Yeah, it's time consuming and tedious. We did two of our eight last year when we replaced the screens (30 years old). "Have patience, my friend," a
beer or two for purely medicinal reasons (i.e., your thumb!!!

) never hurts - makes time fly by.
Otherwise, the
ports are just great. I like them better than the reports about "Leaky Lewmars."
Good luck.
Oh, and reread the RTFM, too. Never hurts. Make sure the channels are clean, clean, clean.
