I have a 2006 VESS A6 with a 406 stroker and makes 540rwhp.

Recently, I was replacing the water pump and decided to go electric. Since then, and in no way connected to the water pump replacement, I had to replace the radiator thermo fans and motors and the radiator.

Last week, I was towing my ski boat and on the open road it was fine, water temp sitting around 95 degrees. However, when going through towns, she started heating up to over 100. And when I was backing it into the shed at home, it hit 118.

Prior to the water pump change, it has never gone over 100 degrees no matter what I was doing.

Do you think the electric water pump is letting me down or could it be something else.
