Hello,
I have one of those typical cracks on my old 93 DT150 lower unit. It runs from the end of the exhaust area inwards about 3" . Following advice that I've read in older threads here, tomorrow I am going to drill a 1/8" hole at the start of the crack. What I am wondering is what is inside the lower unit at that point. I looked at the FSM diagrams but it isn't real clear how far inwards anything "important" starts. Do I need to be hypersensitive to how deep I am drilling, when 3 or 4" in from the exhaust flange?
Thanks in advance,
-E
