Hurth BW50 Transmission Question

I plan to replace the seal and gasket on the shift control on my HBW 50 transmission. I have been told that it is an easy job. Is there anything that I should be aware of such as do not move the position of the shift control? I have not launched my boat for the season yet.

Thanks
