I asked the guys on the storefront on this site. Just send a request and they'll answer you. Here's what they told me when I asked and I have the same boat model and year as you. Mine doesn't leak yet but the gasket is gone and one lift and lock is broken off.

Hi Roy -
You can view that hatch by clicking the link below. It is our item number 983736 which includes the trim ring and screen.

Below are all the specific measurements of that hatch.
Hatch Opening
16 5/16" X 16 6/16
Hole Cutout
16 7/8" X 16 7/8"
O.D. of Deck Flange
18 7/8" X 18 7/8"
O.D of Hatch Lid
19 1/8" X 19 3/8"
Right now hatches are being constructed after order so it takes about 18 - 25 days for a Bomar hatch to ship. If we can get them to make them any faster - we certainly will.
Let us know if you have any further questions.
Kindest regards,
Bly Berken
