I'm hoping this is not a cracked block.. is there any tested to do to confirm if it a cracked block or not?

Did it leak before you changed the gaskets? Was there any seals inside that could have been changed? Ie the bottom crankshaft seal?

yes it leaked before i replaced it and i didn't see to much else in there that could of leaked there was a bottom crankshaft seal but the shaft had no oil on it the oil was actually mixing with the water near the exhaust and water ports

You may have to take off the power head again. And the adapter plate. And do an inspection of the surfaces that are around the water jackets. Use a good straight edge look for warping. You could probably use a good crankcase sealer like they use on motorcycle cases to seal up the surfaces on both sides of the gasket around the water jackets . A gòod product Yamaha has is called yamabond. If they still make it. It's for motorcycle cases
