I can't figure out what to do to remedy this. Here's what I know:
--Starboard engine seems to run at the right temp(just over 160).
--Port engine runs about the same, but will creep up approximately 20 degrees while running slow(under 1000 rpm). Never 'overheats', whether slow or on plane.
--Port engine cools to same indicated temp as starboard when run above 1100-1200 rpm.
--Both exhausts appear steamy/smoky(hot). Port exhaust is hotter than starboard, no matter what the gages indicate.
--Both engines have brand new impellers.
--When I am running I have taken temp readings with a laser thermometer, and almost every surface is 20 degrees hotter on port engine.
--Planning to change thermostats on both motors today, but hard to believe they will change anything based on what I can tell.
--Both engines run very well, with only 240 hours on each.
--I am wondering if I have bad exhaust risers? Trying to rule everything out before tackling them...
Hoping someone can shed some light on these issues so I can make the right changes. I am sure the exhaust should not be steamy when it's Summertime and the air and water is warm. Looking forward to your input!
Thanks in advance.
