Hey guys excuse me for the dumb question, But I have never owned a boat before, Im currently deployed and my wife just bought one for our family. Now this leads me to a couple concerns obviously. Its a 1996 Glastron GS 215 with a 5.7l Mercruiser and alpha one outdrive. Thats all I really know. The guy says the motor is solid and he has it winterized. I already know the interior needs some help and Im willing to accomplish that as long as the boat runs. We got it for a good price (in my eyes). But something that concerns me. below is a picture that my wife said was leaking out water. Im sure its a drain plug, but he never gave us a plug for it. Heres my questions. The day we picked up the boat it was raining hard and he only had mooring covers on the boat. Is this water draining out of the engine compartment from the rain and him hosing out the boat? Or is this something more indepth then that. If this truely is a drain plug and should have a plug in it how hard is it to change this part? Is it just those 3 screws?thanks for any input. Im sure I will have more questions as I go along on this journey
