Did you change all these items because you were having issues previously? Were the current exhaust shutters functioning or replaced during this time? Was there one missing? All hose connections good at the intake side of the raw water pump?

My engine temp started to rise before I did anything I checked the engine while running with a temperature gun found the issue was the gauge

Boat in the water or drive fully submerged, remove the hose off the pump, you want to place the hose into a bucket, start the engine for 15 seconds shut down the engine, measure the water in the bucket.
Be good, be happy, for tomorrow is promised to no man !

Like chief said, your measuring the volume of water the raw water pump puts out (outlet side of pump) Try a new t stat first.

The alfas have a spot where they collect salt, between the leg and the bell housing. I'm not sure if the bravos are the same or not. Otherwise you've done all the stuff I can think of.

Just talking with a friend of mine and he was having the same trouble he put thru hull fittings going to the pump and eliminated the pickup from the outdrive. He's very happy with the results. If it is the pickup from the outdrive going to the pump on the engine I might put the thru hull fittings in
