2005 320 DA port engine (rebuilt 2 years ago) running warmer

Thank you and off now to see if I can get this sucker off and replaced today! I tossed out an old pump and wish I had it now just to see it for orientation purposes

All issues have been resolved because my exhaust manifolds were clogged and not moving water efficiently. replaced all manifolds risers and elbows on both motors to even out my worries and baseline the histories. The boat is running as well as day I bought in 2007.

Your saying that your 2 year old exhaust manifolds were done and needed replacing ?

I had a similar situation. Replaced the entire pump as it is brass and tends to wear. However didn't solve the problem. I had to "descale" the motor. Essentially flush it out. Once I did the temp returned to normal. For what it's worth.
