Exhaust manifold hose configuration RAW water.

I need a diagram of the hose configuration for raw water cooled crusader mid to late 1960's. I have twin 350's in my 1966 Californian. Raw sea water cooled. Just manifolds with elbows at the ends. No risers etc. I replaced both manifolds, Thermostats, gaskets, hoses etc. Blew an exhaust gasket took things apart to fix and decided replacement was in order. Things kept looking pretty bad as I disassembled the manifolds. Better safe than sorry. Ive had the boat 4 years now and dont have the previous history except word of mouth. I put all the hoses back the way they came off however Id like to check the previous owner's work to make sure the hoses where correct to begin with. Have had no heating problems.
