I'll skip the sad, long story of my engine's past..... Bottom line is I have small (1-2"), thin cracks on both sides of the block a few inches above the drain plugs that leak very slowly. I will not be replacing the block so I want to try to fix as best i can. I read A LOT here and elsewhere on this and many feel there is a decent chance the fix will last - maybe longer than my 23 year old boat. the key seems to be to sand/grind then clean very well as prep. Then the patch.
My question is, what to patch with? I read some have successfully used JB Weld some say Marine Tex (epoxy). My mechanic (not the one who caused the crack, btw) says he'd use marine tex because it does well at higher temps.
What do folks think here? JB Weld? marine Tex? other? IF "other" please let me know where I can but it if it's a less common product.
Thanks as always.
