I noticed that my starboard manifold and riser temp definitely feels hotter than my port manifold and riser temp. I can place my hands on manifold and risers on starboard side but not as long as I can on the cooler port side. Someone recommended I try the bucket test that involves disconnecting the hoses that go into manifold, placing buckets under them and start engine to see what bucket fills up first. Surprisingly the starboard side (hotter side) filled up twice and fast as colder side. I would have thought the opposite would have occurred. Motor is a single 7.4 MPI, 425 hours, risers and elbows replaced 4 years ago, RWC and in fresh water. All water pumps new. Engine temp runs normally between 165-175* I did not use heat gun to see what manifold and riser temps are what the differences are. Hope to do that soon. Can anyone comment on this?
