Hey guys I just got me a new boat project and I think it's a great candidate for a through hull exhaust, but I don't really know all that much about installing them other than the hour or so research I just did. So...any advice on where to get the parts, installation, or so on. The motor I am dropping in is a 1979 Merc 5.7L 350 ci with the end style risers. Does iboats sell the kit? How much would one estimate, parts only, it would cost to do such a thing?
