Title: Fiberglass question
Post by: SWIFTMIKE on July 22, 2013, 07:20:04 AM

Ok, so I am in the middle of replacing my transom and installing a Berkeley pump into my hull......my question is what glass and resin should I use to glass in the transom and what should I use to fill the hole where the pre existing intake for the pump was.  I have decided to stay away from epoxy resin just for cost.... I am just mostly interested in what weights of cloth/mat you recommend and  what would be the best process/material to seal that large hole from the intake so I have a fresh start for the new intake.

Thanks In Advance
Mike

hang tight.

 you will get info shortly.... lots of it.

 in the meantime check out a website for West Systems ....
another info source is from Allen Vaitses book 'the fiberglass boat repair manual . 

my one bit of advice is this: don't substitute perceived inexpensive materials for what is necessary to make the repair right. a large hole close or under the waterline is NOT the place to compromise either materials or workmanship. 

good luck!!!   send pics!!!!

Thanks for the recommendation on the book! I ordered it from amazon!  I have looked at the west systems products and I know that they are good quality but the stuff is just expensive and fro the amount of work I have to do.....the cost of the epoxy resin would be more that the boat is worth!  I know that a good job can be done with a vinyl ester resin or polyester resin.....Im just curious as to which everyone prefers and cloth/mat weights.

Thanks
Mike

Talk with the boys over at sher fab in ontario. They will have everything you need and will give a bunch of advice. Try and talk to A.J he is the guy to talk to. Epoxy is very Pricey right now. I would go with a polly resin and some 1708 bi-axle matt for the transom.  For the intake hole i would back the bottom with some sort of plastic with PVA and do multiple layers of 3 oz mat and 10 oz cloth. Maybe add some 1708 in there. JMO
