Has either of your units, the water pump or duct work been modified? I find it hard to imagine that the boat manufacturer wouldn't install adequate AC for 90 degree temperatures.
You've convinced me to run Barnacle Buster through my AC water lines. I'm willing to bet they've *never* been cleaned. Mine are marginal on very hot days. I might get a nice bump in output.
