After the discussion of using gear oil instead of grease for the propel unit , I didn’t hesitate to switch . I went to Wal-Mart and purchased a quart of synthetic blend 75w-90 differential oil and used 8 oz ( total ) for the upper and lower gear boxes . I’ve never had water in my gear box and saw no reason it would be a problem now . After putting it in , I went to the lake for a test . The temperature was 50 and the water temperature was 54 . I used a fish finder with gps for testing . At 2.5 to 3.3 mph it was effortless ( litterly just going through the motions ) like on an Exercycle . At 3.5 mph there was enough effort to say it was sustainable for a couple of hours nonstop without being too tired . At 4 mph I would say 15 minutes would be the most I could do . My top speed was 4.6 mph which is a sprint in the propel 13 and wouldn’t be doable for more than a couple of minutes . Before using the gear oil it felt like a sprint uphill pulling a sled to go 4 mph and 30 minutes at 3.5 mph left me tired .
My kayak had my fishing gear which weighs about 25 lbs and me at 185 . Using a gps before the gear oil it was difficult to tweak a speed of 4 mph . Now 4.6 mph is attainable without all out effort . The groaning sound is barely there on maximum efforts so that also is an improvement . My impression is that oil is what the propel unit needs and not the grease that comes off and makes the effort get greater and sound get louder as mileage increases .

So what is the process to fill up the drive with oil?

Got back from my first trip using 75 90w gear oil in the lower cartridge, upper + lower gear boxes and so far i'm impressed with the results. The drive is much smoother and more importantly much quieter. I had just replaced the cartridge seal and all three cartridge bearings so that may have also added to some of the smoothness. Water temperature was 47 degrees and I didn't notice any more resistance with the gear oil over the finishline grease. I will continue to update as one trip isn't enough time to come to an conclusions for it long term performance.

I did mine probably 20+ hours ago and it is nothing but better. I used gear oil on the lower and Lucas Marine Grease on the top. It's time to inspect the top but it feels great, smooth, quiet and no leaks. I would go, and still might, with adding gear oil to the top but there has to be grease too. There is certainly a passage between the upper and lower. I had my drive flipped around once while I was working on it and the gear oil traveled into the upper - it was upside down.
I've had my share of drive problems. This is my third drive. First came with no grease, second had saltwater intrusion, both in the first usage period - before I needed to open it the first time to lube and inspect. This one is much mo betta especially with this lube method.
