I ordered new gasket kit that comes with new bolts and nuts so yes I will be replacing all gasketsseparating those elbows means you have to have new O rings right?

I have a few things to do to finish removal of the riser system from the manifold-Not much work to do before changing everything but just can't get to the boat now until Saturday. Still have not received the other manifold yet so I will just have to wait.

Congrats on the new boat. This is generally a straight forward remove and replace.
As for the Fresh water cooling, you do not want to convert old blocks to freshwater cooling.
1. If the boat has ever been in Salt Water, the residual Salt will react with the antifreeze and gel. Also Fresh Water Cooled boast generally run at a higher temperature (Different thermostat, 165 vs. 140) Again, any salt residue may crystalize in the engine block with the higher temps.
If the boat was always in Freshwater, then you don't end up changing your manifolds and risers often anyway as the fresh water is not nearly as corrosive and the expense advantage is negligible. With FW Cooling, you still have to winterize the water system, it's just a smaller amount to winterize. Winterization on inboards is generally very easy. Provide antifreeze to your intake hose and pump it through by running the engine. Then fog through the carb.
