Customer Reviews
Marty Smith
While in Guatemala for hurricane season, AC pump started failing. Thank you for the extra effort to search the warehouse and find the last one! Arrived in a week and we are back to cool air!
Mariana Pezzulo
We have been replacing the March air cooled for this model and has worked fine for the last 5 years. 3 pumps on board.
Jeff Rickels
There are too many things that can go wrong when you're on the water, you need to mitigate risk and making the decision to implement a KoolAir pump helps me do just that.
