Aaron, I agree with joe...Take out the t-stat and see how it runs...if you don't totally tear apart the gasket in the process, you can just bolt the housing back on for the test, and maybe use some Permatex (#3 in the can with a brush) to help seal the gasket area and report back.
200°F is not too hot, but you are running out of margin much past that..most RWC'd motors are 150-170°F.

Do you already have the bypass valve on the 1/2" hose from the side plate that goes into the stbd side of the t-stat housing? You can simulate a valve (closing the flow in the bypass hose) to force the water up thru the block and t-stat housing with a pair of needle nose vice grips or similar tool.
