Hello everyone I'm back. Not sure if that's a good thing or not but hopefully to find a solution for me and future people. I have searched and seen a few things but I would like to pick and confirm my diagnosis before kicking out more BOAT (Break Out Another Thousand).
Any help would be greatly appreciated. Image is not my housing but a like kind.
I don't have a serial number its long gone on old valve covers that were trashed before I purchased the boat.
My Information:
1. Brand new rebuilt 5.7 pre vortec with fuel pump port but I closed it off with proper bracket and use an electric fuel pump mounted to front of motor so I'm thinking the motor is 1988 maybe 1986.
2. No T-Stat No Check balls they were removed (I think I need the check balls back in could maybe leave t-stat out)
3. New Lower unit Water pump
4. New motor water pump.
5. All water lines checked for clogs or collapse.
6. Intake gaskets have open front and rear ports (closed off small hole in metal lose off plate on intake gaskets)
7. Risers with laser temp 130ish both sides Temp
8. Exhaust manifolds 175ish Temp
9. Intake anywhere you hit it with laser 119 to 127 ish Temp
10. Laser temp at the thermostat housing beside the temp sensor 220 gauge reads 240
11. Large hose from motor water pump Hot as fire forgot the actual temp.
12. Hoses to Risers and risers cool to touch
13. Hoses to bottom of manifolds cool to touch
14. Inlet hose from out-drive cool to touch.
15. Good water flow out exhaust both sides at back boat and cool enough you could wash your hair in it and smell like exhaust
16. Rev engine over 2500 rpm it starts cooling back down.
17. run distance at 3000 rpm it heats back up to 200+ I shut down at 200 to try save the motor.
18. Stamp on the T-Stat housing is 47440 it has two hoses to Elbows, 2 hoses to exhaust manifold lowers and 1 hose to water pump.
