I have a 2007 Suzuki DF115hp

While trying to attach a new water indicator tube to the water outlet, the tube accidentally dropped into the opening at the exhaust and water tubes.

I have two questions.
.
1. As the connecting "screws are at the end of a "long tunnel" Which screwdriver will undo the outer casing so as to gain access to the "dropped tube" . Are the screws flathead or phillips , or is it a bolt, if so what size of bolt head. Also Is it hard to take the outer casing off ?

2. What is at the bottom of the "gap" if I was to leave the loose tube where it is, will it interfere with any operation of the engine. ?

I would be grateful of any advice as to what to do.
Thank you
