I love the idea, but why oh why did he not put the factory dash and throttle housing back on?
That throttle mount looks hideous, only to be outdone by where the center seat should go.
Also quite interesting is that non of the exhaust is water jacketed. Doubt it is water injected either.

I have thought it would be awesome to do a cummins swap but that would be much easier since they are already installed in marine applications so no re-inventing the wheel.

damn! sounds like it was done right. although a lot of computer controlled stuff.... agree cummins would've been a better fit

I'd be more concerned about the lack of a water cooled turbos and piping........ especially with twins. Wrapping them helps, but that's kind of a duck tape solution to that heat issue.....

Are those not oil cooled turbos? Maybe I don’t know enough about diesels, does this motor use a cooled headifold rather than straight manifold? Heat management is probably a concern as with any swap but I don’t see any big indication from the pics that it would be a huge issue.

It has a water to air IC, which is way more efficient than air to air IC.

Like eric said, no water cooled manifolds or turbo's means you have piping that will be running 600-1k degree's inside of your boat with only a bit of insulation tape covering it.
Recipe for disaster along with being illegal if I remember correctly.

Cowwboy pretty much covered it....... but ya, the exhaust manifolds and turbine housing are not water cooled, and they should be. The turbine housing gets red hot under load, and every marinized diesel I have ever seen, has an integrated cooling jacket on the manifolds and turbine housing.

Yes, the center bearings are oil cooled/lubricated, but that doesn't relate to the issue I am talking about. Same with the charge cooler..... neither of those are going to help the heat issue outside of the engine..... same reason the exhaust manifolds are cooled on a normal N/A engine, only in a turbo engine, the turbine housing needs to also be cooled, because they can't introduce water into the exhaust stream pre-turbo.
