Currently experiencing gear noise in the lower assembly but only when paddling forward. No noise when going in reverse.

there is no leakage and the unit is well greased. There is about 1/16 " vertical play in the transmission axle. The transmission

screw is tight. Aside from checking the grease status I have not opened the upper assembly. Suggestions?

I am on my third unit. The first two did exactly what you described straight out of the box.
The retailer swapped them out, no questions asked. The one I have now makes some noise, going forward, but not as bad as the first two. I'm tired of driving 3 hours to replace it, so I just deal with it.

I do a visual check on the gears and grease regularly, but I'm certain it is the bearings.

I assume the transmission axle you refer to is the one in the lower cassette.

 

The vertical transmission axle in the propel itself should not have any play.

 

I have not been successful in getting rid of this noise in my units but I have not replaced the cassette bearings yet.

 

Let me know if you figure it out.

I too have a growling or drone type noise coming from the lower unit . I have the tools and checked to make sure it is well greased . The noise is still there . It is most pronounced going forward but is still present in reverse . The kayak is quite loud underway . Not the quiet approach I wanted going to a fishing hole or stalking wildlife with my camera .

Everything you need to know to change the cassette bearings:

I'm not qualified to second-guess this mechanical design, but I believe the cassette should have a thrust bearing (or better yet, a right-angle gearbox). I put a stern-mounted trolling motor on my Mariner a couple of years ago & it is totally quiet at 50% speed or less, so I've almost stopped using my Propel drive for fishing. No matter what kind of propulsion is used, once you start seeing a good size bow wave (~2.5mph on a Mariner probably ~3.5mph on a Slayer), there will be some water noise.
