I bought Dancer ( Parker 325 No. 34) jointly with my partner, and since his passing, am reluctant to part with her despite general ignorance of maintenance required. I would appreciate a check-list/schedule if anyone has devised such a thing. How vital is it to replace the anode in the lift keel? How often ? Ballpark figure for time required/ cost?
Has anyone an "expert" who can offer guidance/tips on doing this? Dancer is in Portland, and I believe the yard is inexperienced with Parkers- so help and advice would be very welcome.

Welcome to the PSSA forum and very best luck with the boat.
There used to be a detailed explanation of how to service the 325/335 keel on the website. If it is not still there I will happily send you a copy. Also I have the guide from the original owners' handbook which I can send too.
Maintaining the keel ram is essential, there was recently a picture on the forum of the disaster that can occur if it is not done.
The ram needs to come out and have the anode on the lower end changed once a year or at a stretch every other year. It is not a difficult job but can be a bit of a fiddle; my wife and I can usually do it in about three hours from start to finish; it can be done with one person but is quicker and easier with two. Once they understand what to do, I would expect any reasonable boat yard to be able to do the job for you.
We are on the east coast but with a bit of luck someone nearer will be able to show you what needs to be done.

Thankyou Martin. It is so reassuring to have a helpful response.

I think I have a photocopy of the owner's handbook-pages 2A-E seem to deal with the keel? I also have a couple of A4 sheets entitled Lifting keel- procedure for replacing hydraulic ram anode (16 steps) & Tools/equipment required. Some handwritten notes include details of anode- ZSC 35mm diameter, is this correct to your knowledge?

I have not found anything on the website, could you (or anybody else) direct me?

Crucially, Lee, Boatcare manager at Portland would be interested in talking to someone who has done the job- would you be up for that by any chance? I could give you his number.

PS Does the 3 hours include other hydraulic maintenance checks, or just for the anode?

Attached ( I hope) is a scan of the information I have on keel maintenance, the first four pages are from the Parker handbook and the last three are the instructions that used to be on the PSSA website.

I am not sure what hydraulic checks you have in mind, all I have ever done is check the oil reservoir level whilst the keel is fully down.

Three hours or there about covers opening up the keel box, removing the bolt at the lower end of the ram, removing the top hanger pin from the ram, disconnecting the hydraulic hoses, lifting the ram out, changing the anode then replacing the ram, pin, hoses and bolt. It is all pretty straightforward although getting the lower bolt and top pin back in can be a fiddle.

I would be happy to chat to Lee at Portland, I will email you my details.

Hi Martin!
Thankyou so much for all the information! I have passed it along to Lee, and if you could speak to him that would be brilliant! I have my grandchildren coming overnight, so will be a bit preoccupied with my "bubble" today & tomorrow, but will pick up again Sunday if not before.
Cheers!

New/updated articles are welcome!

Hi Heather,

I remember Dancer when she was with a previous owner. It’s good to know she remains in good hands. You mentioned “boatcare” and Portland. This means you are with Dean and Reddyhoff, now Boatfolk. Me too, at Deacons at the top of the River Hamble. Parker 325 Kerenza is also based at Deacons. I don’t know how much boat servicing owner Jeremy has received from the Deacons team since he moved here but I will ask him. Nick, manager of boat care across a number of boatfolk yards, has an excellent reputation. If there’s experience here he can pass it on to the crew at Portland.

When the weather is fine a number of Solent based association members, me especially, love to head down to Weymouth. If the weather and timing are convenient this summer, perhaps we could meet up in Portland or Weymouth. Fingers crossed for a good season and good luck with your maintenance.

Ken. (P275)

By the way, I think I saw Dancer in Weymouth last time I visited. At the bottom of the entrance ramp, turn left. I'm realising that you visit Portland for yard work. In this case we'll look out for you next time we visit and come and say hello if you are onboard.

I just tried to call the 325 owner in Deacons but he, Jeremy, is not in at the moment. I will try again later.

One or two additional tips as I wrote the original instructions for changing the anode which appeared on the website having done this numerous times.

It is not necessary for the keel to be fully lowered, in fact it is a bit easier if it is not, but it does have to be lowered sufficiently for the lower bolt through the keel to be accessible.

