2006 GSX-R 600 Water pump o-ring

I am in the process of replacing the water pump. The new pump came with the o-ring already installed on it and the o-ring appears to be completed dry.

Could somebody please answer the following questions:

- Does the o-ring need to be removed to be lubricated also on the groove side? If so, what is best way of removing the o-ring without damaging it?

- I have some waterproof grease made by Maxima Racing Oils. Is this grease equivalent to Suzuki Super Grease "A", recommended by Suzuki for lubricating the o-ring in question?

Thanks
