My rear end is covered in castor oil

[fastjedi]

My depth sounder doesn't work!

On investigation the reason was obvious ... a poorly bonded castor oil bath (drain pipe) has allowed the castor oil to leak into the rear bouyancy tank. I have a thin coating of castor oil over the hull and the excess cabling to the transducer and paddle wheel .... and very limited access by crawling under the cocpit sole and working through a 4" hatch

At the very least I need to clean up a small area of hull to bond a new castor oil bath to. Anybody have experience in dealing with a similar incident?

I hate the stuff , too messy

so I glued my transducer direct toi the hull with epoxy ! great stuff ! I did attach temporaly first with a white filler first and tested onec happy with postion I cleaned up and used epoxy !

Never look back and no mess !

The silva instructions recommend using water with a dash of antifreeze, seems to work OK, and if there is a leak it is much easier to clean up. for me bonding direct or through hull was not an option (boat sides at 45 degrees).

I stuck mine to the inside of the hull with sillicon sealant two years ago - much easier than faffing about with oil, and if needed the transducer can be detached.

other reports on this forum have recommended oven cleaner for degreasing the bit of hull to bond to.
No experience myself.

It seems I made a good job of glassing in the tube 27 years ago , cos its still there, so I have no expeience of cleaning up castor oil for a second try but I think I would go for water based products like household cleaners rather than solvents or products like Bilgex. I hadn't thought of oven cleaner but I think that sounds like a good idea, but what type? For oven cleaning I reckon the modern "safe to use products" are useless and I much prefer to get kitted out in goggles, gloves, welly boots and coverall in order to use the the old fashioned stuff.

What ever you use you will have to be sure to remove all traces of that as well then abrade the area where the tube is to be fitted. If you are going to re-use the old tube clean then abrade the outside of that as well. I think I bought the mounting kit from Seafarer which I assume is made of ABS because polyester resin sticks to it well whereas it doesn't to PVC, which is what you'll get at the d.i.y. stores for drain pipe. If you are doubtful try and get a bit of ABS from a plastics supplier if you can locate one.

Once you've got everything cleaned etc you can stick the tube in place with some car body filler. It's not what I used, but the type with glass strands mixed with it for bridging gaps will be best, I think. Then once the thing is firmly in position fix it securely with several layers of chopped strand mat thoroughly wetted out with resin.

Apologies for any typing errors still remaining but the keyboard seems to have a will of its own tonight.
