Hello,

  I have owned my Contest 33 hull#93 1974 for just over a year and I love it. I've read every single post here that applies on this forum, thank you. I am re-fitting nearly the entire boat and while removing the small corroded bronze elbow that goes into the shaft housing, it broke. I doubt it is of any available American pipe size. As well, the flange that tightens the packing gland did not have original studs. Does anybody know what these sizes are and where I may be able to purchase them? Thanks.

The 40 year old pipe nipple snapped off easily as I tried to remove it from the elbow. I found it to be 1/4" tapered pipe thread however there is nowhere on the World Wide Web that I can find a bronze 1/4" pipe nipple, only red brass. That leaves plastic hose fitting only option. I am not pleased with this. For the packing gland flange I'm using silicon bolts and nuts.

Is it an option to drill out the hole(s) and use another thread size? A size more common in the US?  After all it is a 40 year old Dutch boat using ditto standards   ;)

I will use bronze bolts/nuts to tighten packing gland flange. Here's new dilemma: The elbow that I removed was brass, not bronze. It is identical to the brass elbow found on fuel filter. I believe this to be factory installation. Has any other Contest owners addressed this before, the brass "L" threaded into bronze cast shaft log in sea water? Not usually a good combination. Your experience would be appreciated.

I have fitted stainless steel SS 316 hose connection and screwed it in with isolating paste to overcome electrolyse and to make it water tight.
