Perkins 6354 - Fuel Consumption?

[l'escargot]

Twin Perkins 6354 in a semi displacement 39ft boat with a cruising speed of around 12 knots. What sort of fuel consumption per engine per hour?

 

[Jim@sea]

All these Perkins engines were used in Massy Ferguson Tractors and if I was trying to find out gallons per hour and it wasent readily available I would try and look up Tractor informatopn. Certainly buy any engine spares from a Tractor dealer

We used to have a semi-displacement Broom Ocean 37 with these engines and used to cruise at 10 knots when we used 4.5 gallons per hour for both engines if my memory serves.

Are they turbo or NA?

If turbo, then at 1800 revs you'll burn about 2.5 gallons an hour each.

No idea about NA.

no idea what gph (have a pair of 175shp)in the moonraker.unless run flat out i find very good on fuel.
i just fill up when the tank needs it.!

Ours were the turbo version and the 4.5 gph we recorded would have included some displacement speed cruising in rivers at each end of a sea passage so 5 gph for the pair at 12 knots sounds about right.

I am sure epervier has a pair of these in his Weymouth 32.. but I think he's out enjoying the water at the moment..

BTW, if you want a spare I spotted this a couple of days ago..

He has a pair of the HT versions, lying on their side, I have the upright T6.

Ah...should have said that ours were the HT versions. Not sure if there is a difference in file consumption between the two versions??

Turbo and I am told rated a 220hp each which seems higher than other engines quoted.

You need to provide a heap more infomation.

Max rating of T6.354 was 175 (150) Hp.

T6.354.4 went to higher power ratings 200 (185Hp) being one. However these were significantly different engines from those quoted. Range 4's had watercooled Holset H1 turbochargers and the dreaded 'Manicooler' set up.

Getting it in bits and pieces does T6354M add anything?

Absolutely ziltch!

Engine serial # on machined block face at base of fuel pump.

Some simple ways to spot a Dot 4 are;

Alloy not tin rocker cover.
Viscious not bonded crank damper
Water cooled Holset H1 turbo, not dry 3LD
Socking big combined manifold heat exchanger 'Manicooler' instead of simple wet manifold.

Oh and fewer oil leaks.

The Dot4 esn# should start TU,V,W,X etc in example format TU6.354.4UXXXX

Well they certainly looked clean without oil leaks. Should get a closer look at them and some more info this week. Thanks.

Alloy not tin rocker cover.

I get excited about those.

the t =turbo
6=6cyl
354=cubic inc
m=marine i.e not a automotive converion.

hmm..and mine dont have a oil leak either!!

 

[epervier]

At cruise 1600/1800 rpm 6 gallons per hour for both donks, as always depends on how lumpy it is out there, I can give a more accurate guesstimate later in the week when I bunker again, I've logged my running times yesterday and today so I'll be able to give a closer number, if you're interested.

Begs the question, why was rear main oil seal arrangement redesigned on the Dot4. 'To eliminate rear main oil seal leaks at high installation angles found in marine applications'. Their words not mine...........

That's not a common fault on mine....only the port one does it.
