Do motor boats use this Heat Exchange method?

It just seems like $500 dollars is expensive..

Any thoughts?

Yes, I do. It's only half a boat buck.

If that seems expensive, then you don't appreciate the realities of
trying to manufacture and market specialized, low volume equipment. I
doubt that anyone is getting rich selling this stuff. With all due
respect, if $500 seems expensive to you, then you should reconsider
getting a mid size cruising sail boat. You want to be in a position
where you own the boat and not the other way around. Seriously,
$500 is the tip of the iceberg.
