Keeping the kill handle pushed in also prevents starting the engine with the fuel off. Below the kill handle is the oil level dipstick. Check it before starting the engine. The oil will look very black and should be between the level lines. If the level lines indicate that the oil is low, add new oil through the chromed cap on top of the engine.
Oil is very difficult to pump out from the dipstick hole.
Aft and below the engine is the gearbox. The lever controls forward, neutral, and reverse. The gears can be operated locally if the cockpit controls fail. The fuel lines run from the port side of the engine to the fuel tank under the port bunk. A separate electrical fuel pump was installed next to the batteries.
