O script revela que Indy se atribui ao periscópio :
Indy climbs the ladder to the top of the turret and braces him- self between the two uprights there--the 7 foot radio mast and the 20 foot periscope.
Still the ocean comes up to meet him. Soon the top of the turret is under water and the radio mast is disappearing.
Indy shifts his grip to the periscope, working his way up it and hanging on for dear life as the ocean whips at his body. The periscope is quickly going under. Indy hangs on to the top three feet, all that remains above.
The forward movement of the sub continues, but, to Indy's slowly dawning delight, the dive stops. No more of the periscope goes under. Indy smiles; it's a pretty good smile, too, given the circumstances. Indy pulls out his bullwhip and begins tying himself to the periscope.

The periscope ride
This is the most well-known of the Indy cut scenes, by virtue of being the one most crucial to the plot. This scene explains how Indy survived his trip at sea attached to a submerged submarine. As the sub descends, he climbs up and grabs hold of its extended periscope. He then lashes himself to it with his whip for the long trip.
