Mine has had that difference since I owned the boat in 2021. At this point, I'm just watching for changes.Ok so interesting...
I am seeing @2300 rpm 147 port & 140 starboard running for 30 minutes in 80 degree sea water. Both my engine coolants are at 174. So I was thinking I might pull my trans cooler out and inspect / flush on the bench. Being it is the lowest cooler in the salt water loop I am thinking more prone to build up and debris. It just bugs me the almost 10 degree difference.
