Sorry if this is a dumb question but I'm a new owner. I tried to remove the cowling from Mercury 115 4 Stroke CT #2B187251 to check the oil etc by pulling out the lever on the back of the engine but the cowl wouldn't release. I bought this boat used from a dealer with only 30 hrs on the engine and it doesn't have a manual.. How do you remove a Mercury engine cover? What is a cowl on a boat motor? A cowling is the removable covering of a vehicle's engine, most often found on automobiles, motorcycles, airplanes, and on outboard boat motors. On airplanes, cowlings are used to reduce drag and to cool the engine. On boats, cowlings are a cover for an outboard motor.
