Quote from Porrohman
How much commonality is there between the RR Tyne engine and propeller on the Guppy and those on the Belfast? The both have the same power output but have a different model designation. Is it just the mounting arrangements that are different or are there other differences?
As far as I can recall, the auxiliaries on one are electrically driven and hydraulically driven on t'other though I am damned if I can remember which is which, they are not interchangeable. I am sure one of our more erudite Tyne artisans will clarify in much greater detail soon,
I hope.
Hope it helps
Be lucky
