Are you saying the engine is shot after 225 hours, or is there a hard
calendar time life on the engine?

For US standard type certificate aiplanes operating under part 91
there is no mandatory TBO or calendar life limit on the engine.
Manufacturers may recommend a TBO or life limit but it's only a
recommendation. For example, Lycoming may say an O-360 is only good
for 12 years or 2000 hours between overhauls but I know many engines
remain in service much longer than that.
