It’s great to have push buttons and gauges out in the cockpit for the Volvo Penta D2-75 diesel engine, but what happens if the electronics have a day off? Here is a demonstration of how to start the engine manually. Hopefully it’s not an emergency when you need to do this, but it’ll probably feel like one if the engine didn’t start when you wanted it to. We keep the short wire we made up for jumping the relay socket in the second drawer. Two of them actually. You need this to be handy. Keep in mind that a paper clip will do the job if needed.
