Inductive Hour Meter with Crocodile Clip,Waterproof IP68 for Gas Engine Lawn Mower Generator Pressure Washer Marine ATV Boat Outboard Motor Dirt Bike

What It Is

This inductive hour meter tracks engine run time by clipping onto a spark plug wire—no wiring or battery needed. Designed for gas engines on lawn mowers, generators, pressure washers, marine outboards, ATVs, and dirt bikes.

Fitment & Compatibility

• Engine type: Gas engines with a spark plug wire (not diesel or battery-only machines).
• Spark plug wire: Works with standard 7mm or 8mm wires; may not fit thicker marine or shielded wires.
• Mounting: The clip attaches to the wire, not the engine block. Surface-mount with adhesive pad or screws (check included hardware).
• No deck size or brand limits—it’s universal, but verify your spark plug wire is accessible and not buried under covers or fuel lines.

Key Things to Know

• Accuracy: Inductive pickups can be finicky on engines with weak spark or high-RFI suppression. Test on a known run time to verify.
• Waterproof rating: IP68 is good for rain and washdowns, but the clip connection to the wire must stay dry—moisture there can cause false readings.
• Installation: Trivial—clip onto spark plug wire, mount the meter where visible. No tools needed beyond a screwdriver for mounting.
• Common gotcha: If the meter reads zero after a few minutes, the clip may be too loose or on the wrong wire (must be the plug wire, not coil input).

Should You Buy It

Skip it. The 2.8-star rating (7 reviews) and known accuracy issues make this a gamble. If you only need a rough hour log for a small engine and can afford a dud, it’s cheap enough to try. For serious maintenance tracking, spend a few dollars more on a wired or tach/hour combo with better reviews.
