Hi Guys

Well much to my dissmay when I started the merc , water started coming out the manifold behind the carb. I pulled the manifold and found a crack . It is accessable. Have any of you people ever got a manifold welded? And if so what kind of luck have you had with it holding??

Ayuh,... Weldin' cast iron is usually followed by slatherin' the repair with epoxy paste,...
'cause the weldin' causes More crackin'...

Ya might as well skip the weldin' all together, 'n just slather it with epoxy...

'n Hopefully, it ain't cracked into the exhaust cavity...
