rinsing the gear change on a DP-E

Unless you boat in very silty environments I cant think why you would want to. I'd sooner seal it with silicon than go about drilling large holes in it.
 
There are two open holes in the top of the cover, usually filled with a plastic blanking plug, I hear that some get lost after a service and not replaced and people carrying on without the plugs. So you could remove them and poke the hose there and just leave the plugs out.
 
Are you sure, the two holes enable access to bolts, if you look carefully you will see it is a blanking plug, take cover off to take a closer look.

I think you will be wasting your time trying to seal the cover, it will never be water tight. Once year during service I just remove the cover and rinse it and apply a coat of grease over the moving parts, as my boat sits in the water I do get a build up of silt and last year a few mussels, never caused any problems though.

Agreed but being water tight is not the point. It's to slow the passage of water through so as not to pick up any more silt once filled with water. In so saying it was a bit of a throwaway comment.
