We're islanders too, very familiar with this. We use a wet / dry vac to pull as much of the residual water out of the pump section and compressed air on the pressure side. Switch the hot / cold temp control a few times while blowing it out to get both the hot and cold sides of the water solenoid valve. Final step is pouring some RV anti freeze down the hoses (flip the temp control a couple more times) and then roughly a half gallon into the tub to dilute any remaining water in the pump. Only takes 5 to 10 minutes. (Not including horsing the shop vac and compressor around...)
Wait, why are we talking about this??? It's still summa!
