What glue would you use to attach the prop shaft where it passes through an ABS hull, so As to seal it from water ingress
Thanks in advance  :angel:

[alan colson]

I always use a 2 part epoxy, when I have the glue around the shaft I twist it to make sure it has sealed all the way round.
Hope this is of help

Yes 2 part epoxy is the stuff

[DickyD]

I'm with these two, two part epoxy.

It is very important to roughen up the ABS where the glue goes for a good bond as epoxy to ABS is essentially a mechanical bond. For a strong chemical bond I would use Stabilit Express (eg as on my Robbe PT15).

... I`ll join the forespeakers, but don`t use Stabilit Express as it may crackle after a while. Same do some 5Min-Epoxys. I prefer either Uhu Endfest 300 or some other, slow-hardening 2-K Epoxy glues.

Had once a try with Stabilit Express and after a year wondered about the bilge filled up permanently with water.

Also important to rough the plastik with sand-paper and clean the plastic from any release-agents which might be inside from manufacturing.

Hope it was out of any help,

3M 4200 or 5200.  Single part, very thick so it will stay in a wide gap between shaft log and hull while it's curing.  Once cured it will be just slightly resilient, providing some vibration damping.  And it is totally waterproof.  Not cheap, though.

Another concern with the five min epoxy's is that they are affected by water.  If, like me, you only discover this after you've done the job ensure you get a good coating of paint over it to protect it.

The slow curing epoxy is apparently OK and we are all going to cover it with paint anyway but it is worth knowing about the five minute stuff.

According to Z-Poxy's specification the 5min and 30min epoxies are identical except for the drying times and the fact that the 30min one forms a stronger joint.

I've been using the slow setting epoxy to set the shaft. Seal it and bed it after using the two part auto filler with the fibreglass strands in it. Have used that to set motor mounts, battery bases as well and so far no trouble.

the best thing i have found and used for years is p40 chopstrand fibreglass filler. totally waterproof sticks extremely well and is fast when holding your work togeather i can get 2 shafts 2 Kort's in one go in one night

works for me

Up to now I've always used car body filler wthout any problems and it does not run all over like the two part epoxies. 
Just a thought - what about using silicone sealant (bath sealant), it sticks like you know what to a blanket and it would cut down on vibration noise.  I know you can't paint over it but that would not matter in an enclosed hull and if you take care not to get any on the outside.  I have never tried it and, as I say, just a thought and it would be interesting to see what other mayhemmers think.
