I wasn't the guy who said that stuff gets there but cooler material and inner line material can all age, I prefer to have my filter be the last thing before entering block, again why not? Never had one issue and many run this way actually

I have the same risers, and noticed my water pressure was a bit high as well. My o2 sensor was getting a little wet as well.
The water outlet holes are drilled in the inside diameter of the pipe allowing the water to splash against the wall on the opposite side.
I elongated the holes toward the outlet end of the pipe. Water pressure went down. o2 sensor is no longer getting wet. Pipes are still cool....

In my photo the line from the block/ oil pan is going directly to the filter, then to the oil cooler , out of the oil cooler and then back to the block feeding the bearings etc.
The filter is the first thing the oil goes through on my engine which Mercury set up. I did not change a thing. If you install a filter after the oil cooler then you are not protecting the cooler, letting the pan oil go through the cooler and then to the filter??? something not right there. I would check the arrow directions

I'll keep mine where Mercruiser designed it to be. This way i know clean oil is going thru my cooler and to my bearings.

We seem to be getting off the subject here..Back to oil temps...I made custom fittings between the exhaust manifolds and the risers allowing me to dump some water overboard thru 2 fittings on each side of the boat. The hose size was 3/8". When that setup was connected my oil temp was 20 degrees less and my water pressure was 5-6 lbs less. reason being, the relief of water pressure allows the water to go thru the cooler faster removing more heat BUT...repeat...My Stainless risers are running a bit warmer at idle due to the reduction of water going thru them...so my question is. Is it ok for the SS risers to run warm at idle??...If so i will re-install the dump lines
