Oil Cooler Line Diameter
My stock oil cooler has 3/8" lines (6.2 MPI - twins in a 29' Fountain Fever).
I replaced the port cooler with one that has 250-300% more area (moved from 9 to 12" length, 2 to 3" diameter)
yet saw little difference in oil temps between port and starboard engines. Is it possible that the 3/8" lines
do not flow enough to take advantage of the larger cooler? The new cooler is set up for 1/2" lines.
I would love to hear comments from those who have actually changed oil line diameters.

I did on a big block and saw immediate difference but small blocks dont need or pump as much oil so not sure? In my case I am positive the bypass relief was opening and pump bypass was prob also opening and oil was never getting to the cooler, Smitty

BORGIE - Sorry, I now understand your comment. A high volume oil pump might make a difference, correct?
EZSTRIPER - I am leaning towards replacing all stock Mercury plumbing, remote filter adapter, block adapter, and lines with #10.

Thanks BORGIE
The new coolers are set up for 1/2" pipe plug. I'm not sure if that would be 8AN or 10AN lines. I will be looking into a block and remote filter adapters that will accept larger lines.
If someone has used a particular brand I would would love to hear about it.
