Submarines on lake winnipesaukee?

When i was a kid I watched a guy launch a homebuilt submarine at Thurstons.

This would have been some time early 80's.

It was constructed out of a big propane tank with a hatch welded onto the top / middle of it. Rocks hung beneath in a welded wire rack for ballast.

I dont think it actually went completely under water, it was powered by what I believe was a 4 cylinder automobile engine with a prop straight out the back. For cooling it had baseboard radiators run along the outside of the submarine.

It was the maiden voyage and I remember him commenging that he fele the prop and rudder were undersized for it and that it got really hot inside.
