[C38] engine temp

[Steve Smolinske]

fyi
 
as a follow up to earlier discussions on engine cooling, I replaced the 2" x 16" heat exchanger with a 3 x17 and dropped 30 degrees off of my normal operating temp.  went from 190 to 160 under way. With the larger exchanger I was also able to step up to 5/8 from 1/2 hose from the raw water pump to the exchanger.  Im amazed at how much smoother, quieter and less labored the engine sounds now.
