Mix n' Max no go!
Mike,Mixing and matching parts from one manufacturer to another is asking for trouble in my opinion.Manufacturer's build their equipment and test it extensively to insure performance. At best, you are rolling the dice. Even if you got a cracker jack expert, you might just get an answer after the fact that they are incompatible.On a boat, a relatively minor efficiency loss can have a performance impact not to mention the ripple effect of battery capacity, etc, etc.Stick with the choices provided by the manufacturer. If that doesn't suit your application then contact A/B for a practical solution. If they review the specs of the evaporator you want to buy and approve it, then go for it. If not though, I would definitely recommend staying away from it.Good luck,Mike D
