No just saying my T stat is still kicking and all is well running at 160*
My Engine loves the relief and non existence gate valve setup
My boat is still Bass boat Green and has a Damn Ford in it but still with all that bitches still wanna ride in it, get wet and drink Rocky Mountain kool-Aid!!!
Going to state it one more time and then I'll leave it alone.
Your set up, without exhaust logs or a recirculating pump, has a gigantic temperature differential from the front two cylinder walls to the front two cylinder combustion chambers.
Running in say 60°F water, with a 160°F outlet temp, a 100°F difference.
I never feel silly comfortable with more than a 60°F delta within the block.
I'm OK with the relief valve, it shouldn't be needed, but I'm OK with it. But the 160°F argument is silly.
The only ways I recommend running a thermostat package is an I/O type (absolutely the best) with a block mounted water pump, or with logs/preheater. This way the water entering the block is much warmer and close to the desired temp.
This reasoning is not made up gobblygoop. It is the same reason you don't put cold water in an overheated car, cold shock will break stuff.
If you were to put in a colder thermostat, like a 120°F, it would be much much safer.
You have to realize, it's OK to have such a huge delta at idle, because there is virtually zero load, but yours does it at WFO. Let's say 45hp per hole. The rear cylinders might survive, but the fronts won't.
Visualize a 60-70° cylinder wall with a 160° cylinder head. No engine in the world had that design criteria in mind. The water goes all the way through the block before it enters the head at the rear, same as a Chevy and a Mopar. So technically your still running a stone cold motor, but with extreme hot spots. That water doesn't move very fast, and the temperature won't be linear nor homogeneous. Wherever the water is slowest, it will be the hottest, may even turn to flash steam (aka steam pockets). This causes all sorts of carnage.
This is exactly why I set the boats up the way I do, they can have a cold leaving temp at wide open throttle, but warm it up at idle to heat the oil and bring things to temp.
Not sure where you and I got started on the pissing match, but I'm over it. Let's go boating and have a few beers.
Everybody has their own way of doing stuff, but when it comes to a forum with rookies lurking about, I try my best to put the information out there, it's up to them to decide of they want to follow free Internet advice.
Have a marvelous day and hope to see you on the water soon.
Your friendly neighborhood GT Jets.
