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.
Report Abuse. A. Inboard, the engine is inside the hull of the boat. B. Outboard, the engine, (along with the gearbox and propeller), are out side the hull and hang off the transom, or rear vertical end of the boat as one unit. C. Stearn drive i/o. just now. Report Abuse. There is no difference between an inboard/outboard and a stern drive. The inboard part means the engine is inside the boat. The outboard part means the outdrive including the transmission is outside the boat as it is on an outboard motor.
