*We syncronize our engines the 100% reliable*way, which is by ear and feel. Never had a problem getting them in sync at any rpm using this method.* The SW tachs on our boat offer "suggestions" as to actual rpm.* They're close, but not close enough to use for syncing the engines.* We've adjusted them a few times using a*strobe*timer on the drive pulleys on the fronts of the engines but the tachs drift off again almost immediately.KJ wrote:

*John, with Accusync you still operate both throttle levers.* For the sync to work, the engines have to be within 15% of the same speed.* Then it brings them into sync.* You can still accellerate or deellerate an engine by bringing it out of the 15% window.* The flick of a switch turns it off completely.* I do not have it on in a harbor as I tend to steer with the throttles and gears in tight places.* Works for me. YMMV.Baker wrote:
I am with Marin on this one. Another thing that always made me feel kinda weird was the synchronizers that only use one power lever after you get them synced up.....that is just not natural. I have run on some big sportfishes with BIG engines from the flybridge and you just don't get the "tactile" feedback necessary to sync by ear/feel(like doing 25kts at 1700RPMs...wind and water noises dominate). So I imagine synchros on those boats to be necessary....or not.
If you get right down to it, why synch them??? To get rid of that annoying wahwahwahwah.....and if you can't hear or feel it, who cares????!!!!...

Synchronizers are installed purely for comfort. There may be nano-benefits in increased efficiency related to load sharing but it is probably too small to measure.psneeld wrote:...but reduction in wear from harmonic vibration is the real reason to sync I believe.
