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!

Venus is one of the hottest planets because its temperture is in the eight hundreds.
Venus is the brightest because it is very close to the Earth. Venus has a very reflective atmosphere that reflects light.

There are no planets on venus. Venus is a 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.
Acually venus is the hottest planet because venus's atmosphere is composed mainly of co2. because of this venus's atmosphere has a extreme green house effect were all of the solar radiation is trapped in venus's atmosphere.
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.
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.
