5–8mm diameter. Check your wire gauge before buying—too thick or too thin may not hold securely.
• Mounting: Self-adhesive back; clean, flat surface required (metal or plastic). Avoid mounting directly on hot engine blocks or near exhaust.
• No OEM/aftermarket restrictions: Universal design, no brand or model-specific fit. Works on any machine with a spark plug wire.

Before buying: Measure your spark plug wire diameter. If it’s larger than 8mm, you’ll need a different inductive pickup. Also confirm the engine has a spark plug wire (not a coil-on-plug system).

Key Things to Know

• Installation: Simple—wrap the pickup around the spark plug wire (anywhere between coil and plug), then stick the meter on a clean, dry surface. No tools or wiring required.
• Accuracy: Counts hours based on ignition pulses; works only when the engine is running. Will not track time while the engine is off.
• Sealing: IP65 waterproof rating for rain and splash, but not submersible. Avoid pressure washing directly at the meter.
• Battery: Internal battery lasts 3–5 years (non-replaceable). Once dead, replace the whole unit.

Should You Buy It

Yes, if you need a simple, no-wire way to track maintenance intervals on any gas engine with a spark plug wire. Ideal for lawn mowers, generators, and small engines where you’d rather not splice into the ignition. Not for diesel or coil-on-plug systems. At $11.49, it’s a low-cost, set-and-forget tool.
