1989 evinrude 140hp temp. problem

[hopy-d]

My son just bought a used boat that has a 1989 evinrude 140hp motor. We hooked up waster to it and ran it for a few minutes while checking it over. We had a small stream of water coming out of the small hose on the motor but we noticed that the two cylinders on the right side were cool and the cylinders on the left side were hot! Is this normal or do we have a problem? Does each bank have its own thermostat? What should we look for to solbe this problem?

Thank You for any help you can give us.

Yes each side has its own thermostats, you should start there.
