Well now I'm completely confused. 1/2 Ball valve brought the temp down to about 165-170. Great says me. So what happens when the valve goes completely closed to route all water through the side plate ..... wait for it.... Nothing.
Temps did not move.
The WG Side Plate side is clean , the oval passages in the block (manifold side) are clean. I've done a pressure wash and acid bath. Ample water is batching out the exhaust. It seems like a fine amount. The manifold was pressure tested and hosed out.
I now have a laser temp gun. It seems the next step is to pull the thermostat out and see where this lands.
Also but different I have an oil pressure problem. 3 qt of 10 -30 went in right before launch. Over winter there was a MMO rich batch in there. It may be the 10 -30 has mixed with the MMO left over and made the viscosity too thin. It's hard to tell what's on the dip stick. More telling is the pressure. Idle, no load, pressure reaches 40 PSI. Increasing rpm, the pressure goes to 60. Under load and running hard (testing temps) the pressure went past 60 and stopped around 70. This is all bad, right? The BOOK says it should level off back down at 40. That's no where near what I"M seeing. The accessory drive sounds loud to me. I'm having a perspective problem. I only know my engine and have lost reference.
The Pressure Sending unit is new. The gauge is new to match the sender. I have never adjusted the Oil Pressure in this motor. I guess I need to learn that part.
Plan to change the oil. Thinking 15-40
I just want this to go back to simple. It's not been simple since I back flooded the engine in a very, very rough sailing trip.
Thank you to all involved.
