Hello. This is my first thread so bear with me
I have a Mercruiser 350 5.7 liters V8 (1990-1995) with a Volvo penta outdrive 270 or 290.
I have made a full renovation of the engine with new head gaskets, and a lot of new parts.
After assembly of the engine I have run into a big problem.
The first test ride ended up stranding me on the ocean because the cooling hose blew.
After I changed the hose i have noticed that there isn't any flow in the seawater filter. The impeller works fine, as it pumps a good flow of seawater.
I have learned that there are something called a warm manifold system, and a cold manifold system. I believe I have the cold system.

I have the gaskets with the restricted holes between the elbow and exhaust manifold. (worked fine before the renovation).
I have also tried to run freshwater from a hose through the system, but it won't "take it" through..
Does anyone have an idea of why the engine overheats and there is no flow of coolingwater?
Regards Mikael
