Editor's Notes

July 31, 2019:

Distributor ignition systems require the periodic replacement of the cap and rotor components because of mechanical wear and because the constant arcing across the cap contacts and the rotor eventually oxidize them. These type of systems are considered mechanically controlled because they are directly connected to the camshaft and timing systems in the engine. They have now been nearly universally replaced by electronic ignition systems like the popular coil-on-plug system. Electronic ignitions are much more efficient, require less maintenance, and eliminate mechanical wear in the ignition process.

Distributors are nevertheless common in older model automobiles and particularly, in marine engines. This is why we included the Quicksilver 805759Q3 which has design features that allow it to perform in the hazardous conditions that marine engines are exposed to. For performance enhancements to mechanically controlled ignitions, the Mallory 208M and the MSD 8482 can be used in conjunction with high-output distributors and camshafts to yield sizable gains.

All auto repair and modification is dangerous and should only be performed by trained technicians to avoid personal injury or damage to equipment.
