This engine had a 1-1/8" x 3-5/32" shaft. The CV25S- 69525 is no longer available. You may be able to use the Cv730s-0029 engine which has the same mounting and shaft diameter. The shaft is longer but it is not hardened steel and can be cut down. It is drilled and tapped an 1" deep. There may be minor changes but parts should be interchangeable from your old engine.
