Goiot control housing

[ithet]

My Beneteau 331 single lever control has lost its throttle ability. The cable is OK at the engine end, so is either broken or detached at the control. Either way I need to get to the control end of the cable. Unfortunately the stainless screws that hold the two halves of the alloy housing unit have seized. They are also awkward to drill out as they face into the pedestal. Does anyone know if the unit will rotate (under force) to re-orientate the screws? Alternatively can I remove the whole assembly with the tube along with the cable?

Its a Goiot unit, similar to many Beneteau and Jeanneau.

Get a set like this https://www.ebay.co.uk/itm/BERGEN-T...406153&hash=item3ae9fa74f8:g:nAkAAOSwSP5ZX7kj as ordinary Allen keys are unlikely to shift the screws. Use a half inch drive tee handle from a socket set to work the Allen screws back and forth to loosen them. The worst that can happen is that you shear some of them off. If that happens soak the alloy casting with the broken screws in it in hot water until you can twist them out with mole grips.

P.S When you re-assemble use new Stainless screws, and put them in with Duralac smeared on them.

Yup, tried those. Can't get the socket to all the cap screws and only one has freed. On another one has damaged the head.

The one with the damaged head needs drilling out, but that is fairly easy with screws like that if you have a low speed drill. If the screws are 6mm, use a sharp 6mm drill with slow speed and a lot of pressure until it takes the head off the screw. Cutting lubricant in paste form, like Trefolex or Rotol RTD helps. I suggest using a 5mm drill first to deepen the socket in the screw head by about 2-3 mm. If you can't shift the rest with hex bits and a tee handle you are probably going to have to drill them as well. The vital thing when drilling is not to allow the drill to rub as the as stainless work hardens and makes further drilling very hard. I have dealt with a stainless screw on one occasion using a big hand "gut-buster" drill as it was the only thing I had that was slow enough and strong enough to apply the pressure needed. I put a ratchet strap right round the part with the screw in it and the pressure plate on the back of the drill and tensioned the ratchet.

I think most of the screws will need drilling out, thanks for the detailed info. The problem is the screws are not easily accessible to work on, as they are on the wrong side of the unit and obstructed. That it why I am asking if there is any knowledge here as to how to turn the unit around or if it is possible to remove to get better access.

I found some pictures of an open one (to refresh my memory) here http://jeanneau.proboards.com/thread/3252/throttle-handle-removal-adjustment

It doesn't look like there's anything positively stopping it rotating at the top end, not so sure about the bottom.

Sooner or later you're going to have to disassemble the white Goiot teardrop to change a broken throttle or gear cable or fix a broken component on the inner Teleflex mechanism. Might as well do it now. On my Jeanneau with a similar setup the only thing holding the teardrop onto the vertical tube is friction from the black collars at top and bottom with tightly fastened screws on the white bit. Once screws loosened slightly it will rotate a bit, but not fully - enough to improve access to other screws.

The day your gearchange or throttle cable snaps you'll want to get it off again, so reassemble with new screws and some grease on threads.

I shall try and rotate the unit on the friction collars to get to the cap screws better - that was the information I needed, thanks. Have only managed to loosen one screw so far though. Yes they will be new screws and Duralac.

The day is now! The throttle cable is broken or disconnected.

We are having trouble with this unit. But it is that the splines are worn on the handle and on the throttle/shift control that sticks out from the housing. So there is no purchase. Anyone have any idea if replacement parts are available for this unit? Or where we may purchase them? We are in the US Virgin Islands. Thanks!
