EZ steer is for an I/O.

Re: Steer outboard from inboard tiller

How can I rig a cable to the tiller and OB?

Ayuh,... Why Cable it,... It's Hydrualic now... Add a cylinder to the Outboard...
In parallel with the right Sized cylinder, it should be Degree for Degree....

I asked the people at Seastar if I could do that with a Seastar splashwell mount outboard steering cylinder (HC5380) on the swim platform and teeing into the existing plumbing (Seastar 5271 helm, 5313 cylinder, Raymarine Type 1 pump). This is the answer I got:

Dennis: This will not work. The two cylinders are not the same in any way, this means that the whole steering of the boat will change. Teleflex doesn't have any recommendations in regards to this sort of set up.
I have seen customers install a solenoid valve to allow the helmsman to choose from one cylinder to another.
Basically you cannot run these two cylinders at the same time. You will need some sort of selector that will direct fluid from the helm to one cylinder at a time. Thanks and hope that this helps.

Ayuh,....
I never said life was Simple,+ Never even considered Buying something off the Shelf....

It's simple Hydrualics,... Pump oil in 1 end,+ it moves the other end a cubic amount...
It'll come down to the cubic volume of the cylinders...

Thanks for the info.

Thanks for the info.

I see what you are saying. So, if the steering cylinder (Seastar HC5313) has 8.3 cubic inches (135cc) of displacement, what size clyinder should the one for the outboard be?
Other info: helm - 5 turns lock to lock, 1.7 cubic inches (28cc) per revolution

Ayuh,... I'm a Mechanic,.... Not a Mathamagician....

The Helm's volume comes in to play as well,...
You want 3 to 5 turns lock to lock,... Not 15 or 20....

Don't know if it will work on an inboard but, I tightened the friction down on my kicker so it would not turn and steered my main outboard, like a rudder on a sailboat. It did not respond quickly, but worked for trolling.

Re: Steer outboard from inboard tiller

If you have an inboard that means you have a rudder for steering. why not center the kicker so it is locked straight and steer with your rudder?

Good point. The rudder will steer at WOT and when trolling in calm seas. But when we are fishing and it's windy it don't work very well. There just isn't enough water flowing on the rudder at trolling speeds. Got a lot of freeboard and the wind will turn the boat.

Re: Steer outboard from inboard tiller

Just throwing this out there it may be the dumbest idea ever.

1. Determine what size of hydraulic cylinder you need to turn your kicker lock to lock.

2. Mount the cylinder on the outside of the stern wall somehow.

3. Run a hydraulic line to the pump you use for main steering on the outlet of the pump.

4. Install a switching solenoid that directs fluid to only 1 cylinder at a time. Something like this:

http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200329549_200329549

5. I imagine this solenoid could be wired to be automatic. When the key is on and you have power to your main motor it switches to it. When no power to the motor it automatically switches to the kicker. Or you could just install a toggle to switch it.

6. May have to attach the cylinder shaft to the kicker with some type of snap in ball lock so that you can pop it off when you want to put your kicker up on the swin platform like I seen in your pics.

I now absolutley nothing about auto pilot systems but I would imagine if there is a switching solenoid it wouldn't know wheter it was turning the kicker or the rudder.


Edit: I just looked at your setup again. Is there room under the transom clamps to mount a cylinder there with some type of U-clamps? It would take some type of auxilary bar from the cylinder to the kicker. That would alleviate the need to unhook anything when you want to put your kicker up. Just have to make the line long enough to allow it to spin around.

Here is a drawing of what I am thinking, kinda looks like a kindergarten art project.

Re: Steer outboard from inboard tiller

You can't just hook 2 hydraulic cylinders in parallel. If you did, then with everything off, push the kicker one way and the rudder will go the other way. In series it might work, but you would basically need both cylinders to be identical or you would limit the travel of one or the other cylinder. Then you would have to mount and rig a linkage that would give the desired amount of steering on the kicker.

Re: Steer outboard from inboard tiller

Would they be considered in parallel if there is a electric control valve that switches from one cylinder to the other? I would think that with that valve one cylinder wouldn't know the other was there. But then again, I did say it might be a dumb idea (LOL). My experience with hydraulics is limited.

Nope,... That's not parallel,... That's 2 independent circuits...

The problem with that is the tiller sensor is on the tiller,...
The auto-pilot won't know which way the motor is pointed....

Ahh, I knew there had to be a catch in there some where.

Now you are on to something. :)
I tried to find more info on the www about "how to" series hydraulic cylinders but didn't come up with much. Help!

Re: Steer outboard from inboard tiller

what I do:
i got a some black abs pipe 3' long x 1 1/2'' (to match my Merc) and slipped it over the tiller handle, simple and it works! can be removed and while i'm fishing I use a bungy cord to hold the course. Works really well, and cost about $6 (I got a cap for the end)
