Been in a trawler fishing boat with a Rootes-Lister TS3 engine

I was aknowledged about the existence of the Rootes TS3 engine with its distinctive opposed-piston, horizontal cylinders layout, just never had a chance to see one still operational. Though some old Commer trucks could still be found in Uruguay about 15 years ago, most of the ones originally fitted with a TS3 had received an engine swap and were using Mercedes-Benz OM352 engines. But at the moment it's the least important, what really matters is how efficient and comparatively compact this engine is. Quite amazing that 2-stroke Diesel became unpopular in trucks and buses while they're still successful for marine applications. Biodiesel and vegetable-based lubricant oils could overcome the high hydrocarbon emissions issue.
