AccuSync Twin Engine Synchronizer


AccuSync™ controls twin engines accurately and effortlessly.
AccuSync™ fits All Outboards, Gas & Diesel I/O's and Inboard Engines
AccuSync™ provides smooth control at your fingertips.

AccuSync™ performs the job of synchronizing your mechanically controlled marine engines automatically when-ever you set the engine speed of both engines within approximately 15% or less of each other! AccuSync™ works continuously and effortlessly to synchronize your engines as you move both throttle levers to any selected speed from idle to wide open. A major benefit and convenience of AccuSync™ is that it gives you the freedom to operate each engine at different speeds whenever you need. AccuSync™ is very accurate, its digital control, controls smoothly at all speeds. No more steer-offs from the follower engine lagging behind the lead engine on accels and decels. The new AccuSync™ design eliminates all acceleration and deceleration problems of conventional synchronizers.
