Starboard riser a lot hotter but temp gauge reads normal

Just did my annual preventative maintenance and also replaced my y-pipe. Boat is running great, temperature at the dash gauge is perfect at 145 degrees, and performance is excellent. Impeller is brand new. On the muffs, water comes out both sides of the transom exhaust, port side is almost like a hose, starboard is fairly normal and consistent with what I usually get. Port side is warm, starboard side extremely hot. I figured it may be the muffs, but I had the boat in the water today and got the same result.

Should I be worried?

Jack up the port side of your trailer and more water will come out the starboard side. Highest riser is always warmer
