Abstract
An improved fuel injection and ignition control system for an engine, wherein the fuel injectors and ignition are controlled by respective circuits mounted on a common substrate but spaced from each other. The assembly is potted in a resin for electrical and heat insulation. The resulting control box can easily be mounted in the valley of a V-type engine in the powerhead of an outboard motor.
