I'm not sure how this works out in practice.

I have also been under the same impression as some others in this thread,
that diesels are so much more expensive than gas engines that unless you're
using the boat commercially - heavy, regular use, day after day - that it
will be many, many years until the fuel savings catch up with your capital

While it's true that it will take a lot of use for the more expensive
diesels to pay off monetarily despite the higher resale value, you also
have to count in the greater range as another advantage. For people who
boat close to gas stations, that's not important. But if you want to go
offshore or have good cruising range, diesels can get you out further
and back then gas engines.
