Thank you i ordered a owner's manual and it did not give locations of the pumps in the systems or valves so I'll try opening all the holes in the deck and do what you said thank you

This is the first year with this boat robalo 2120 1994 cc I have got a few manuals the information is vague I'm trying to winterize the boat only I do not know how many pumps this has and where they are there is a port to take a water hose in the rear on the left side I do not know what this is if there is any info anyone has with diagrams of where these operating systems are located on the boat would help me very much I have to winterize before I break something thanks
