Re: Turbo diesels

Hey,

If the turbocharger locks up so that the shaft won't turn, no, the engine won't run. The turbocharger is driven by exhaust gas, if the exhaust can't get past the turbine vanes then the exhaust can't get out. If the exhaust can't get out, the engine can't run (no gas out = no air in).

There are situations where the turbocharger won't work (generate pressure) but the engine will still run - burned turbine or compressor, etc, the engine will still run but will make much less power.

Personally I have no experience with turbocharged marine diesels so I can't offer any advice on spare parts.

Given how expensive they are is it worth it to carry a spare(we carry a spare alternator)? If the engine can run without a turbo what does that do to the engine?

Thanks.
