Abstract
A shift cable assembly for a marine drive having a clutch and gear assembly (18), includes a remote control (11) for selectively positioning the clutch and gear assembly into forward, neutral and reverse, a control cable (10) connecting the remote control to a shift lever (3) pivotally mounted on a shift plate (2), a drive cable (17) connecting the shift lever on the shift plate to the clutch and gear assembly, and a spring guide assembly (100) with compression springs (101, 102, 103) biased to a loaded condition by movement of the remote control from neutral to forward and also biased to a loaded condition by movement of the remote control from neutral to reverse. The bias minimizes chatter of the clutch and gear assembly upon shifting into gear, and aids shifting out of gear and minimizes slow shifting out of gear and returns the remote control to neutral, all with minimum backlash of the cables. The spring guide assembly includes an outer tube (106) mounted to the shift plate, and a spring biased plunger (107) axially reciprocal in the outer tube and mounted at its outer end (10a) to the shift lever.
