  • INFO
  • Gap your spark plugs at .055 and go! No extra parts to buy (except the plug-in wire for your power and the tach if you don't already have one) as this is a complete engine ignition system with the powerful coil in the cap. Ships from our TN warehouse or you can pick it up in Memphis. Good up to 10,000 RPMs! 

    Fits Mercruiser, OMC, Volvo, Pleasurecraft, Yamaha, Crusader, some ChrisCraft, and most others using 305 thru 454 small and big block Chev V8 engines as their base. Works with Alpha1 & Cobra drives too. FREE SHIPPING to all 50 states too.

    NOTE: This distributor rotates the same direction as automotive but has a reverse-cut drive gear for usually the starboard engine in twin-screw boats and many ski boats too.

    NOTE: We also will have black 10.5mm spark plug wire sets (normal is 7mm) Oct.2020 permitting these wide plug gaps for possible increased power and fuel economy. They look awesome too!

    NOTE: Please allow two weeks before shipping as these are all built to order.
