Fw: Question for Sumio or anyone else that might know about the heal gudgeon assembly

BCC Forum
1

The heel gudgeon is through bolted to the hull creating leaks which I
currently use to drain the bilge of any rain water that gets in. According
to the notes I have the interior heel area is filled with resin and mish
mash making a solid mass which should seal all the leaks around the
bolts.
Is it necessary to use compression tubes
sleaved over the bolts or externally bed the gudgeon with 5200/Lifecaulk?
Is
osmotic absorption into this resin mass at all a concern?

Thank you for your thoughts.

Everyone,

Myself and a few others have discovered that from time to time all of the
postings here do not make it to our inbox for some reason. If you have a
question for me at Sam L. Morse Co. please email or call and I will be happy
to help you out.

Hi Donald,

Thanks for the inquiry. A plywood dam is fiberglassed into the hull and
mishmash is resined into the space formed. Note that the propeller tube
extends through this space and that alignment is critical. Please consult
your building plans for the correct dimensions. Since the mishmash and
resin form a solid structure, no compression tubes are needed. The gudgeon
bolts will not be visible inside the hull. It is very important to bed
every underwater fitting heavily in 5200 or other polyurethane bedding
compound. These bolts are certainly included, and an argument can be made
for drilling the holes a 64th of an inch oversize.
Our current standard procedure includes countersinking any bedded hole
slightly to ensure a “washer” of compound. We do this above and below
waterline, into most materials. Below the waterline, we take the extra step
of coating any exposed fiberglass edge, such as a bored hole, with resin,
either vinylester, epoxy, or polyester, in the effort to seal any exposed
fibers. Use plenty of 5200, coating the bolts, filling the holes and
buttering up both hull and gudgeon. No worries over osmosis.
