Ensure precise ignition timing and peak engine performance with this New 4-Cylinder Timer Base manufactured by CDI Electronics. This professional-grade aftermarket component is specifically designed for Johnson and Evinrude 85 HP to 140 HP V4 models produced between 1973 and 1978. It is engineered for systems utilizing the screw-terminal style power pack.
The timer base plays a critical role in your outboard's electrical system by communicating the exact position of the crankshaft to the power pack. Exposure to high-vibration marine environments and heat cycles can cause internal sensor failure, resulting in hard starting, poor acceleration, or a complete loss of spark on multiple cylinders. This CDI Electronics unit is built to meet or exceed original factory specifications, offering a reliable, modern replacement for aging vintage ignition components.
