I have a Yanmar 2GM20F with a Kanzaki transmission. . . the shifting is real hard, I've determined it's the cable - when I disconnect the cable from the transmission i can shift (at the transmission) very easily. . . questions - the cable is in a tube from the shift lever on the pedestal to the transmission, is the tube part of the cable? can I pull the cable out and leave the tube in place? is there a way to lubricate the cable in place? any advice on this problem will be greatly appreciated. . . thanks, Pat

Lubing cable

If the top of the cable is fairly easy to get to, go to a motorcycle shop and get you a cable luber thingy. They are made to go around the top of the cable, and force oil in. Make sure there aren't any kinks, or places where the housing is rubbed through. If you find a kink or a bad spot in the housing, then you need to replace it. Do not try to replace just the inner cable. The cables are available from most marine supply places, such as West, and are not extremely difficult to replace. You just need to do a good Spiderman impression and it's a snap.

Plan B: just replace the cable with new

Some cables can get gummy over time. I tried the lube route with a fairly potent cable grease by something like Kable Ease but it only helped somewhat. Applying it was difficult because the cable wire was "down in there" inside the pedestal and hard to get at.

Wound up using a length of tie-wire and running the lubricant down the tie wire and touching the cable wire, then working the lever back and fourth. Lots of work for very little gain.

My pedestal is an Edson model and they have instructions for how to replace the throttle and shift cables on-line.

My notes for the H-35 Push-Pull Control Cables
The cable is a Teleflex CC17216 [which is 16-ft long] and has “A1151” on both ends, for both the shift and the throttle. On the 35.5 the shift cable is 14 feet which would probably be better on the Legend 35 also.

It was a bit of a chore replacing the cable, a job taking at least a couple hours, but in the end it was well worth it. The shifter can be operated with one's little pinky now!

The problem with continuing to use a very difficult to shift cable is the set screw for the shifter can shear off over time; the shift lever can break if it's plastic; it puts wear on the shift lever bearing, and the cable can break.

Which brings up a near accident: a Boat was pulling up to the dock behind a large and expensive power boat and the guy's wife was at the helm. He threw me the dock line and fortunately they were going fairly slow. When she went to put it into reverse the lever broke!

Fortunately, I was able to snag a cleat and prevent the bow from ramming the stern of the power boat so it was really lucky. The sailboat was about a 40-footer so there was a lot of mass to slow down and stop in a very short distance. The shift mechanism on their boat was a Volvo one, one of those all-in-one types. Stuff can happen.

I haven't had good luck with cables when it comes to binding. I once spent hours upon hours trying to loosen a steering cable (push/pull) for a Yacht Specialties helm on a small boat, and though I got it to work much better, it wasn't very good in the grand scheme of things.

Over time, besides the lube drying out and dirt getting in, the strands can break, causing fish hooks and other binding or high friction issues.

For a throttle or shifter, I wouldn't even mess around. And as the post above pointed out, shifting problems are at their worst when you really need to get in or out of gear, as I found out when I first docked my new-to-me trailer sailboat with a shifter neutral-only high-idle lever interlock (Honda O/B) that comes in when it's not supposed to. :eek:

I think I dodged a bullet with this one, when I disconnected the cable from the shifter assembly (on the pedestal) I found the shifter to be the problem - bound up pretty tight... does anyone know how the shifter is put together? I looked on the Edson website, but no detail on controls... I had no luck taking it apart, I was able to free the mechanism up with heat, Gunk lube and patience, but sooner or later it's gotta be stripped and cleaned... both set screws, holding the shifter handle and half-way point of the shifter "cylinder" itself, I have not been able to loosen... the shifter is just the cylinder in the pedestal, what allows it to turn freely and stay in place?
