What should I use to lubricate the bowl bearings? 90W gear oil or a good marine grease? Which would be better? I don't want to water lubricate because the river it will be run in is too silty I think. The water is always brown, especially in the spring, and it runs through a large portion of the state and picks up a lot of junk along the way. But if I did water lubricate, can it be done with a bowl stuffer installed? Thank you.
