My 1986 390EC has the original Marine Air AC heat pumps that still have the OEM 3 knob controls. The recent heat wave has me wondering if there is a retrofit wifi AC thermostat that could be controlled via smart phone. WIFI is available on the dock if that matters. Anyone find a way to do this?

The 454350HP Crusaders will be coming out for overhaul in Sept. One developed an internal rap on Sunday, most likely a wrist pin or rod bearing.

Install new fuel fill deck fittings on my 1986 390EX. The fill and vent hoses are original and date stamped 1/86. They are marked J1527 fuel and alcohol rated and are not cracked. They are a ***** to remove from the top of the tank with little room to work and will most likely result in much...
