Pump Motor from 115V to 230V

[Rick Carone]

Hey, I have a Speck E90-I pump motor (AO Smith p/n 7-193530-20) that operates on 115V only. I'm wondering if there's a way to rewire it for 230V. Unlike my previous dual-voltage Speck motor, this one doesn’t have a capacitor. The internal wiring setup includes terminal 1 with a yellow/black wire (L1), no connection on terminal 2, terminal 3 is empty, terminal 4 has a red wire, terminal 5 has yellow and blue wires, and terminal 6 has a white wire. Is it possible to convert this to 230V?

Should have a diagram on label or terminal cover. Should have both voltages listed. Take a pic of the motor label. Pt number doesn't help.
