Re: Can a dry exhaust be routed through the prop exhaust route
I guess im miss guiding everyone with the way im asking my question and im sorry for that.
-Freshwater only
-Pics were to display design versus specific items to be used. I know the first pic is of BBC headers and i have SBC
-NO chrome, ceramic coating at min.
-Goal is more weight saving purposes
-Dont want open end exhaust sound (i guess full dry exhaust with thru-hull design)
-Never stated want to go fast.
Goal, i will be building a fresh 5.7L stock bottom end, maybe new cam, now instead of iron heads/intake/exhaust manifold im looking into aluminum (for weight saving purposes, NOT specific for HP/go fast purposes)
Bond-o: When you refer to water jacket, what exactly makes it water jackets? Is the design a tube within a tube? So the otter tube allows water to flow around the inner tube (gases) hence cooling the exhaust and never allowing water to flow into exhaust port on the head. If this correct then this explains why the cost of aftermarket heads are what they are because of the extra work to build them. From the pictures you can not see the tube within the tube design therefor misleading me into a different design of this pic
Most after market affordable manifolds follow this design
http://www.glmmarine.com/manifolds/images/Manifolds_Flyer_Web.pdf which i was under the impression is "wet-exhaust design"
So with the first and last pic, is this a tube with a tube design? If not how does the water flow within the design?
I understand weight difference is min but im exploring the area of saving maybe 10% weight (passenger capacity) not overall boat weight, thats like one less person in the boat.
I have some money saved up and plan on putting some into the boat, hence the fresh rebuild engine and i dont mind spending some money on the extras (aluminum heads/intake) easy enough but now exploring the exhaust manifold idea. Now from what i have learned so far is my idea of how the wet/dry systems work is wrong so thank you for pointing that out now i trying to correct myself and learn how the differences work, how does the water flow with the setup on the pic above (BBC style setup).
