For one thing, they're using gasoline and diesel at the same purchase
costs....

Yes but that's the least of it in my opinion. It is difficult, if
not impossible to build a reliable, high output, lightweight diesel.
If it were possible lots of other people would have done it by now.
High power to weight ratio is what outboards excel at - diesels, not
so much.

Well, Mercedes is racing a high rpm short stroke diesel and it seems
to work well. I think they even make a car with one - I'm not a
Mercedes guy so what do I know.

Then again, your point is well taken - the whole point of diesels is
lots of power at low rpms.
