Description⚡ Electronic Ignition Conversion Kit | Part #1146A | Fits Mercruiser, OMC, Chris Craft, Universal & Industrial Engines | Double Spark Voltage
Tired of fiddling with breaker points that wear out, cause misfires, and leave you stranded? Whether you're restoring a classic Chris Craft runabout, keeping a trusty Mercruiser I/O on the lake, or maintaining industrial forklifts and farm tractors, this electronic ignition conversion kit is the upgrade you've been looking for. It drops right into your existing distributor — no complicated rewiring, no fabrication. Just remove the points, install the sensor module, and enjoy a stronger, more reliable spark that boosts horsepower, improves fuel economy, and extends spark plug life. Old-school simplicity meets modern performance.
✅Key Features
🔧Direct Drop-In Replacement— Engineered to replace traditional breaker points without modifying your distributor. No cutting, no splicing, no external boxes to mount. Simple swap, done in under an hour.
⚡Doubles Spark Energy— Delivers twice the voltage to your spark plugs compared to stock points. Hotter spark means more complete combustion, smoother idle, quicker throttle response, and easier cold starts.
⛽Better Fuel Economy & More Power— A stronger, longer-duration spark burns fuel more efficiently. Many users report noticeable gains in low-end torque and a small but real improvement at the pump.
🔋Longer Spark Plug Life— Reduced plug fouling and cleaner burning means you'll go longer between plug changes — a real money-saver for fleet and commercial operators.

🇺🇸Why US Buyers Choose This
🚤Weekend Boaters & Anglers— Nothing ruins a Saturday on the lake like a no-start. This kit eliminates the #1 cause of ignition failure on older Mercruiser and OMC sterndrives. Get on the water faster, stay longer.
🔧DIY Restorers— Working on a classic Chris Craft or a vintage Universal Atomic Four? This is the clean, period-correct upgrade that keeps the original distributor housing but ditches the points headache.
🏗️Fleet & Shop Owners— Running Clark forklifts or Allis-Chalmers industrial equipment? Solid-state ignition means less downtime, fewer service calls, and lower long-term maintenance costs.
💰Save on Tune-Ups— Points need replacing every season (sometimes more). This conversion pays for itself after just one avoided tune-up — and keeps paying dividends for years.
⛽Fuel Savings Add Up— On a boat that guzzles fuel, even a 2–3% efficiency gain makes a difference over a summer. Cleaner burn, more power, fewer plug changes — it's a win all is a direct replacement for distributors currently running breaker points. It isnotfor engines already equipped with factory electronic ignition (e.g., Delco HEI). Always confirm your engine's serial number range and existing ignition type before ordering. If unsure, send us a photo of your distributor or current points assembly — we're happy to verify fitment.
👉 Confirm your engine is on the list, match your part number to 1146A, and add to cart today — fire up your engine with confidence and leave points in the past!
