I have a 1996 Nissan Maxima. It was about 95 degrees today (measured with my own thermometer not what the weather report says), and my air conditioner outlet temperature was reading about 50 degrees. that would be temperature differential of about 45 degrees. I had the fan on second lowest out of 4 settings and on recirculation.
Outboard Engines. 1  An outboard is a portable, self-contained package of an engine, gear case, and propeller that is attached to the transom of a boat. 2  A growing number of outboard engines are of four-stroke design, but many are still conventional two-stroke engines that burn oil as a lubricant along with the fuel.
They are inboard engines placed at the stern of a craft, connected to an outboard drive system. They are also called inboard/outboard motors or simply I/O.. Outboard boat engines are a single unit of both motor and drive system mounted on the stern or transom of a vessel.Outboard motors steer by pivoting the entire engine/drive unit.hey are also called inboard/outboard motors or simply I/O..
