G'day Arthur and welcome to The Board. What area are you from?
I'm in Berry NSW.
My friend Peter and Board Member (pmac) is from Erowral Bay (NSW South Coast) still has (or had?) the same vessel. These boarts are very rare and a head turner amongst the inboard fraternity. http://www.board.net.au/yabbse/index.php?topic=1058.0
At the top of this page, you will see a button maned Search. Click on this and type "Electra Inboard".
We certainly look forward to seeing some pics of you rig and we are always happy to offer free advice, based on previous experiences.
