I was first concerned if I got the right one, but after comparing measurements it was the right one, though the description threw me off a bit since the actual measurement is 2 3/8, but it all worked out. I read the reviews from previous customers about the wiring and do agree, the specs on the site are different than how the wiring harness on this one came. Taking their reviews into perspective, I hooked it up and had no problems. The spa pump is working great!

The person I talked with while placing my order was very helpful. I placed my order late on a Friday afternoon. The pump arrived early on Tuesday morning. It should come with a bold faced caution to double check the wiring diagram. I too blew two fuses at $10 a piece before I discovered the posts on the new motor were different then they were on the old one.

The pump arrived quickly and in good condition. Disconnected the old pump and connected the new pump. I followed the included wiring directions which were the same as the old pump. Blew the main circuit board fuse (30 amps). Thinking I must not have cleared the wiring cover, I removed it and got another fuse ($10 bucks). Blew that fuse too. Went to another spa place, got another $10 fuse and the guy there said "I know what is wrong". He said it happened to him too & he has over 35 years of experience. .. more
