The lake temps now are in the low 40's.
All I am saying is by watching the smartcraft temp fluctuate for 16 days on the lake, I believe you are better off waiting to accelerate when the t'stats are closed.
I can gaurantee that my engine was properly warmed, the t'stats were not sticking and there was no debri. I can also attest that I watch my smartcraft temps religiously.
While idling my temps fluctuate. You can see when the t'stats open and when they close by the fluctuation in temps. There is a distinct difference in temp while idling. Temps even out while on plane but not while idling in cold water.
I believe part of cold seize problem can be attributed to that rush of cold water hitting the cylinder wall when the tstat and poppit are open at the same time under acceleration.
Seems like a high percent of cold seize issues have occurred right after acceleration and I believe what I stated above may be a contributing factor.
Anyway, I will be waiting to give her juice until I see the t'stats close.
