I just recently bought a 1983 aero-glass phantom 15' bass boat that has a 1988 70 horse evinrude. I am not new to boating,i have been around it all my life but this is my first time dealing with steering systems. The steering is very stiff, it takes 2 hands to turn the wheel and i was wondering if anyone could tell me if theres anyway to lube it or something to help loosen it up?

I am new to the site, looks like it is filled with good helpful info and look forward to using it as a reference to future questions i have!

Re: Steering question on a 70 evinrude

Three step diagnosis:
1. Disconnect the steering Link arm from the end of the steering cable at the motor.
Try to turn the motor back and forth, if it moves freely, then the problem lies in the rest of the steering, if it moves stiffly, then the main tube the motor pivots on will need to be lubed and worked loose.
2. Try to turn the steering with the cable still in the tilt tube of the motor (but not attached to the motor). If it is stiff to turn it is either a bad cable, or the cable is seized in the tilt tube.
3. Remove the steering cable from the tilt tube (steering tube), (you may have to pull the motor depending on the clearance) and see if it moves freely with the steering wheel. If it is still stiff, its a bad cable, and needs to be replaced (can't really lube them).
If it moves freely out of the tube, the tube will need to be reamed out, greased and the cable put back in.

About to leave work, but I will try to give you more details when I get back on later. thats at least something to start with.

Re: Steering question on a 70 evinrude

OK here we go:

Step 1: - Disconnecting the link arm from the steering cable

End of the steering cable where the steering link arm attaches:

Plus a little closer view:

Undo the lock-nut (should be a 9/16), and take out the steering arm... try to pivot the motor back and forth with the link arm disconnected, it should move easily and freely... (if it binds then let me know, but this is not very commmon).

Step 2 checking the steering cable part 1

Spot where steering cable connects to the motor through the tilt tube:

and a little closer view:

Motor003.jpg


Disconnect the large nut (should be 1-1/8" if I remember correctly).
With the nut disconnected try to turn the steering wheel so the cable starts to come out of the tube.... one of two things will happen, either the entire cable (and sleeve) will move, or just the inner portion of the cable will move. If just the inner portion of the cable moves, and it moves easily, then what's happening is the main steering end of the cable is "sticking" in the tilt tube... this is quite common on engines where the cable isnt greased regularly.

This is where it gets fun..... to take the cable up, turn the steering wheel until the big nut is back at the end of the tube, making the whole assembly as short as possible... then you will have to get the cable out of the tube by pushing it out at the opposite end (the end where you disconnected the link arm). The only problem here is, many, many boats are set-up where you won't have enough clearance to push the cable assembly back into the boat, and have enough room to take the cable out of the tilt tube... if thats the case, then you are looking at pulling the motor (not all the way), but at least unbolting it, and moving it to the left so you can get clearance to get the cable out.

You can double check the cable at this point and see if it is still "stiff" to turn, if it is, then you will have to replace it. (it's not very common, but the stiffness can also be in the helm, but this is rare).

Once the cable is out, you have to "reem" the tilt tube out.

Picture of empty tilt tube here: (disregard the fact that the nuts are off, I was changing out a bad one)

Port side of motor:

Starboard side of motor:

You need to put the reeming tool, (they sell them here at iboats: Clicky ,on the end of a drill, and put some penetrating oil on it, and work it back and forth through the tube to clean it out... this removes old grease/corrosion/rust build-up.

reverse the procedure to install the new cable.

(NOTE: This does not include directions for completely changing the cable, there is additional work to do at the helm to change out a cable, and is a little different for a rotary helm versus a rack&pinion helm).

If you get to the point where you think you might need to change out the whole cable, let me know, and I will see what I can do to get you some more info, but the instructions for that part come with the steering cable replacement.

Hope that helps!

(sorry I couldnt edit the pictures with some arrows to point the stuff out, but hopefully you can figure it out).

If you have any questions, please let me know.

Re: Steering question on a 70 evinrude

Thank you very much Num, those were great instructions. Ok so i have eliminated down one of them, i disconnected the motor from the cable and it turns freely and smoothly. So then i proceeded to loosing the nut on the cable and i don't have a big enough wrench to do the job and i dont have a 2nd pair of channel locks to hold the trim tube nut while i loosen the cable nut. I hate not having the right tools for a job:mad:. But im going to go to the shop i work at in a bit and borrow the tools i need. Oh and a little good news is i think i will have plenty of room to get the cable out of the tub without moving the motor over, gotta love bass boats!
