Yamaha 70hp outboard engine block compatibility

fishaz

Hi guys, I'm needing to replace the engine block on my 88 Yamaha 70hp outboard boat motor. I'm having a tremendous difficulty finding the exact block in any kind of decent condition. I know that the block were all the same block from 84 to 98. I found a good looking block from a 2002 70hp. It looks to be identical. Does anyone know if it is compatible with the parts that I have?

  I wish that people that post would say fresh or saltwater where the boat is used.If
fresh water I could see the repairs.Salt water no way,your 10years past expected
life of the average engine.
