[C38] Shift Cable Legnth

Sun Mar 7 10:03:08 EST 2010

Steve,   Thanks, but I have found cables from 5" to 50', so the choices are 
almost infinate. Unless somoeone on the list has some more specific input, 
It looks like I'm going to need to throw in the snow shovel and dig my way 
to the boat.

I did ours last year I don't remember the size but do remember the choice 
was pretty easy the store had two sizes long and short I'm thinking the long 
was about 12 feet and it was the right one.   One thing I noticed on putting 
in the new one is that the old one was installed with the wrong angle to the 
shift lever on the transmission.  The directions in the box (telemorse I 
believe) showed the proper angle, that made a big difference on the ease of 
shifting.  The angle may also explain why it shifts on its own sometimes.

I also need a new shift cable. Can someone save me a trip to the boat and 
tell me what legnth cables to order?

Thanks Tom I will get under there in two weeks. I had new cables installed 
last year but it did not solve problem and the yard guys are just guessing 
at 90 bucks an hour. I can shift by hand down below even before the new 
cables. When I shift in reverse there is a slight hesitation I think it is 
that the lever on the transmission is not going all the way back. One other 
weird thing last week while backing I could not add any power, I know the 
cables are not connected but I could not add any RPM's, as soon as I got it 
in forward (very hard to shift) no problems. Also somtimes shifts by itself 
into forward that now makes sense if the cable is wrong not really all the 
way in neutral.

Thanks again will let you know how it turns out

Hi William,

The name of the discount parts house is Yacht Power Products at 727-822-2628 
in St. Petersburg Florida.

Having said that, you probably don't need a new transmission.  These Hurth 
transmissions are very reliable but they are also very sensitive to 
adjustment of the shift cable.  The cable bellcrank where the shift cable 
attaches has to be exactly neutral when the shifter at the binnacle is set 
to neutral or what you are experiencing can occur.

To adjust the cable, disconnect the cable to the bellcrank on the starboard 
side of the transmission accessed through the quarter berth.  Crank the 
engine at the dock and manually change through the F-N-R settings by 
reaching your hand to the bellcrank and twisting it.  If the transmission 
performs satisfactorily without the cable attached, you know your problem is 
the cable adjustment.

While the cable is still detached, look at the bellcrank and check that it 
is exactly perpendicular to the cable if the cable was still attached.  You 
may want to scratch a reference line across the end of the bellcrank shaft 
so you can "eyeball" the shaft to the bellcrank if you need to make 
adjustments.

I have also heard of having to loosen the four bolts that hold the bellcrank 
shaft to the transmission to adjust the shifting.  The slightest movement of 
that plate will also effect shifting.

If you are satisfied the problem is in the cable, have someone shift through 
the shifter range from the binnacle while you watch below to see if your 
cable is operating properly and the same distance for R and F.  If 
everything is adjusted properly,  manually check that the transmission is in 
neutral and then you should be able to put the binnacle lever in neutral and 
have the cable on the transmission slide right back into the hole on the 
bellcrank.  If you can't, adjust the cable until it does slide in easily.

While we are talking about these transmissions, if they hold in reverse or 
forward under load, even if you have to manually shift them as described 
above, and the transmission isn't leaking fluid, you have a good 
transmission.

One marvel about our transmissions is that the input shaft has spiral 
grooves attaching the driven plates of the clutch pack so that once the 
transmission is shifted from neutral, the torque of the engine tries to 
twist the spiral grooves of the input shaft making the plates bind very 
tight with very little cable pressure.  If you have driven a standard 
transmission car, you will remember that even a small car has a fairly hard 
clutch pedal pressure but our transmissions shift with only finger pressure 
because that spiral input shaft torques the clutch pack with incredible 
pressure.  Pretty smart idea but it also makes the shifter cable adjustments 
very critical.

I hope this helps.

Hi Tom Bill from Flying Goose. I thought I archived the discount name but I 
can't find it. Could you help me out? I think I need a new transmission. It 
will shift ok from reverse to neutral if it is not to warm. i.e. Just 
leaving the dock the engine will shift pretty good not great but if has run 
a n hour or so once in reverse will not shift back without shutting down 
engine. Any ideas ?
Thanks
Bill
