Aquatic 8078 MOTOR ITT Marlow Gemini Plus R75A-C

Drop in replacement just as described. I had to go check out the whirley bros website for info on the air switch.

Fit perfectly, easy to change out. Works great.

Flood recovery

Our 30-year old spa pump and heater were destroyed by flooding from Hurricane Helene. Trips to plumbing supply shops and pool/spa outfits were fruitless, but then I found Whirley Bros. They answered my questions and guaranteed the new pump would match the form, fit and function of the old. I ordered one, thinking "they're gonna get me on shipping", nope, if you're not in a hurry, free is an option. I had to pull the guts out of the heater and pot the openings with waterproof epoxy and silicone, but after almost a year, we have a whirlpool spa again! Great company.
