Yanmar Engine Kill cable

[smokey73]

1994 Hunter 40.5
The kill pull knob for my Yanmar 4JH2E is located just inside the companion way to the stbd side directly above the engine. To stop the diesel you pull up on the knob and it operates a lever to stop the engine. Pretty simple.

Does anyone have a source for a replacement. The inside cable (inside the sheath) has broken so to shut off the engine I need to open the engine access an manually operate the kill lever. I don't see it on the forum store.

Got my replacement at my Yanmar dealer for $87.12 back in 2020. You can also probabaly find it at an automotive shop as well.
Teleflex TFXTreme suitable to my mounting equipment in place at the time. Pull out your "entire" cable and all mounting hardware and take it with you.

I replaced mine at a Yanmar dealer. About the same price as @Ralph Johnstone paid, assuming he listed his price in Canadian Dollars. There is no replacing just the inner cable. They come in 2 lengths, I forget what those sizes were. The dealer had them in stock.

Any good marine parts dealer can replace it with a Teleflex aftermarket cable. Generically it’s called a morse cable, and many (most?) boats use them for throttle and gear shift controls. You can buy it in many lengths and you can even cut them to custom sizes.

On a Yanmar the shut down cable is a thin wire inside a cover with a bare end with the other end having a fitting that goes into the engine control panel and a knob attached to a short bar and the cable. It is very different from a Morse or Teleflex cable used for throttle and transmissions. With that said, it would be possible to used a Teleflex cable with modifications to the whole system.

Replaced my original (1985) Yanmar this year. Since I'd worked as a bicycle mechanic, I recognized the cable as bicycle shift cable. I could not find a way to easily fix it so I did pay the outrageous Yanmar price. A choke cable from auto parts would work with a little improv, but I figured that the original had lasted quite well and I would go with a Yanmar part.

Thanks, I'll pull the old cable and get the length. I'm seeing cables that use "clamps" and those that have threaded fittings. I'd like to keep the same mounting like Ralph was able to do so I think I'll need the kind with threaded fittings at both ends. I'd like a stainless steel wire kind. Once I get it out I'll check online or at a Yanmar supplier. Thanks.

There are two clamps as I recall. One in the bunkhead and the other near the transmission linkage. I’m assuming all 40.5s were built with that same cable configuration.

Don, the 40.5 is a little different. The pull knob is located just inside the cabin at the top of the steps inside the companionway and is fixed at both ends with threaded fittings rather than clamps but I can probably convert to clamps but I'd like to keep the same threaded connections if possible.

How could you forget the two sizes ?
It's either a) too long or b) too short.

One last word on this ................... the knob end has a gland (if you will) which consists of the tiniest little "O" ring you've ever seen. Apply a non-petroleum grease to this every other year and it will last forever, possibly even longer.

I‘m confused. I was talking about my 40.5 configuration as you were asking specifically about that model.

@Don S/V ILLusion Sorry, I didn't understand "bunkhead" (think its Bulkhead) and I since I saw Alden 50 I was assuming you meant that boat. My Bad

my proofreading skill is lacking (I.e. bunkhead).
Our previous boat was a 40.5 on which I had to replace that cable.

I called Mack Boring and he gave me the part numbers for the 400mm and 500mm cables so I'll find a Yanmar retailer nearby and see if I can pick one up. I'll look on the site here too.

Reading the earlier posts, it seems that Hunter used a different cable system than the stock Yanmar cable. The Yanmar cable is nothing special except for the fitting at the instrument panel. Sounds like Hunter might have found a less expensive system.

 

[smokey73]

Just checked my numbers? 400 mm is only 1.3 ft and that is not nearly long enough. I'll have to check again

I think it is 4 meters not 400 mm, 4000 mm would be 4 meters.

Can you post a picture of the cable ends?

 

[smokey73]

Can't post a picture right now. I'll be out to the boat tomorrow I hope.
