Ryan,

Did you look up McMaster Carr? Do you use them.

I would first speak to Olivier before doing an in water boltectomy. I doubt that the bolt and sleeve are damaged. Are you headed back to Boston?

Thanks Eric, I appreciate your thoughts.  We're currently in Charleston, SC and tomorrow we're sailing to Southport, NC.

 

In looking at the diagram Bill posted, I'm wondering if the bushing has gone bad.  I'm already putting together an order from Amel, maybe I'll see if they have replacements.  Does anyone know the size of the bolt itself, so we can have a spare on hand before we go removing the existing one?

 

Thanks,

It looked exactly like yours. If you get to warm water you could dig the silicone out. Remove the bolt grease it and put it back with grease. Then crank it down tight.

I would ask Olivier, however I feel you could sail without silicone for a while.

Thank you all for the info.  I should have mentioned in my original post that we have a fixed propeller (I think its the original spare).  I'm a bit concerned about this domed mastic thing... depending on how you define "domed", it may have been in such a state when we last hauled out.  I've attached a photo.  What do you think?  We're no longer in the tropics, so it's too cold and too murky to go down and look at it now.

 

What purpose does the mastic serve?  Would it be harmful to remove it in the water and not replace it?  Presumably the rest of the bolt is exposed to seawater, so I don't see why the head needs special protection.

 

Thanks,

Hi Eric,

 

I'll see if I can get my hands on some Loctite 542.  I've never delved into their products beyond Blue and Red, and I don't think I want to use Red.

 

The screws are flat heads (countersunk).  The ones provided by Amel, which were lost overboard, were Allen drive, and our new ones are Phillips drive, but they're all the same head style.

The threads must be absolutely clean , I would clean the machine screws with lacquer thinner and also the internal threads. Did they use machine screws or allen head cap screws?

 

With respect to the prop shaft. There should be NO side to side movement of the shaft. Possibly he was speaking about the prop blades.

If they wobble you need to overhaul the prop, if it is an autoprop.

Hello again,

 

When we were in Le Marin, we had a bunch of work done on our genoa furler -- Amel rebuilt the gearbox, Caraibe Greement replaced the forestay, etc.  One of the things Amel did (unasked) was they drilled out the rivets connecting the gearbox to the furler extrusion and replaced them with machine screws.  Three times now we've had these screws fall out while under sail.  I emailed Alban at Amel Caraibe and he suggested using LocTite.  I've tried blue LocTite on them to no avail.  I'm considering installing a hose clamp around the outside so they physically cannot back out.  Has anyone else faced this issue and come up with a solution?

Hi Giovanni,

I do not have a photo because it is not visible. It is sealed with a black silicone sealant at the base of the C drive at the keel. It looks like a black silicone circle about 25-30 mm in diameter. The silicone should be flat. You can dive down and see it with a light it is quite visible.

If you notice that the mastic is domed and not flat where the c drive is fastened to the Keel then you definitely have to remove the mastic clean up the area and clean the bolt. Make sure to apply grease and use a torque wrench if you have one to torque the bolt down tight. If you are in the water you can inspect the mastic and if it is domed you have a problem., If it is flat that is not your problem.

There should be a stud/nut and possibly a bushing under that mastic on the bottom of the C-DRIVE. This stabilizes the C-DRIVE from any twisting due to thrust. Inspect it by removing the mastic.

Hi all,

 

In the last few days I've noticed a strange, intermittent vibration that seems to be coming from my propeller.

 

We had the engine mounts and Vetus coupling rubber balls replaced in Le Marin a few months ago, and this vibration does not feel similar to the one from when those needed replacement (and the mounts and coupling still look and feel fine).  This vibration is almost unnoticeable in the cockpit, but you can feel it when trying to sleep in the aft cabin, particularly in your legs (i.e. far aft).  It is rather intermittent, only lasting a few "thumps" at a time.  It seems to correlate when the boat is strongly rolling from one side to the other and often goes away when we're at a constant heel.  It happens more frequently at lower RPMs and it goes away completely at about 2000 RPM and above.  Our C-drive oil and transmission fluid look good.  A diver confirmed our propeller is clean, though he did ask me if the propeller pivots side to side when he came up.  I think he had noticed there is a bit of side to side play due to the rubber mount at the base of the C-drive housing connecting it to the keel.

 

Have any of you experienced something similar before?

 

Thanks,
