Bavaria Keel - Here we go again!

Tranona said:
Quite difficult to get water out when the boat is stationary as it is individually only small amounts in each and often below the level of the limber holes. That is why it comes out when the boat starts bouncing around. The total amounts are small and unless you find the source will just keeping going in a continuous cycle! Concentrate on mopping out the bilge and then checking all the obvious sources of leaks. Can be very frustrating finding them but you may be lucky and it is one of the obvious ones like the muffler, water pump, calorifier, transom shower.

Sail drive seal or shaft seal?

The boat has a sail drive; the seal was replaced four years ago. Also there's no obvious way for (small) quantities of fluid to get from the engine compartment to the bilge; I spilt some oil there when I changed the filter a year ago, and that's where it has stayed.
 
It will run from the pointy end though quite easily to the keel bolts- that said having washed out our Bav bilges with hot water it’s amazing how long it can linger all around . There seem to be a number of sources of freshwater leaks but it’s saltwater then dye might be a way of spotting poured around a fitting .

If you want to "moat" the keel bolts, just get some rubber bungs and put them into the limber holes in the section where the bolts are.

That's an excellent idea! Doh! (For the avoidance of doubt - I think that's a great idea, the 'doh' was directed at me for not thinking of it.)

A good way to make a moat is good old fashioned plasticine. Buy loads, for two reasons, A. To make sure you have enough in hand to make as many moats as you may need. B. To ensure they keep making it for my very young grandson to enjoy it when he stops putting everything in his mouth.
Good luck,

It is worth noting that all the J&J design Bavarias from mid 1990s to 2009/10 share the same basic design architecture and share many components. Bit like BMWs - sold by the length like sausages - just cut off at the size you want. They are pretty bullet proof with very few basic design or construction flaws. There is a useful survey here which covers just about all the known problems, mainly related to the J&J designs. Good source from anybody thinking of buying a Bavaria or has just got one and finding their way around it. bavariayacht.org/forum/index.php/topic,1931.0.html

Don't use Flour ... better is common Talc
Click to expand...
Johnson &Johnson just announced their “talc” will be cornflour in all markets going forward since actual talc had asbestos in it and was carcinogenic. So may as well use flour ?
 
An earlier poster mentioned exhaust hose and that reminded me I looked at a chap’s boat when we were in Ramsgate a few years ago as he had a leak in his Bav. Eventually found it in the metal exhaust water lock which had a leaky weld or was perforated (can’t recall) Maybe irrelevant to your prob but another thing to rule out. Good luck ?

Actually not correct ..... J&J announced after a Court Ruling against them - put by a group of women who claimed Ovarian Cancer - that CORNSTARCH would be used instead of Talcum Powder (Hydrated Magnesium Silicate) in some of their products and would be labelled accordingly.
Asbestos was not actually found J&J or other brand and is mis-reporting by media.

Asbestos was looked for as during mining of HMS - natural veins of asbestos may be found.

Cornstarch is not Cornflour - although they have same source.
 
If you told your insurer at the time of the initial hit then they will have it logged.
The vessel should be lifted and inspected.
Most insurance policies cover bottom inspection .
Down side if you have shopped around and changed insurers then your current insurers would rightly refer you back to the actual insurer at the time of the hit and if you did not report could find yourself time barred.
I always believe to stay with your insurer in the event of something that could go back a number of years as they in all probability would look at more reasonably as a continuing customer.
Sorry to say an inspection after a hit a job for the professionals not DIY.

Are the Johnson and Johnson the same J&J Tranona talking about ,

Cool you learn some thing new everyday ?

The difference between corn starch and corn flour is which continent you say it on. They are the same thing.

Cornstarch vs Corn Flour: What's the Difference? - The Loopy Whisk

The difference between cornstarch and corn flour
Both ‘cornstarch’ and ‘corn flour’ are terms commonly used in the US.

Cornstarch is obtained by extracting the starch from corn grain, specifically from the endosperm of the kernel. It is almost 100% starch, without any fibre, protein, fat or other components. It’s a very very fine white powder that’s chalky in appearance and that ’squeaks’ when you rub it between your fingers. Cornstarch is often used as a thickening agent to thicken sauces and custards, like for example vanilla pastry cream.

Corn flour is obtained by grinding entire dried corn kernels into a fine powder. It’s basically very finely ground corn meal. In addition to the starch, it also contains fibre, protein and a small amount of fat. There are two types of corn flour: the more common yellow corn flour that’s made from yellow corn, and white corn flour made from white corn kernels

Yes, already on the list of suggested checks - from personal experience with 2 Volvo mufflers in Bavarias.

The boat has already been lifted and checked. If you read the whole thread you will see from people who have years of experience with these boats that it will almost certainly be nothing to do with a leaking keel bolt, but water accumulated from elsewhere. These boats and their keels are very robust and damage that would result in water getting up the keel bolts would be massive - not least distortion of the grid immediately behind the bolt in question. The OP reports no such damage either internally or externally.
 
I wouldn't use flour, or anything else organic anyway. It will go mouldy or feed cockroaches. Talc, powder paint, chalk powder etc are far preferable.

Our exhaust leak was very hard to spot as it was oozing all over. Under the fabric cover the pipe had degraded completely and become crumbly. We had a known leak in the calorifier at the same time, which didn't help as they were close together. The calorifier stainless steel has become porous and had several tiny leaks.
 
‘Corn flour’ is a milled corn product - for instance, as used to make a corn tortilla.

‘Corn starch’ is a processed corn extract used as a thickening agent in anything from gravy to custard to cakes. It is indeed widely known/sold as ‘cornflour’ in the uk. The two products are substantively different things.

Funny direction this thread has gone, eh? I’d just use blueroll anyway!
