Yanmar throttle reversed

[kenyon]

My boat was re-powered by the previous owner with a nice new Yanmar, but they chose not to deal with the issue of the reversed throttle operation.  I would like to figure out how to get it changed to normal operation to avoid confusion.  I have looked at the pedestal end and there doesn't seem to be a way to reverse it there.  So, it looks like there would need to be some type of lever that changes the throttle movement from pull to push operation.  Has anyone run into this issue and found a solution?  Michael or Bill?

I had a similar issue.

After talking a bunch of crazy solutions at my local "Kick-Me" boat
yard, I had them create an extension bar that extended in the OPPOSITE
direction, across the axis, from the throttle lever. Attach the cable to
that end, and the action is reversed.

This is an opportunity to change how far the throttle moves with each
bit of lever advance.

It may depend on what pedestal you have. On WW & Cayenne, the pedestal is
Merriman. The throttle linkage inside the pedestal can be disconnected from
the throttle cable, then the linkage that is clamped onto the throttle shaft
can be loosened and rotated 180n degrees, then retightened. Then reattach
the throttle cable to the linkage arm and it's done.
Having described this, I must confess that I always have intended to do
this. It's on my bucket list, but not done yet Now that I've been using it
"backwards" for 12 years, I like it the way it is!

The first thing I did on Pelican was replace the dual throttle controls with the Edson single lever engine control.  I can keep a hand on the wheel while doing back and fills with the engine.  Let me tell you how helpful this is in a 30kt+ cross wind in a tight fairway and you miss your slip!  Probably the single best change we did on our boat.

Hi Chris,

Can you give us more details on the process for switching over?  Where did you mount the single control?  Did you have an Edison binnacle or the Merriman?  Did you also have the reverse throttle problem when you switch to the single control, and if so, were you able to solve it?

Thanks!

We hired a company in Annapolis to do the work for us as we weren't near Pelican between when we bought her and when we had to bring her north from Annapolis.

This is what we installed - http://bit.ly/14UkYSZ

It may account for the reverse throttle issue in its installation, or this problem was dealt with when Pelican was repowered (I was never told there were any issues installing the controls).  We have the Merriman binnacle with stainless tubing around it.  The engine control was able to be mounted to the tubing and reach the cables in the binnacle (I'll try to remember to take a picture this weekend).  Unfortunately, we had to remove the wheel lock in order to install the controls so now I have to tie my wheel with line when I'm not there.  Regardless, not having separate controls for gear select vs. throttle is wonderful.  I can't even imagine going back.

I think this is the best way for me to go long term.  I was going to make major modifications to our Yacht Specialties/Merriman pedestal when we do new electronics in the next couple of years anyway.  I just wasn't sure whether it would fix the reversed throttle or that would still be an issue.  Calling Edson about it was on my list of things to do this week.  The makers of NavPod are coming out with a replacement top plate for the YS pedestal that will take a 12" wide 1.25" tubing guard which is the diameter that the Edson single lever system needs to run the cables through.  The plate will be stainless, but is still in development without pricing available, so calling them was on my list as well.  I will try to see if I can implement Bill's fix in the mean time.

I talked with Edson and they confirmed that the single throttle lever control can be configured to be either push or pull, so no modification at the engine connection is required.  While obviously not the cheapest solution at around $1100, is a compelling one for the convenience.

Changing throttle direction is really a pretty simple process.  You need about a six inch long plate to clamp the cable and mount a pivot arm to.  Throttle cable attaches to one side of the arm, throttle linkage to the other.  You can buy throttle linkages off the shelf that accommodate this.   I replaced my Yacht Specialties pedestal last year with a used Edson Pedestal that I rebuilt.  The YS controls were push to accelerate and the Edson is pull to accelerate.  In my case, I removed the pivot arm and remounted the cable clamp.  A good diesel shop might even have used control arms that could be used.  Attached is an old prepurchase photo of the throttle linkage on Perla.  Ugly photo, but I think you can make out the linkage.
