Re: KD3 mercury

I have a KD4 which uses a similiar split tank arrangement .
i split the tank,cleaned out all of the old gasket material from 1947, got some gasket material (Feldpro Karropak .065), put some ThreeBond 1184 grey on one side, clamped the tank together overnight . Took it apart, now the gasket will remain put,then with a new Xacto knife cut around the inside. Once you start at one edge it really easy, just use the edge of the knife and follow around. For the center gaskets just cut circles, and use a paper hole punch for the stud holes. When the gasket is cut apply some ThreeBond to the other half. and bolt up. Another advantage of splitting the tank is that you can really clean the inside with a wire brush.
This method worked for me, your choice, and it was relatively inexpensive to do.
