Is a marine diesel feasible for a small pickup truck?
I don’t see an easy way of implementing marine diesel into small pickup truck. It just something that doesn’t belong there. There are numerous problems that will pop out for you to improvise toward the final goal – very fuel efficient p/u. Cooling, power transmission, differentials… You should know that marine diesel engine will burn much more fuel than if you use some other engine and improvise mounts and few other things. The resistance toward moving of a vehicle compared to a boat is a lot bigger and small marine wouldn’t do the job. Bigger might but then you loose your starting idea for all this. Why not just find an old VW w/ diesel engine 1.6l and fit it in the truck. There is a movie in some European country as I can recall where dude is trying to make a PLANE powered with this engine. Of course… he failed… but then again… it’s just a movie…
