Abstract
This invention relates to a modular mechanism and methods for synchronizing the speed of one engine with a reference speed such as another engine particularly as found in boats. A physically limited range of fine tuning is combined with the normal operation of existing manual control over its full range of course adjustment, without interference, by way of an adjustable link coupled non-resiliently in series with the throttle linkage and allowed to slide along a non-circular shaft or key that causes micrometer adjustments in length of the link between the manual control and the throttle when the key is turned. The key can be turned by a differential device or reversible motor responding to continuous or interruptable power related to the engine speeds. The device will not bind and need not be stopped from turning at or between its limits because both ends of the linkage cannot encounter opposing stops simultaneously, the link can slide longitudinally on the key, and the key rotates freely at the limits of adjustments. Phasing is also described.
