[netic]

HI guys,

I'm installing an new finder to my boat this week and was wondering what is the best sealant to put around the drill holes where the transducer goes??

Any help would be appreciated.

Hi Netic,

You need to use a Silicone that won't hurt the alloy and this one wont.

Selleys Roof & Gutter Silicone Sealant - Translucent

It comes in a 310gm cartridge , one of those that fits into a dispenser gun with the trigger, the cartridge is blue on the front with green writing , green on the back.

I use this on my boat and have it around the screw holes on my transducer bracket. It's been there for 10 months - no leaks or problems at all.

Cheers

David.

If it is a glass boat then any marine silicone will do the job.

Hi Netic,

Try Duralac Jointing Compound, you can get it from most chandlery outlets.

It is the best stuff in that type of situation.

Thanks all, i was hoping i can get the sealant from bunnings, save me a big trip

And its an Alum boat

Any sealant that you use on a tin boat needs to be non acidic/corrosive, most household ones are not.

Sikaflex has a huge range of HIGH quality sealants, Sikaflex 291 would probably do the job for you quite nicely.

Hi Netic, if you want Sikaflex or Duralac I have a tube already opened that you can use.

Use what you want and return the rest whenever.

Let me know if you want it.

cheers

duralac is for disimiliar metals. good for stainless bolts through alloy. for glass use sikaflex. comes either in white or black.

If you were to drop into Hudsons at 84 Smithfield Rd, Edensor Park a bald gentleman by the name of Tyson may give you a tube.

Duralac is designed for use in situations where you have stainless steel in contact with aluminium and it reduces any chance of corrosion between the dissimilar metals. At least that's what I always thought??

Yep, that is correct you should always use Duralec when putting dissimilar metals in contact with each other. I am not sure what sort of boat Netic has, i may have made a false assumption that he has an alloy boat of sorts.

Just to be sure, it certainly doesn't hurt to coat ALL bolts that are going through metal or a metal fastening plate with a little bit of Duralac.

If you have a glass boat then the silicone product of your choice will be fine.

We had some electrolysis on our boat, where the screws meet the aluminium. So now we have used the Duralac and are in the process of touching up all the affected areas. It seems to be ok for now.

When my old man was up in Nth Queensland, he went into a boating shop and explained the problem we were having. He recommended installed Anodes on the actuall hull, which we have done. Iam a bit dubious but do you fellas think it will work?

Where can i get Duralac from??
