How can I identify a cracked block?

[jasonbrodsky]

I just bought a Mantray with a 4.3L Mercruiser.. The previous owner said it had water in the oil and a cracked block. The motor looks clean. The boat has also sat for 2 years. Where should I start first? Are there any maintenance manuals out there?
