So I just got this 86 searay Seville with a mercruiser 140/3.0, guy said it ran last fall but during seasonal maintenance the mechanic found a blown head gasket. He didnt want to touch it anymore so sold it cheap. After inspecting block, head, and cylinder walls it didnt appear to have any damage or warping, got it all back together and it ran fine... UNTIL.. the thermostat opens, then it shoots water out of the valve cover hose, at like gallons per minute rate. My question is, do I have a warped/cracked head, bad gasket. Or cracked block? Still has good oil pressure, temp, and runs fine even when water comes, although I stop it immediately of coarse. New ignition system, gaskets, and oil/filter. Are cracked heads common or warped more likely? How about block? Any other possibilities? Thanks in advance.
