Bavaria Yacht Help! / Re: Jefa Rudder Bearing Housin...
Last post by GeoffV - July 23 2026, 10:07There is a video either on the Jefa website or Tube showing a technician doing the 3 year service.
It looks very strait forward. The key to it all is the greasing of the bearing and holder stopping the corrosion which stiffens up the whole thing.

Bavaria Yacht Help! / Re: Jefa Rudder Bearing Housin...
Last post by sean c - July 22 2026, 11:30I replaced the lower rudder bearing and housing on my 47 Cruiser 2009 last December. I had a lot of trouble identifying the bearing size as the Jefa drawing for my model did not list it.
Yours appears to be on their site though.

They sell the complete housing, ball and nut kit.
https://jefa.com/ftp/old_boat_spare_parts/Bavaria/Bavaria36_A36_2010-2013/5BT084-129.PDF
Have a look around the Jefa site. It is badly laid out and difficult to navigate. They recommend not putting copper based anti-foul within 50mm of the bearing housing. They also recommend ball bearings be removed every 3 years and thoroughly cleaned. Not sure this is practical if you have to destroy it to get it out.
The original bearing housing I removed had a stamped JP3L/SW.I ended up getting a JP3 non roller bearing. They sell a blank and I got the hole machined out to their spec after I had the rudder out.
The SW on the housing I was told stands for SeaWay who made the bearings on license to JP3 from Slovenia. They had some issues with deviating from the standard design.
When I got the new bearing housing it was 40mm shorter than the one I removed. The JP3 agent advised this was the correct spec and I need to modify my boat to fit the bearing. It all ended up OK with a good fiberglass technician modifying the hull.
When I walk around boats on the hard stand they are almost 100% anti-foul on the bearing housing same colour as the hull. I don't believe many people follow the manufacturers recommendations.

Bavaria Yacht Help! / Re: Bavaria 42 - 2001. Selden ...
Last post by Mirror45184 - July 11 2026, 09:26The photo of the assembled tang does not indicate any significant misalignment or side load on the swage which may cause a premature failure. The stay terminal is not tight in the tang fitting which would allow for some misalignment.
If you are tightening the D1 when sailing to remove movement this may be overloading the D1. When sailing the leeward shroud and D's will all have some slop in them as the vessel flexes and the windward shrouds/D's stretch slightly under load, this is quite normal.
If the mast moves out of column (straight) when under load then the D's will need to be adjusted to bring the mast back to straight in the loaded condition.

Bavaria Yacht Help! / Volvo Penta D1-30: Engine losi...
Last post by gadisac - July 09 2026, 09:27Hello everyone,
I'd like to share an issue I recently experienced on my 2006 Bavaria Cruiser 37 equipped with a Volvo Penta D1-30 and SD130 saildrive. The engine has approximately 2,600 operating hours, and I hope this information may help someone facing similar symptoms.
While motoring at a steady 1,500 RPM (I have an Autoprop propeller), the engine suddenly started losing RPM and eventually stalled. After restarting, it would no longer idle properly and was unable to maintain its normal idle speed of around 900 RPM in neutral.
Interestingly, no engine alarms or warning lights were triggered.
At the beginning of the winter lay-up, I had performed the annual service, including changing the engine oil, the oil filter, and the fuel filter. The fuel tank was also completely full, so contaminated fuel did not seem to be an obvious cause.
Once back in the marina, I started with the usual checks. I replaced both the Volvo fuel filter and the Racor pre-filter, and I inspected the diesel for microbial contamination. The fuel was clean, with no sign of algae or debris. Both filters were also surprisingly clean.
However, while replacing the engine fuel filter, I noticed that it was only about half full of diesel. This suggested that the fuel supply to the filter was insufficient, leading me to suspect the mechanical fuel lift pump.
Fortunately, I had a spare fuel pump on board, so I replaced it.
Afterwards, I disassembled the original pump out of curiosity and discovered something I had never noticed before: inside the pump, beneath the small cap on the top, there is a small serviceable mesh filter.
This internal filter was almost completely blocked by algae and microbial deposits.
After installing the spare pump, the engine immediately returned to normal operation. It now idles perfectly and runs smoothly throughout the RPM range.
Lesson learned: even if the primary fuel filter and the Racor filter are perfectly clean, don't forget that the mechanical fuel lift pump itself contains a small internal filter that can become clogged. It is easy to overlook because it is not part of the normal service routine, but it can seriously restrict the fuel supply.
From now on, I will inspect and clean this small filter during every annual service.
I hope this experience helps other Bavaria and Volvo Penta owners. Has anyone else come across the same issue?
