Help with remote control for 1975 evinrude 25

[ColinSwartz]

I have a 1975 Evinrude 25 Model Number 25503B and I was wondering if there is any way that I could convert it from a tiller to remote control? I just recently bought a boat that already has a steering wheel so I can connect the steering using a transom bracket if you could give any recommendations that would be great. Thanks.

Of course you can. The shift & throttle control is a piece of cake. Steering? Well it sort of depends on what kind of steering system is in the boat. Best & easiest is the old cable & pulleys system that it was designed for. But more than likely you have a push-pull cable, right? Yes with the proper parts, you can hook it up and it will work, but with compromise. That would be loss of steering arc and interference with tilting. There are a few attaching devices to pick from.

Colin Swartz, :welcome: to iboats. Nice to have you aboard...

You can change a tiller to a remote. But a few things will have to be bought and setup and maybe some things modified to work properly and safely. I am assuming your OB engine does not have the standard tilt tube setup. I am assuming that because I own a 1976 40HP Johnson engine and it doesn't have the tilt tube design. However, I am setting up a stick steering hull and they make a tilt tube adapter for stick steering setups. But the adapter won't work for a starboard steering setup but only a port setup for the steering cable inlet. So if you are going to go steering wheel, you are going to have to either come in from the port side, or go cable and pulleys.

As for the remote controls, you can use one of the older Sea Horse control units. I completely refurbish such a remote unit and it is perfect for what you would need as well.

This is a old Sea Horse remote control and will work with your engine. So look on EBay or wherever and see what is available. And parts are still available for these older control units yet too. JMHO!

Nice job rehabbing the box, gm.

ColinS. -- Might post some pictures of steering. There are options. Also, might check Ebay for a '75 manual on accessories (see what the original components were).

I have a push pull cable, what parts would i need to hook this up to the motor, i know i need the transom bracket but how will the steering connect to the engine?

Colin, your engine has a part called a steering bracket. Of course that part is obsolete but I'm assuming yours is well and good. There is a hole in the center of that steering bracket and that is where you will attack your steering setup regardless which type you chose.


Now all you have to do is research how to set up the cable and pulley setup. Hope this helps a little.

No Title

First thing you need to do is evaluate what you have. Picture??? How long is the push-pull cable? long enough that it extends across the front of the motor? If it is, it is sized for a tilt-tube system. Sure, you can pull it back a foot and use a transom bracket, but all that extra length has to go somewhere. In other words, extra bends in the cable. That will make it steer like a dump truck. Hopefully, it only extends to the center of the motor. In that case, you are good to go with a transom bracket. To connect it to the motor, use a standard OMC tiller attachment like this one (without the links). Then connect the push-pull cable to that with a Teleflex clevis kit.

Another option you may consider is a T&R kit that puts the tube below the motor, if you have the long cable. Google trmarine
