1990 Volvo Penta 3.0 drain plug locations

[fishr]

Hi all new here and new to the bigger than an aluminum boat lifestyle but I have a 1990 Glastron with a VP 3.0 that I’m going to winterize, I have the manual but it does not say the location of the water drain plugs to open? I’ve looked and felt all over.
Any help on the location and how many would be greatly appreciated.
Thank You!

left side of block, near back, down about 2" above the oil pan, thermostat housing, the manifold drain, power steering drain if you have it, big radiator hose and the feed line to the raw water pump

That is one blurry pic, but do think it might be a drain plug. If it is, I would get the thig off and replace with new

Yeah that is a screenshot of a video I took. Shoved my phone down in the motor area trying to see where the plugs were at. Only found that 1

Hey Scott where is the manifold drain?
