Default HP 500 (stock) overheating

Need some help! 38' Fountain twin hp500's. The one engine is heating up. Just replaced gimbles, impellers, and the hoses from the drives to the engines. Everything seems to check out. Any suggestions on where to start?

If you can't track it down use a heat gun to find temp and check it aganist gauge, I just had to replace my water temp gage 2001 Fountain, that was after replacing everything twice

You did use the hard wall hose for the drive-seapump inlet correct?
Were the old impellors complete when removed? If not, removed broken impellor blades from PS cooler?
I second the double checking correct hose orientation and T-stat operation.

Pinched supply hose from the new gimble install?
Does the hot running motor have water pressure?
