Bavaria Yacht Help! / Lower bearing ball stuck

Last post by Viviane2000 - November 05 2025, 19:44

To check my sanity, the lower bearing ball should be able to move right?
I tried hitting it with a hammer and a piece of wood, no movement whatsoever.

Our steering was very light, with the seized lower bearing ball. So for the time being I'll leave it as it was.

In about 2 months we'll get a new rudder. It seems wise to order a new lower bearing ball at Jefa at the same time? Then I'll cut this bearing ball in two and remove it. Or could the lower bearing house be at fault?

Bavaria Yacht Help! / Re: Bleeding the fuel system

Last post by Diverphil1 - November 05 2025, 16:30

if the first filter is a cav type they can be a sod to re seal, make sure the top o ring is in its groove correctly and not twisted, then fit the filter up to the grove and seat it, then whist holding the filter in place fit the bottom bowl up to it, then finally while pushing up from the bottom re fit the center bolt. don't forget to renew the center o ring and the bolt o ring.
its a bit of a 3 handed job but practice makes it easier.

as for the other filter its just strait forward screw on type.
 
if after checking these and that the fuel tap is open then maybe your primer pump has had it. to check that remove the input pipe and put your thumb or finger over the hole to see if it is sucking anything up.

Thanks. Yes, mine is the top one. Do you see how the seal is shown above the thermostat not below?

This is the dilemma.

Tyrone,
Page 73 of the workshop manual shows two types of D2-55s with different thermostat arrangements.
That manual is in the download section post #109
May shed some light on it.

Bavaria Yacht Help! / D2-55 Heat Exchanger

Last post by moonlight_shadow - November 05 2025, 11:49

Hi All,

I have just finished overhauling my heat exchanger on a volvo d2-55 and have a bit of an issue with the thermostat installation.

Parts diagram shows the thermostat seal goes in first, then the thermostat. Workshop manual shows the seal above the thermostat and just below the spacer sleeve.

It was installed originally with the seal first, but i noticed that this way the spacer sleeve protrudes a bit too much and is resulting in a lot of pressure on the housing cover.

Any one has some thoughts or experience to share about this please?

Thank you
Tyrone

Bavaria Yacht Help! / Re: Sudden crack in C41 Perspe...

Last post by Impavidus - November 04 2025, 20:21

Looking for help. Yesterday discovered vertical crack in port side deck window on lightly sailed C41 9 years old. No obvious idea as to reason. Bavaria agent says need to change to glass now as Perspex faded out by Bavaria. That means changing 4 windows!! They have estimated at about £900 plus vat each plus fitting !!!! Talking £7000 plus!!! Do Bavaria have replacement Perspex windows or a template to cut too?

This is a known problem with the Farr design hulls. I have posted a previous article with regard to leaking at the joint between the two sections of window and the adhesion of the 3 way joint.
The exact same issue has just happened to our 2015 Bavaria 37. The starboard side window has split at the forward section. The port windows are showing the same level of stress cracking. I used to work in the window and facade industry so it is a subject I know a bit about. The issue is due to the rate of thermal expansion between the deck molding in white and the cast acrylic sheet that is dark tinted.

BAVARIA ARE AWARE OF THIS LATENT DEFECT.

The deck molding and the acrylic expand at different rates in strong sunlight. The rate of expansion is very pronounced and this causes stress fractures in the acrylic and leaks at the joint between the saloon window and the aft cabin / heads shower, depending on your model. The adhesive (mastic) used is a high modulus polysulphide mastic / bonding compound that has an in use lifespan of around 5 years. 
Even the very best glazing / bonding mastics from Arbosil, Sika or Dow Corning only have a lifespan of around 8-10 years. Commercially Dow will not warranty their products above 10 years and that is if production samples and batch tests are carried out during the glazing process.

So where does that leave us? 

We are going to replace the saloon / aft cabin / heads window set on both Port and Starboard. We are going to ask a company in the UK to produce the new cast acrylic windows from templates we will make in a few weeks time. The projected costs are around £300-£400 for all the window without the fritting.
We/I used this company when we were in business they are very professional. When and as we do this project we will cover it on our YouTube channel.

Footnote; The rate of thermal linear expansion between monolithic glass fibre castings and mouldings is very different from the rate of; Toughened glass (not really suitable in this application) standard float glass (a dangerous choice) The best choice is heat soak tested toughened laminated glass (4-2-4) 10mm which would be the best choice but it will debond after time because of the thermal issues.
We will keep you all updated as we look at this issue, Meanwhile,  Bavaria know the issue and will keep kicking the can down the road.

If enough people respond we would be happy to take this on with Bavaria, make a video on the issue as there are a lot o the Farr designed hulls that are having the same issue and will need remedial works.

Bavaria Yacht Help! / Re: Saildrive seal replacement...

Last post by mibbal - November 04 2025, 07:51

Hi MagicalArmchair,

I know this topic is quite old, but I'm going to perform same task and replace saildrive seal on my B40 2001 with MD22 (it has not been replaced since new).

Provide my boat is same as yours, I would appreciate if you can clarify few details from your experience:

1) Are you satisfied with your frame? I would build the same as per sizes you mentioned above.
2) How did you fix upper part of the halyard? I'm thinking of placing a plank above the salon entrance to fix it, but I'm not sure if fiberglass around the entrance is strong enough.

Any other advises are very welcome!

Bavaria Yacht Help! / Re: Corrosion rudder stock. Do...

Last post by Happysailor - November 03 2025, 17:49

Well... I happen to know Curacao quite well and with regard to welding capacities you may get surprised.. they have Damen Shipyard and also previously a refinery.. you also need good (boiler)welders and machineshops in those places. Perhaps the shipyard or their partners can help you out for ND testing of the rudderstock and weld / flamespray / HVOF coating to beef it up again? https://www.damen.com/companies/shiprepair/damen-shiprepair-curacao  https://dickanddoof.com/
Always worth a try...

Thanks for the suggestions. If someone can guarantee they can fix it without the rudder losing its strength I'm of course willing to consider the option.

I've called both Damen and Dick and Doof, they can't (or won't) help.
I've also contacted https://www.turbomachineshop.com/, maybe they can help

What a pity! Getting local help at least to assure this meandering cracks have not taken place would perhaps help you to get the boat to a better place to repair or to start your journey while ordering and shipping out a replacement to a next convenient spot to receive the goods (flights/ customs etc etc) Good luck and hope the locals will be supportive to guide you to someone to help you out!

Btw, I've contacted JP3 as well. This was their response: "We thank you for reaching out to JP3 about the repair of your boat. JP3 hasn't supplied Bavaria ever

Odd! I wonder why their name is on so many old Bavaria steering parts then