When changing the anode it is best not to disturb the lower eye through which the lower bolt through the keel attaches. This eye is screwed in and if you don't replace it exactly as it was before the effective length of the ram is altered.

It is helpful if the open end of the hydraulic hose can be blanked off. The weight of the ram cylinder will tend to force fluid up out of this hose thus allowing the ram to slowly 'collapse', i.e. the ram will push itself back inside the cylinder. If this happens the top of the ram will no longer align with its hanger and you will then need to try to pull the ram up so you can fit the top bolt - no easy feat given the weight of the ram and the outside casing will doubtless be slippery with hydraulic fluid etc.

Be careful that the anode is not significantly thicker than the one it replaces otherwise it could foul against the bottom of the cylinder when the keel is fully lifted.

When Tilikum was new I used to replace the anode each year but after a while I stopped doing this as I tend always to leave the boat with the keel up, the anode is therefore out of the water, if I am not on board. Depending upon how much sailing one does, I find that replacing it every 3-4 years is in practice quite sufficient.

It looks like you have all the help you need with this but if you need any more advice I am happy to give it.

Thanks Ken - was it my late partner, Steve Parker you remember? We attended a couple of rallies when we first had Dancer at Deacons, and believe we may have met Karenza at the Isle of Wight. We moved to Weymouth for 2012 as Steve was a volunteer at the 2012 Olympics. You are right in your surmise, Dancer is over in Portland till the end of April for some TLC. Please do get in touch when you are coming to Weymouth, it would be good to meet up!
Best wishes, Heather

Thankyou Jonathan, both for the original instructions and notably this additional pointer. It is good to be able to tap in to such knowledge & experience. Thanks also for the offer of further help if required.
Cheers, Heather

Just to belatedly chip in my two pennies worth!
There is a post on using an overboard anode connected to the ram .. I'll see if I can find it.
Mike Lockwood said "However, we inserted a stainless steel bolt through the deck hatch above the keel, connected this to the top of the keel with a coiled wire. When not sailing, we connect the deck end of the bolt to an over-the-side anode (an old hull anode usually). We measured a 0.5V potential between the keel and the over-the-side anode. Some battery! Extracting the ram is not the easiest job but is essential. Three pairs of hands make it a little easier. We also keep the keel up when on our mooring."
Having a cradle saves time pressure. I have to rely on the yard's boat mover, so their last job of the day is to lift me on the slings until I can just see where the bolt hole will be, and leave me there. I then have to lift the ram, replace the anode and refit the ram before the light goes and the yard returns the next morning to put me in the water! I use the main halyard to ensure the lifting and lowering is under control.
There is an awful lot of detritus around that lower eye bolt. Power washing and scraping allows the eye bolt to go back into its place.
Unscrewing old hydraulic hoses can mean that on reconnecting there can be a slight weep, with consequent loss of fluid. I found this the hard way, and simply refitted using plumbers PFTE tape. I did this after asking about and being told that would be fine. Comments welcome.
I think it was obvious, but secure the lower eye bolt first. Having the ram on a halyard means that wiggling about can be safer. When the eye first appears get a screw driver in there, and try and get it to line up with the bolt.
Cover everything - but obviously not the anode - with Denso tape and grease - see https://denso-tape.co.uk  Ferries use it. It was covering the ring anode with Denso tape that probably caused the corrosion that locked the piston in my ram.

For a story on how to replace the whole ram once it had seized solid in the "up" position ...

Oh, and take great care with the keel depth transducer - detach it carefully before starting work, and tie it back out of harms way. And tie lanyards to all your tools and attach them to you!

I’m going to replace the keel ram anode this weekend. I read that two 30 mm sockets and T-bars are required. The picture of the lower keel ram bolt however indicate the head is 20mm. Where are the 30mm sockets to be used for?

I am fairly sure that the bolt on the lower end of the ram on our 335 (No50) is 20mm diameter with 30mm head and 30mm nut.
The boat is in the water at the moment so I can't check!

That is clear Martin. Thank you for your clarification. Now I understand and I think I have the right tools do do the job with my youngest son tomorrow
