1999 DF70 Head

[vrodrig]

Hello folks, like all salt water outboards corrosion happens! I have removed the head from the engine due to water entering the cylinders, took it to the local machine shop for repairs and I cant find specs in my manual for Head Thickness. The machinist looked for specs through the Engine Re-builders Association and there were none available. I'm seeking limits for shaving/resurfacing the head. Might any of you have this info available or is there a specific site or book I can look for?

Thanks!
