You want to measure an angle ?
What is the angular speed of the sensor ?

I need to be able to survive immersed in fresh water for several
minutes. I think I might be able to get away with IP67.

I need to be able to measure an angle 0-360, & can't directly couple to
the shaft/axis of rotation. I can put a gear on the object to be
measured, & due to space constraints I need to reduce at least 5:1.

Angular speed would be slow, probably no more than about 30 RPM.

Is cost an issue or are you able to look at synchro/resolvers as a means to
measure the angle. There are some around that, due to their construction,
are OK for immersion. The solution is more expensive than a pot for
measuring angle but is quite dependable.
