Perkins 6.354 manifold

[Balmoralbob]

Hi, first post, based on Magnetic Island Australia, living aboard our 1947 44' timber cruiser. Am in the middle of rebuilding our mid ' 70s Perkins 6.354, that suffered a hydrauliced engine due to raw water manifold failure. My question is: is it possible to run a standard manifold without water cooling and have water from heat exchanger enter exhaust downstream from manifold to cool the exhaust pipe only. Manifold would be wrapped for protection. Engine room is reasonable size and vented so don't think het build up ould be excessive? My other option is stainless steel custom manifold with engine coolant circulating rather than raw water?
Hope someone here knows the answer to my cooling problems, just really want to avoid costly rubbish manifolds that last maybe 3 to 4 years at $1500 Aust. Dollars

Lancing marine here in the UK have the answer.

I suppose what you suggest is possible, I've seen engine installs without water cooled manifolds. I wouldn't do it, even lagged pipe it'll have a detrimental affect on engine room heat and hence hot air going in will kill HP.

I understand the marine and tractor pistons to be different and that the marine piston is no longer available.

If it was me, I'd either buy a new engine, FPT, Sabre or Cummins.

If on a tighter budget, an ex vehicle Cummins B with E J Bowman manifold and heat exchanger with a Seaboard Marine raw water pump. This allows re-use of transmission (inc its cooler) and adapter plate. Engine has its own oil cooler in the block. Keep the vehicle turbo and rotating electrics.

A friend was in similar situation and we did a lot of considering and diggin into.

At the end of the day the feasible solution was a new manifold from Lansing. In his case also to keep the two engines identical, both on terms of design and working conditions.

In theory, yes. The only issue is the heat in the engine room. I made an elbow for my MD22. The elbow wasnt watercooled till it got to the injection point, a couple of inches further than the VP one. I wrapped it in West Marine figlass tape, quite a bit. It feels warm to the touch when its been running for a bit (2 days across Biscay non stop) but not excessive.
When I first got the boat the engine room fan wasnt working and it was pretty hot in there from the lump itself. I got that working and everything runs considerably cooler. A well lagged manifold and water inj as close as you can get it with a tidy evac fan, why not suck it and see?
