MSD 83607 Distributors MSD's Ready-to-Run Marine Distributors are the perfect upgrade for boats that are relying on worn-out breaker points or weak ignition systems. Built off our tried and true billet marine distributors, the 6061-T6 aluminum housing is now hard anodized with a sleek black finish for great looks. This module produces a stout inductive spark that will improve combustion of the fuel mixture for better drivability.  Beneath the durable bolt-down, injection-molded cap, a maintenance-free magnetic pickup produces accurate trigger signals while an oversized shaft is guided by a sealed ball bearing. An easy-to-adjust mechanical advance allows you to custom-tailor a timing curve to match your application. The Ready-to-Run distributors are a breeze to install. Simply drop it into the engine and connect three wires, and you're ready-to-run across the lake! Supplied with a cap, rotor, gear, and weathertight wiring harness. Features: Black anodized for great looks and corrosion resistance Only three wires to connect for a simple installation High output ignition module produces quick starts, smooth idle, and improved mid-range performance Accurate and maintenance-free magnetic pick-up never needs adjustment Easily adjust the mechanical advance with the supplied springs and stop bushings to fit your boat’s needs Now includes built-in rev limiter Normalized SKU: 83607UPC Code: 085132836079

MSD 8226 Ignition Coils Top off your GM Ignition system with these great new replacement coils. The GM Coils have MSD performance in factory-style housings! MSD designed these Coils by combining our Blaster Coil experience with E-core coil efficiency. Each coil has a unique turns ratio, plus there is lower primary resistance than the stock coil. This all amounts to a bolt-in replacement coil that produces more output voltage. The Coils will work with stock ignition systems as well as MSD-equipped cars and trucks. The MSD Blaster GM Coil is designed to produce increased voltage and energy over the stock GM Coil. To get even more ignition performance, install an MSD Ignition Control with a PN 8876 Harness for a direct plug-in installation. Features: Direct performance replacement for the GM dual connector coil 100:1 turns ratio and lower primary resistance produce high voltage output Works with stock ignition as well as MSD Ignitions CARB E.O.

MSD 83663 Distributors GM late-model performance enthusiasts will be happy to see this Pro-Billet Distributor. The distributor, PN 83663, is a drop-in replacement for GM V8s using the small cap distributor with a dual connector coil found in cars from 1987-1993 and trucks from 1987-1995. The entire housing is CNC-machined to exact tolerances for incredible strength (not to mention cool looks). For improved lubrication, there is an extra oil tract machined into the bottom of the housing that delivers oil directly to the cam and distributor gears. Inside, a polished steel shaft receives guidance from a sealed ball bearing, and an extra-long sintered bushing adds stability. This 0.500" shaft also receives a QPQ coating for increased friction reduction and corrosion resistance. A factory-style ignition module is supplied with the distributor, so your factory wiring will plug directly in. Triggering this module is the responsibility of a high-output magnetic pick-up. Topping it all off is a heavy-duty rotor and a red MSD cap with brass terminals to ensure full spark delivery. For late-model engine swaps or bolt-on strength, this distributor is the answer. Features: Drop-in billet replacement for GM distributors with the small cap and external coil Factory-style ignition module accepts factory wiring CNC-machined billet aluminum housing and billet aluminum base Magnetic pickup and precision reluctor create stable trigger signals throughout the rpm range Oversized steel shaft is QPQ coated and guided by a sealed ball bearing and an extra-long sintered bushing Special oil tract improves lubrication to the distributor and cam gear O-ring seals can be added to modified blocks to improve oil pressure control Supplied with a late-model distributor cap and rotor Legal to install in all 50 states Marine UL Certified Normalized SKU: 83663UPC Code: 085132836635

MSD 8876 Wiring Harness The harnesses plug directly into your factory coil and harness, then four color-coded wires plug into the corresponding wires of the MSD. Normalized SKU: 8876UPC Code: 085132088768
