crack in crankcase 2-stroke 70tlrw

[jthoneycutt]

I have a hairline crack in my crackcase slowly leaking water as engine heats up. location is on backside of crankcase running from left to right about 1 inch long. lower section of crankcase. Is repair possible without replacing crankcase. How would I repair it. If sent to shop for repair about how much would it cost??? This is a 1998 yamaha 2-stroke. Help is appreciated.
Thanks....John

Need to take it to dealer and let them look at it to see if could be repaired, would depend on where the leak is.
