The 14,000 RPM Self-Powered Timing Light (replacing Mercury OEM Part Number 99379) from Buckshot Racing #77 is built for accurately checking ignition timing on high-performance two-stroke outboard engines—especially the kind that live at high RPM and demand repeatable, precise setup.
Unlike traditional timing lights, this self-powered design helps eliminate the mess and risk of long battery leads and tangled wires. That’s a big deal on race rigs running 24V or 36V trim and starting systems, where accidental shorts can ruin a day (or a harness).
With the Buckshot Racing #77 light, setup is simple: you connect one lead to the spark plug wire and you’re ready to verify and adjust timing without dragging external power wires across the boat.
Visibility is handled by a high-intensity strobe, a power indicator, and a precision locator beam that stays usable even in bright daylight. The locator beam is controlled by a separate button so you can aim exactly where you need while setting ignition timing.
Power comes from two (2) included D-cell batteries, so there’s no need for an external 12V source. That makes it a practical timing light for trackside, shop, and lakeside tuning—especially when you’re moving from motor to motor.
Compatibility is broad across two-stroke outboard ignition systems, including CDM, ADI, CDI, and older magneto-based ignitions. It’s a strong fit for common performance and racing outboards from Mercury / Mercury Racing, Yamaha, OMC, Evinrude, and Johnson.
A slide-style inductive pickup clip securely attaches to nearly any spark plug wire, helping maintain a stable signal for accurate readings. This unit is designed to deliver consistent timing flashes all the way up to 14,000 RPM, making it ideal for high-revving race outboards and performance two-strokes.
It’s also designed as a direct replacement for the Mercury Marine / Quicksilver / MerCruiser timing light (OEM part number 91-99379) and the Sierra 18-9802 portable timing light, offering premium performance and strong value compared to typical MSRP ranges of $189.98 to $279.99 for those units.
Upgrade your marine toolset with a self-powered timing light built for precision ignition timing, race-safe setup, and high-RPM two-stroke outboard tuning.
