 Can you find a larger pulley for that saw motor Bill. I would like to
 know at what RPM the Mazda pump starts cavitating. I'll pop for the cost.
 What size shaft is it? We can order one from McMaster Carr.

 Paul Lamar

The motor has a 5/8" shaft, with a keyway.

By the way, it weighs 42 pounds.

OK Bill I will see what I can do. What is the current max diameter
and what max diameter can you handle?
I see an 8 inch 4L(A) section belt Zinc die cast 5/8th bore.
We can get a pressed steel up to 18 inch.
