My son in law has just got a 25' Bertram with a stuffed Volvo diesel in it, he is wondering whether to replace/rebuild it, toss it out and put a pod and outboards on it, and even though it is a tiny 4 cyl diesel motor, the engine box is gigantic, often thought about some sort of flat diesel, the Subaru engine although a flat 4, is still reasonably high from bottom of sump to top of motor, mind you, nothing like a "normal" motor, in something like the Berty, the really deep V makes for a lot of room under the floor, that a flat something would fit into very nicely.
