Note: A 115v motor that uses a 1 HP Impeller would show about 11-12.0 Amps on high speed a 230V motor would show about 8.0 Amps on High. See chart below for other Horsepowers. Do Not choose a Larger Impeller thinking that it will make your Hot Tub Stronger it will only damage the Motor and make it run hot on high speed. To determine the HP refer to the chart below.. The difference between a 48 or 56 Frame wet end is the spacing of the Motor Thru bolts. The 48 Frame will be 3 5/8" between or 5 3/16" in a X Pattern and have a 1/4" Bolt Head and the 56 Frame will be 4 1/8" Between or 5 3/4" in a X Pattern and have a 5/16" Bolt Head.
