Army Surplus Perkins 4108 Link

[Spirit of Glenans]

Didn't the early diesel Ford Transits (the ones with the extended nose) have Perkins 4108s?
Volvo use Perkins engines as bases for some of their products, so this might be of interest to the owners of clapped out examples of such engines. It's almost the right colour

Also don't forget that the timing cover will have no mounting for a raw water pump. Whilst all these things mentioned are not show stoppers I don't think the unit is worth the asking price given no history and the fact that a lot of work will be required to fit it to a yacht.

Indeed, and no requirement for a water cooled manifold or a wet exhaust. There's many a fishing boat has a dry exhaust either straight through the side or vertically to above the wheelhouse, with insulation or a grille to prevent burns.

True, although it's a rare sailing yacht that can sensibly use a dry exhaust, it would almost have to be designed in from the start. Indeed my fantasy low-tech long-range cruising design had exactly this feature, passing up through the back of the oilskin locker (for drying) and then up the inside of a sturdy boom gallows to above head height. But since coming up with that I have doubts about its practicality - even with a big silencer it would probably be a bit noisy and smelly in the cockpit, so the boat might be better off with conventional water cooled exhaust after all.

It shouldn't be too difficult to either source or have fabricated a suitable water-injection bend to add to the engine in this thread, for wet exhaust. I don't think a watercooled manifold is essential, it's not unusual to see engines with a short length of dry pipe before the water comes in, usually lagged with fibreglass tape.

From what I remember from my friend who used one as the basis for his engine replacement project, the outer castings would not take the marrinisation kit and the mounting feet locations were not even close.

He intended to simply swap the manifolds and pumps over to quickly replace an engine with a poorly crank..... he ended up spending a lot more than anticipated and ended up with a Frankenmotor.......

The only Perkins based VPs I know of are the MD22 and the turbo versions and the MD20X0 series. Happy to be corrected.

I was sorting some stuff on a Swan last year and the 4-108 had been replaced with one of these. The original had seized from water coming up the exhaust (second time) and my brief was to stop this happening again.
All the marine bits had swopped over from the original, so it can be done. The owner said it come out of a tank and it was the same colour as the photos. Some where I have the phone number of the bloke who did the swop, if anybody is interested.

Not quite. Never heard of a turbo version of 20X0 series - all 4 versions were naturally aspirated and based on Japanese made Perkins engines (also sold as Perkins Perama). Latest D1& 2 series engines are also based on newer Perkins base engines made in either Japan or Peterborough.

The Perkins 4 108 predates all of these and was never used by Volvo but was marinised by Perkins, as well as being is being used in a wide variety of industrial, commercial vehicle and agricultural applications.

I was referring to the MD22 series only. I know the 20X0 series werent turbo

Sounds like its a no go for use in a yacht and not particularly cheap unfortunately.

Very true, and the fact that it is ex-military and requires an export licence means you'd never be able to sail abroad without getting an export licence first (or knowingly face crippling fines)

Que? In the case above, who on earth is going to look into where your replacement engine block came from? Registration and insurance, maybe. But looking for engine numbers and tracing their history?
As for the 'no go' for a yacht, worked fine for the one I looked at.

It would be a risk especially unless you have the skills to strip it down and inspect.

Unless you have an old donor engine the marinisation parts add significantly to the cost and that's before any extra costs which may be incurred overhauling the engine.

Probably best regarded as a replacement for an existing clapped out 4108 with useable marinisation parts.

I happen to have a clapped out motor with the marinisation parts if anyone wants to use one?
