I had a 2001-310 and the port wiper motor was accessible through the light fixture in the ceiling in the galley . Remove the fixture and you can see the motor
I had a 370EC years ago and SR put the access through a removable panel "inside" the cabinet in the head. Just saying that SR will put the access anywhere they can.
Thank you all for the tips ! I will check them out as soon as the shrink wrap is off in the spring . Tom , I know you don’t have that problem as you are boating in a warm climate year round! Thanks, Pete
