Chevy V8 Marine Certified Distributor Marine Ul-Certified MSD Ignition

Part #: 8560

Marine environments place rigorous demands on every component of the ignition system, especially the distributor. The combination of water spray, salt exposure, full throttle acceleration and harsh vibrations all take their toll.For marine use, the distributor cap is bolted to the aluminum base. There are two flame arrestor holes with brass screens machined into the base of the distributor to prevent ignition of gas fumes that may build up in the engine compartment. A special Weathertight Connector is supplied to provide a positive-lock and water resistant connection.The MSD Pro-Billet Distributor is the strongest and most accurate distributor you can put in your boat. The housing is CNC-machined from a billet of 6061-T6 aluminum creating a housing with no porosity. Internally, a QPQ coated shaft is guided by a sealed ball bearing and an extra long sintered bushing for highspeed stability. Each distributor uses MSD's race-proven magnetic pickup to trigger the ignition control. Mounted just above the pickup is a mechanical advance assembly that is easy to adjust so you can dial-in an ignition curve to match your boat's application (except PN 8366).The Marine Pro-Billet Distributors have been tested by Underwriter's Laboratory and are certified to meet or exceed safety standards for marine ignition systems as set by the U.S. Coast Guard.Easy-to-adjust mechanical advance with supplied springs and stop bushingsAdvance plate and weights are fine blanked from chrome moly steel and QPQ coated for friction reductionMust be used with an MSD Ignition ControlSpecial oil tract improves lubrication to the distributor and cam gearNylon pads ensure smooth operation of the advance weightsSupplied with a bolt down HEI style distributor cap and rotorMechanical advance assembly can be locked out for crank trigger systemsPolished steel shaft is QPQ coated and guided by a sealed ball bearing and extra long sintered bushingDesigned for use in marine applications with Chevy V8 automotive enginesO-ring seals can be added to modified blocks to improve oil pressure controlMaintenance-free magnetic pickup and precision reluctor create stable trigger signals throughout the rpm rangeWill not accept a vacuum advance canisterAdvance weight pins are staked and tig welded to the plateUL ApprovedWeathertight connectors are used for locked and sealed connectionsCNC machined billet aluminum housing and billet aluminum base with two flame arrestor holes with brass screensDetails:Distributor Cap Included: YesDistributor Type: Magnetic PickupEmission Code: 3Gear Material: Cast Iron Melonized QPQ CoatedIgnition Box Required: YesIgnition Coil Included: NoIgnition Rotor Included: YesWarranty: Manufacturer's Limited 1 Year Warranty
