Don't confuse Saab with Sabb. The Sabb diesel engine is one of the most simple and dependable diesel ever built. They were used as lifeboat engines as they could be started on the davits and let run for a long time before ever getting dropped in the water. They usually have either hand start or electric and do not suffer the same reversing problems as most feathering prop systems. They usually don't have much power and weigh a lot so can make a great contribution to ballast. If you like the sound of the African Queen then you will like the sound of the Sabb.
