Glendinning Synchronizer users

[JohnEasley]

Will a Glendinning Synchronizer allow you to have both throttles at idle, engage the synchronizer, and control the throttles with just the master or must you advance the throttles before engaging the synchronizer? Ideally, I would like to set it up so the slave throttle does not have to be touched at all after leaving the dock. The master would control both through the entire range from idle on up. Can it be set up that way?

Thanks.

My manual says advance both throttles slightly above idle.
Engage sync.
Advance slave to full throttle.
Control rpm with master.

Manuals can be found on their web site

As bluebyu says you should advance the slave throttle once the solenoid is activated. The slave engine will follow whatever speed the lead engine sets. So yes the lead or master engine can control the revs. To work the engines in docking I always die gage and then use both engines traditionally as I find I need to have the revs set differently dependent upon the outside factors. The Glendinning Drive is a remarkable device and some of the best money I have spent.

As I am heading out of the marina I advance both throttles to 720 rpm. Then I turn on the Glendenning, push the slave throttle to full and control both engines with the master until I am back in a marina. It’s one of those devices that make you wonder how you ever boated with out it.

My GS (1976 version) won't engage until 8-900 rpm. Likewise, it drops out at about the same rpm coming down. Works like a champ. I want individual throttle control at low (idle) speed for maneuvering.

I never have advanced my slave to full - any idea why they suggest you do that? Can't imagine what would happen if you accidentally hit the sync button to turn it off.

 

[sbu22]

Nothing, actually. Until (at least on my setup) the slave is returned to fully to the low stop, that throttle is still slaved to the master. After hitting the low stop, the slave functions independently regardless of switch position. I had the same reservations. Test it at low rpm

i always wanted maximum control so never engaged the sync until i was away from the dock.

That explains it. Thanks.

When my slave is at a higher throttle than the master and I turn off the sync, the slave side throttles up. Now this is usually a hundred RPM or two, so not sure if there is a fail safe that stops it from doing that at a bigger gap.

If your sych drops out at low RPM you may have a low voltage problem. The solenoid won't stay engaged at low voltage. Check your batteries/alternator output.

I'm trouble shooting a Glendinning issue at this time. Call the plant. They have been immensely helpful. There are preset cutouts at low speed.

According to my manual you are supposed to advance both throttles just past idle (for me that is about 900-1000 RPM), engage synchronizer and then advance the slave all the way to the stop. I was not originally doing that, I engaged at idle, and I had an issue. Initially it worked as expected but after a bit the slave would start "hunting", meaning that it would speed up and then slow down. I re-read the section of the manual on operation and discovered the "advance both throttles past idle" part. Once I started doing that everything worked exactly as expected.

As to having to touch the slave throttle, once you engage the synchronizer and advance it to the stop you don't need to touch it again until you plan to disengage the synchronizer. The master throttle is the only one you need to move to control both engines.

I upgraded my Glendinnings at the start of last year, so 2017 models. I will have to get the manual out to see about this - mine work absolutely fine with the slave in whatever position I have it in when I turn on the sync.

Something else I do. When moving from the FB to the PH or vice versa, I CAN leave the throttles in gear as they were and set the throttles at the next station where I want them and then push the active button.

However I am never comfortable doing that. So I always put the station I am leaving into neutral, move to the next station and make sure that that station is in neutral and take control in neutral, before moving the throttles and resetting the sync.

I just feel more in control doing that.

Thanks, Marty. That’s what I was looking for.
