Re: [Amel Yacht Owners] Rudder shaft leak.

Jean-Pierre Germain <jgermain@...>

Hi Kent and Eric,

We changed the packing in July. Been dry almost always. 

One difficulty I have is the modified rudder bellcrank needed to accommodate the hyd AP DRIVE. Means I must place the boat in irons to dismantle the array. I outwaited the leak and fixed the issue in 30 mins once at the dock. 

Comment on the hyd AP: works very well and is far more supple than the elec unit. If you ever consider such a mod, I am very pleased.

Hi Kent,

As long as the nylon nut is not bottomed out you can just tighten  the nut  an 1/8th of a turn and all is well with the world.

If the nut is almost bottomed out I would replace the packing.

I would get the packing from Amel as it is cut perfectly.


I have a spare nut and a set of packing duct taped near the rudder post.

Worst case scenario you can change the packing while under way. You can definitely change the top 2 pieces and depending how low the stern is sitting possibly change all 3.

It is a pill to remove the packing. I use a narrow screwdriver to chisel the packing out.


Plan on having it leaking for a while until the packing becomes seated and absorbs a little water. I use molycote grease on the packing. I also had a wrench made that I use to tighten the nut while under way.

It was cut out of a piece of aluminum as thick as the flange of the nut and is short enough to turn without hitting any stringers.

Hi JP, and Merry Christmas one and all.


I've had Kristy 8 + years and only developed a small leak last year.  I tightened the nut a bit and have had no further leaks in the last year.  I have never tightened that nut except the one time it was leaking.  Same packing as when I bought her.  I've put nearly 20,000 nm under the keel in all kinds of seas.

Am I just lucky?


Before I do an ocean crossing I guess I'll replace the packing, or should I wait til it leaks and won't stop with a tweak of the nut?

Hello Steve,


Thanks for the info.  We did quite a few miles from Majorca to 4 days out of Lanzarote…  about 2000 + I reckon…


I will include the big Nut in my 6 month maintenance.


Merry Xmas too.  Just off to celebrate with a dozen other friends … too much wine on hand; this will be painful :-)

Hi JP,


Congratulations on a successful passage, and Merry Christmas. 


Our rudder post tends to develop a small leak about once a year, and about an eighth of a turn on the nut will stop it. We have new packing, but have not changed it since we bought the boat in 2014.

Merry Christmas Gang,


We arrived in Guadeloupe from Lanzarote. 7 days of slow slogging then 11 days of good progress.  Total 18 days 20 hours.  


Our beauty held up fine and we only have a rail cleat to repair and a rudder post leak to stop... the latter is done already but the question is this: we changed the rudder packing in July and twice tightened the big nylon nut.  Worked sans leak from Majorca to Gib, Madeira and Lanzarote.  4 days out of Lanzarote, a small leak began... then got worse as we sailed west.  Nothing alarming but needing a drying up session every 2 hours at the end.  Do you do preventive "tightening" ... if so at how many miles?  


Sea states were 5-6 and occasionally 7.  The hydraulic AP worked flawlessly throughout.
