I've have had a few replies I made just disappear after hitting "send". Just testing to see if this posts.

Craig,

I have changed mine several times - use both membranes. Be very careful not to drop parts down sump - I block sump opening with a sheet in case!

Good luck

Hi craig, as a last resort, I looked in the equipment manuals supplied with the boat, and there is an exploded diagram showing the 2 diaphragms in the assembly so question answered. Use both, the one under the white paper goes on the air side.

Maude was super helpful and had the part in stock to replenish my spares cabinet. Hopefully will last another 5 years.

Hi Bob,

Just one, as I recall.  It'll become clear, of course, when you open up the pump. Wear gloves - yucchy job !

Cheers,

Hi guys, I have a Reya Marine ZZ bilge pump that started leaking, caused by a torn membrane, luckily had a maintenance kit in my spares box, there were two separate membranes in the kit along with a big o ring and 2 valves.

The question I ask is do you use one or both membranes in the repair? They seem identical.

I couldn’t find any online reference guide or pump exploded view to answer what is probably an obvious answer “ use both “ but as I’m sure there are many Amel owners who have repaired their pump and know the answer.

Hi Ryan,

I'd recommend Selden Mast's booklet Hints and Advice on Rig Tuning - you can download the pdf. They give a neat "folding rule" method (pg 32) of determining tension based on the fact that 2 meters of any diameter of 1X19 wire stretches 1mm for each 5% of breaking strength applied.

So, for example, if you want to tension your 12mm cap stays to 20% (Amel tight, maybe!) just tighten them until 2 meters stretches by 4 mm. That stretch will give you about 5600 pounds of tension, as the breaking strength is about 28000.

The Loos gauge doesn't handle wire over 10mm (actually 9.5 mm as it's rated for 3/8) and only goes up to 4500 pounds. That's why the results Nance and Underwood gave Steve Morrison in his post just show "very tight" for his 12mm stays.

After you get a sense for "very tight" you'll get to trust just feeling the stays and being able to judge if they're right. And use Joel's suggestion to go out, sail upwind in a good breeze and see if your lee shrouds are at all slack. If yes, they're way too loose. Oh yeah, and recheck after a while as the wire will stretch over time.

On the headstay there is a turnbuckle screw under the furler. ACMO just calls it "special" , as it's shorter than standard ones so the furler can be closer to the deck.

Have fun tuning!

Hi all,

I'm about to embark upon tuning up my rig, which I feel is a little loose, but I'd love some guidance on how to do that.  I've scoured the archives of this list and found many mentions of guides from both Joel Potter and Olivier Beaute, but I haven't been able to find them.  The best guide I've found thus far is this one.   Can anyone link me to the gold standard(s)?

Also, has anyone done the tuning in a more scientific way, with a Loos Gauge?  I'm struggling to understand via qualitative descriptions just how tight is tight.  I think a quantitative measurement would be very helpful.

And finally, how does one adjust the forestay tension?  I admittedly have not studied it in depth, but I didn't see a turnbuckle or any other obvious mechanism.

Thanks,

Ryan
