Chaparral Vortex 203...Where's my drain plug?

[JetBoat Geo]

Not boat engine savvy at all, please help!

I need to put fresh coolant in my starboard engine, as the coolant was so low last time out we had to put some fresh water in the reservoir to stop from overheating...not sure why it was so low, hope I don't have a leak!

So my question...where's the drain plug? Also, anything common with these motors that I need to check that might be causing this problem? I just recently got it back from the marina after they put in a new O2 sensor and (2) new catalytic converters. Thanks in advance!!
(I have a 2016 Vortex 203 w/twin 150s.)

If any of this sounds stupid or doesn't make sense...please see line 1.

The drain plug is on the cooling plate. It’s a 3/16 hex or Allen nut. The white seal around it is waterproof/ removable loctite. Don’t know that number off hand but if you can’t find let me know. I have it in my boat box of tools somewhere. But just tighten the Allen nut first. Or really first tighten the tubes connected to the antifreeze container. Might have a leak there. The picture here is from someone who has a slow leak and just tightening the nut fixed his issues. Good luck

Awesome, Thanks! Pretty easy when you know where to look!! Do I need to do anything special to drain it, or just be on an incline and pop the coolant reservoir caps?
