I need to replace all of the 8" x 15" opening ports on my 1983 Hunter 34. I have six of the Bomar/Gray replacement ports that have angled drains (G512-AD). The attached photo shows the new port sitting on a flat surface with the drain angled away to the left, approx 80 degrees. The black box to the right shows a 90 degree vertical reference. Seems that the ports I need to replace have straight drains, but I'm not 100% certain.I just spoke with a sales rep at Pompanette/Bomar/Gray and they tell me they do not stock the 8" x 15" replacements with a straight drain. I'm not too keen to start ripping the old ports out until I'm certain I have the correct replacement. Any experience with this? Suggestions? Thanks, Gary
