I have a 2001 Mercruiser 5.0. I have noticed that the starboard manifold is SIGNIFICANTLY hotter then the port manifold after the engine has been running. The temperature gauge never goes above about 175. Is this normal? It might have been this way since I bought it (used). Thanks in advance for any input.
