I am not sure that I have done anything other than stick it in the `ole and slap epoxy on it??? Ashley

NB…ok, I usually spot-glue it in place with superglue and check it is lined up, and motor the motor with a 1.5V battery BEFORE slapping epoxy all over the place

NNB yes car body filler is good stuff as well.

NNNNB.. no, never mind

Kip: do you mean polyester resin as this is also porous, hence why they use a gel coat on finished products such as marine hulls as the gel coat gives the resin its water tightness.

I am assuming you mean epoxy resin as this is water tight and is the only resin to use.

Hi All

This is quite a good way of making sure you have clearance from the bottom of the hull with a 35mm ply disk for a 30mm prop, especially useful on twins also the same angle when measured up at the motor end, rough up the tube & Poundland 5 min epoxy does the job.

Would like to make a comment about cheap epoxy adhesives. I purchased some from one of the cheap high street shops to hold some lead ballast in place and at the same time fill a void inside a hull. During the curing process it created a great deal of heat and smoked for a while, luckily the hull was wood and not styrene. If I use any again I will have a trial mix using a piece of scrap.
