starboard exhaust manifold getting hot!!!
 

Just put a NEW 5.7L long block in my boat and i went through everything cleaned it and all. I started it and the starboard exhaust manifold and heat riser was hotter than the port side. Any ideas???????
Its a 2003 Mariah sx20 with a 5.7L 2bbl carb, performer intake.

Sounds like either a blockage in one of the water hoses, or you need a new impeller in your water pump.
