bearing seized

Hi Guys,
I have a 1987 70 hp and have disassembled it. The bearings on the crank need to be replaced. I removed the ring but can not seem to remove the bearing.
I can not see a seam. I dont know what to do now.
Any suggestions?
Thanks
Ron

Only the top and bottom main bearings can be replaced on that engine, it uses a pressed crankshaft and is sold as an assemble including rods, rod brg and center main brgs.

Thank You Sir,
no wonder I cound not see the seem.
