Indmar 350 MCX hose connections

I'm in a ProStar 190 boat share too, and that boat has blanking plates at the transmission end of the manifolds. I'll get some photos up today. I think maybe the previous owner has got a bit carried away!

Bouyhead as mines a salt water series the intake manifold and cylinder heads are cooled with antifreeze (indirect), so that coolant doesn't exit via the exhaust manifolds. I think it's just the raw water that goes into the manifolds. I'll get some pics uploaded.

Attached is a picture of the exhaust riser, showing the two fittings for water on the riser (transmission end and water pump end). Personally I think the transmission end needs blanking off (as raw water is fed from the water pump end and exits into the exhaust itself. What do you guys think?

Ah I think that is what someone referred to as the drain pipe but anyway it should be connected to the manifold on the opposite side so it is essentially a balance pipe that connects the 2 manifolds together, this pipe usually has a connector halfway along it that can be easily removed so that the manifolds can be drained hence the term drain pipe.

I went to look at actual boat yesterday and found the above mentioned balancing pipe that goes between the manifolds. Seemed to be way longer than needed (about 6 ft), I'm guessing it doesn't need to be that long.

Usually runs over the gearbox so that it makes it easier to drain
