Sorry but I don't agree with you on this. A diesel is not a diesel. You can't say gas engine is just a gas engine when talking about planes, do you??
I agree that its easier to get parts for land based engines, but you don't have a normal land base diesel on a boat (even Volvo has "marinized" their engine). Some spares might go, but most won't.
I don't know about Westerbeke (Isuzu) engines as we don't have them, but then again I bet you don't have Volkswagen marine and we do. that is why I kept my opinion limited to what I know, Yanmar and Volvo.
We also have NANI, do you have that there??
Now for me, I rather have a marine diesel, designed from scratch for a boat, than a land modified to go on a boat. Where the differences inside are, I have no idea, but I have had my engine all covered with salt water and still no rust. Do that on a regular diesel and see. Besides I have a sail drive, and that changes everything, also. Sorry for not agreeing. Ok?
By the way, what is a city slicker??? I am sure I am not that!! I do not burn money
As for the Yanmar curves, as requested by Jones, Hope they are visible.
From my engine catalog!
