Im no expert, but is the 3.7 from the same family as the 4 litre, wet linered aluminum blocked motor (models 470 & 488) that had an alternator built into the front pulley, a bit like an outboard? they were designed from the ground up for marine use, but were a bit of a disaster I think, especially the alternator, that cost a grand to replace (regularly)
Might be wrong though.
