I took apart my pump housing tonight to swap out for the solas prop.

1. Should I install the solas prop that comes with the stage 2 kit (17/29) or go with an 18/31 that I also have.

2. I hear about this rubber piece that is supposed to come out and put in the new impeller. Is it an o-ring or something else? I have these 2 pieces already off the OEM impeller but not sure if its the right ones:

3. The grease that I am repacking, does it just go under the nose cone where the bearings are? or is there another location I need to back with grease?
