The Submarine would 'Float' or 'Sink' to the level of bouyancy equal to where it would here on Earth due to the similar gravity.
Since the atmosphere at the surface of Venus is equal to being underwater about one kilometer, short of damage from heat (467 degrees C) any object that would float at that pressure in water on Earth would float on Venus.
A submarine could float at a point where the atmosphere is about 3-4 bar (about 45-60psi) which would be about 40 Kilometers high, and runs about 110C for ambiant temp. It could 'Dive' by taking in the ambiant air, but would not be able to 'Vent' the chamber afterwards to rise.
The prop also wouldn't work as well. Even though the atmosphere has a similar pressure to water, it is still a gas, and unlike water, compressible.
A 'ballon' made with a thick metal skin would be able to float in a temperate region without much problem. Except for the one problem both the 'Submarine' and the Ballon would have - the temperate region has high winds, and clouds made out of Sulfuric Acid.
Beyond that, smooth sailing!

Why is venus the bright planet?
Venus is the brightest because it is very close to the Earth. Venus has a very reflective atmosphere that reflects light.
Which planet is known as Veiled Planet?
Venus
What planet is not closest to the sun the planet is the hottest because of a thick atmosphere of carbon deocide?
Venus is the planet that is not closest to the sun but is the hottest due to its thick atmosphere of carbon dioxide, which creates a strong greenhouse effect that traps heat. Venus has a surface temperature hot enough to melt lead.
What planet is warm with a toxic atmosphere?
Venus
Is Venus a gassy planet?
It does have a dense atmosphere.
What planets are on the planet Venus?
There are no planets on venus. Venus is a planet.
Why is venus the bright planet?
Venus is the brightest because it is very close to the Earth. Venus has a very reflective atmosphere that reflects light.
What is the most popular planet in space?
Venus because of it's acidic atmosphere
Is the Venus blue planet?
Venus appears to be blue because of the gases in its atmosphere. The temperature on Venus is around 870 degrees Fahrenheit and its atmosphere consists of carbon dioxide and sulfuric acid.
Why isn't mars the hottest planet?
Because it is the fourth planet from the Sun, in the solar system. Mercury is the first, but Venus (second from the Sun) is the hottest planet. That's because of the strong "greenhouse effect " of the atmosphere on Venus.
Which terrestrial planet has the most atmosphere Earth or Venus?
Venus
Which planet has no atmosphere and no moons?
Mercury has no moons and no atmosphere. Venus has an atmosphere but no moons. Mercury probably has no moons and no atmosphere because it is very close to the sun.
Which planet is known as Veiled Planet?
Venus

Venus is the planet that is not closest to the sun but is the hottest due to its thick atmosphere of carbon dioxide, which creates a strong greenhouse effect that traps heat. Venus has a surface temperature hot enough to melt lead.
Why do astronomers refer to Venus as your sister planet?
Because it is close and almost the same size. When spacecraft were sent to Venus it was discovered that it is actually very different to the Earth, with a dense atmosphere of carbon dioxide at very high pressure, 93 atmospheres at the surface, enough to crush the casing of a submarine.
Which inner planet has the thickset atmosphere?
Venus.
Is Venus a gassy planet?
It does have a dense atmosphere.
