replacement pump motor

Greetings,
I’m replacing the motor for a Hayward Power-Flo II Pump for a spa…
The AOSmithCentury label does not match recent ones – no model #.  It says:
1081 Pool Pump Duty SP1510-Z-1-XE.  Also:
1HP, SF100, amps13.8, rpm3450, type SP, Part 7 184878-22, serial BW1-05, formPHM.
The frame throws me, W48Y, not just 48Y.  It is also thru bolt. 
Any suggestions?

Hi Bobbo9,

You will require this BN25 Replacement Motor as well as this Power Flo II Seal Kit

Thank You

Patrick
