Thanks for the reply, it would be the 2 drains located on either side of where the emergency tiller inserts at the rear of the cockpit and behind the pedestal.
I would agree it would be best to pull them and measure myself. It's on my punch list to do tomorrow morning before it get hot and humid. Wish we would catch a breather on the heat and humidity.
I'll post what I measure on mine and what I ended up doing.
Thanks,
Glenn
