Built for boats running on worn breaker points or tired ignition systems, the MSD Chevy V8 Marine Ready-to-Run distributor houses a powerful ignition module directly in its billet aluminum housing for a strong inductive spark and better combustion. Beneath the durable, bolt-down, injection-molded cap, a maintenance-free magnetic pickup delivers accurate trigger signals while an oversized shaft rides in a sealed ball bearing. The mechanical advance is easy to adjust with the supplied springs and stop bushings, and installation only requires connecting three wires — a cap, rotor, gear, and weathertight wiring harness are all included.
