NEV'S 32 LITRE V12 ENGINE

[Bigbjorn]

My old mate, Neville, has acquired a couple of WW2 marine engines, a handed pair, left and right rotation. They are Hall Scott Defender V12's, 32 litres.

He has got the right hander running. Starts easily, runs well, and doesn't it bellow through those straight pipes. Takes 2 litres of gasoline to fill the three huge bronze carburettors. He had to get the two fuel pumps on the camshaft ends plumbed in and working. A normal automotive electric fuel pump was OK for priming the bowls but can't keep up.

Magnificent engines there Brian. What did they come out of, a landing craft or something like that. I have been told that some of the Yank WW2 landing craft LST's or similar had engines that were identical but one was reversed (I.E. bell housing fitted to front of engine) for the LH motor. You cant beat big cubes!:)

He has the pair. The left hand rotation one actually turns in the opposite direction, not reversed to drive from the opposite end.

They were used in a wide variety of small craft in WW2. Try google.

The PT boats used a different engine, Packard M2500's. 2500 cubic inches or 40 litres. Developed from the A2500 aero engine of the 1920's. Again, use google.

Those engines were used on RAN Fairmile class patrol boats (among others) during WWII. My late father was a stoker on those boats (mainly ML-816) and knew them very well.
See Fairmile B motor launch - Wikipedia, the free encyclopedia

These two books give an excellent description of the RAN boats:

Brian
Is there a chance of hearing these works of art on a Youtube clip mate? What a sound they must make.

I've seen a Fairmile in Auckland, it was in private hands. I can ask someone to find it, I used to volunteer with the Coastguard doing SAR so still have a few contacts there. It didn't look like it would be very comfortable in rough seas though.

I've started a thread on the British Military Powerboat forum about them here. (http://www.bmpt.co.uk/forum_posts.asp?TID=813) It will be interesting if they can spread any more light on what they are for.

Now, that's what I call an engine :cool:. Your mate Neville must live rather isolated or being on very good terms with his neighbours as the test run obviously could not have been done in stealth.

He lives out on the black soil plains from Dalby. No neighbour close enough to be disturbed. They all come along for a look and listen anyway.

What does he plan to use it for? Or is it just as a curiosity?

One suggestion is to low mount it behind the cab of a small forward control truck. 3-4 tonner.

Actually, something like a Toyota Dyna, Isuzu NPR, or even a Bedford KCC if one could still be found.

The engine cover could be made to look like a large case or package.

It could only be a show vehicle as the Street Rod Federation Qld. branch has a self imposed limit of 500 cubic inches. 1950 is a tad in excess of that.

Other WW2 Vessels that used these motors were the RAAF Air and sea Rescue 63ft Patrol boats 1944-1985

Brian, saw these sold a year or two ago. Running motor made about $5600. Not sure on the one for spares. Hate to have to set up crank clearance.

When I was in High School one of the other boy's family had one of these. About the only thing I remember about it was that they had it shipped from Melbourne to Sydney by road to save fuel......

Would be just awesome in a period 'monster' type old car, depending on the physical size of course, maybe something built around an old Bentley chassis.
