IF PERFORMANCE, FUEL ECONOMY AND RELIABILITY IS IMPORTANT TO YOU, READ ON. Built for marine only. All new for 2020. Included is our 65000 volt coil and matching electronic performance module. (stock is about 18000 volts when new) Fits 5.0, 5.7, 7.4 and 8.2 Chev marine based engines such as MerCruiser, OMC, Volvo Penta, Pleasurecraft, most ChrisCraft, Yanmar and others. Re-gap your spark plugs to .060 and feel the efficiency gained, up to 55 HP. No boxes, coils or anything else needed. (or wanted) Our motto since 1959, "Engines Love Us". email@example.com or call 1-877-253-7882 toll-free with any questions or phone orders if you prefer rather than online. Subject to stock on hand.
Step up to the proven best. Your engine needs this. Improves your power and economy through greater engine volumetric efficiency, completely burning your fuel/air mixture. No more black streaks in the water behind your boat when trolling or running slow. Professionally designed with no vacuum advance for marine use. Vacuum advance is locked internally, and centrifugal advance is suited for marine usage. Fitted with a screened 1/2" hole in the base for venting and no vents in cap per USCG and SAE J1171 rulings for marine use. Troublesome multi-spark boxes not recommended as they are ineffective at cruising RPMs anyway, and decrease dependability as just another thing to go wrong.
Matching red giant spiral core 10.5mm spark plug wires (stock is usually 7mm) with watertight boots now included, which allows the full energy potential to deliver the entire spark from our specially designed high performance coil and electronic module in the distributor to your spark plugs. NOT AVAILABLE ELSEWHERE. The 2nd photo shows the diameter difference of stock wire and ours.
NOTE: This distributor measures 5" diameter rather than the common 4", so make sure you have the additional room. (99% do)
Complete instructions included of course, and how to hook up your Alpha 1 or Cobra shift interrupter switch if so equipped.
NOTE: If you are using an automotive distributor rather than marine and you forget your drain plug or whatever, your insurance is worthless, let alone USCG inspections and safety from fire and your boat being confiscated by inspectors.
NOTE: If you need a matching reverse rotation distributor gear for the starboard engine or for some ski boats, we have it for only 69.97!
NOTE: Unless you already have the power plug from a previous HEI installation, you may order it under related items (showing up during checkout)
NOTE: OUR MARINE DISTRIBUTORS ARE NOT AVAILABLE ELSEWHERE! We don't sell cleats or flowers as competitors do, as we are 100% marine engine parts.
