Guardian mode - AGAIN!

Well I had the engine scanned and my sea water temp sensor was bad. Replaced and it seemed to fix my problem. Out last night, ran 10 mins on a no wake river (temp at 160*). Got on plane, ran 5 mins at 165* then quickly moved to 170* and got a "block pressure alarm". Took the boat back in and the 10 min ride on the river temp at 160*. Back at the dock while the boat is idling at 165*. Took the following temp readings:

Thermostat housing: 165*
Starboard Riser: 89*
Starboard Manifold: 172*
Port Riser: 92*
Port Manifold: 168*

Are these numbers OK? What would cause a block pressure alarm? When I had the boat scanned they could not read block pressure
