That was actually from the booth for
Hyundai-Seasall, which is a company that makes diesel engines. I meant to get back to them and ask them more about it, but I forgot to do that before I left. It looks like they rigged up a VLX with a V6 diesel. It would be really cool to see what the performance on the water is. It still seems surprising that no boat company has done this yet. I'm probably missing something, but it seems like a good idea.
