Transom Bolt sealing??

All

I need to remove and replace a couple of my engine bolts to replace rusty washers that obviously found their way in amoungst the stainless washers ones when I put the engine on.

What do others use as a sealing agent around the bolts through their transoms?

I've used everything in the past from silicone grease and sealer to Sikaflex, which obviously makes them a pain to get out again.

Try spraying the bolts with silicone before you insert them. I would be tempted to use epoxy - just make sure you do a test run in a block of wood or something first!!!

BTW buy yourself a magnet - great for checking your nuts.............

Can't beat Silkaflex Nasher, rather than buy a new tube, I have some black I purchased to do the sealing around the instruments and don't need it for anything else. Your more than welcome to pick it up.

Thanks Guys

I've a half empty tube of Black myself at the moment thanks Andy, I'll need to go and get some more white.
Last time I used Sikaflex on transom bolts they were a right pain to get out again, but I suppose they don't come out too often.

I keep my Stainless and other fasteners in seperate bins in the garage, but must have mixed some somehow.
I don't trust the magnet with stainless, as some forms of Stainless are magnetic.
One of my commodities at Raymarine is Fasteners, and I've recently had a long drawn out battle with a mad Hungarian who claimed that some Jubilee clamps I'd supplied were not Stainless because they were magnetic.
I persuaded him in the end with help from my supplier that Stainless can be magnetic depending on the grade.

The best stainless to resist corrosion IS non magnetic - but it's not as tough as the magnetic stuff - as always it's a compromise.

Yup - loads of people think ALL stainless is non magnetic - in fact there are probably about 50 or more different grades - there are 8 grades of 316 alone!!!

Then again I'm probably teaching granny to suck eggs here...........

Try coating the threads with silicone spray - it should make removal easier - if that's what you want!!!

Nasher.

Then, if your supplier is supplying ferritic/martensitic "stainless" as opposed to austenetic “stainless” for fasteners used in a marine environment I suggest he wants a good kick in the gonads… but be aware that extensive cold working can render even austenitic steels “magnetic”….

Stroke em wiv a magnet.

Anyway, I use silicon sealer cos you can chap the bolts out with a drift when you need to.
Don't put silicon grease anywhere near where you might, in the future, want something to stick.

It reminded me of the meat pies that were sold during the war...50% horse and 50% chicken.

One horse mixed with one chicken.
