MerCruiser 3.0 blue drain hoses connection

Hello,

I can't find a good picture of how these hoses should be connected. Could anybody tell me if I did it right?

Thank You.

Looks tight to me, one for the block drain, the other for the manifold drain.

Agreed - I just checked mine (same engine) and it looks right. One blue line (as Don says) goes to the block, one to the manifold drain (that's the plastic (it's cheap- be careful!) fitting coming out the bottom of the manifold. The black line goes from the other fitting around the back and upto a connection into the line going into the T-stat.

PN...Do you know what the last black line for?
