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?

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

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

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