Hi,
I hope this is ok to post here.
I'm CAD modelling the Chris Craft KBL engine of my -53 Riviera.
What I don't fully understand how the cooling water flows.
I have a collection of images from a KBL rebuild and I can of course refer to my engine but I'm still not getting it all.
Here is what I think but I'm not sure this is correct:
The water comes from the water pump through the oil cooler and enters the exhaust manifold at bottom side at the aft end.
Then it is not clear what happens.
It appears there are four axial channels / passages in the exhaust manifold.
The water flows along some of these channels in the manifold to the flywheel end and exits the manifold via a port at the top end of the end flange.
From there it goes to the cylinder head and from the cylinder head it flows through orifices between the cylinders into the cylinder block.
And then via a different set of orifices back to the cylinder head.
From the cylinder head the water finally exits via elongated orifices over the exhaust ports through the engine block to the exhaust ports on the cylinder block and from there to the manifold exhaust passage and then to the exit elbow.
But it looks like there is a water channel on the top of the exhaust elbow which exits into the exhaust pipe and where does that water come from?
