what about the fuel tanks ? ( sorry,can't wait any longer for someone to ask)... now's the time to change em out....?

Gas versus Diesel. (At least here in Europe)

From time to time this question comes up. Gas or Diesel. I have made a calculation for the "problem". I had a boat with around 700 Hp totally, twin gas engines. To drive this boat WOT did cost me the merely lump of 3900 Norwegian Kroner pro hour, or around $670 US Dollar. Each hour!!!
On one hour the boat travelled 26 Natical Miles. Which will give a price of $ 25,76 USDollar.....or about 40 times more than my aircraft. The price of Gas here in Europe is today 14,20 NKR (krone), or $ 2,53 USDollar / Liter, or $ 9,60 USDollar / Gallon. The diesel costs around the half price of gas, or 7,88 NOK. On my "new" diesels the fuel consumption will be around 12 Gallon / hour WOT. Or 45 litre. The speed?? Almost the same. Then it´s simple to figure out: If you use your boats for 100 hours a year, there will be a lot of dollars or krones to be saved. Or...???

I am sure I have missed this! but why would you convert to lesser power? I can understand doing it with diesel but not for gas to gas

PK 12 gal per hour per engine correct ?

Paul: The Navistar Diesels works OK on 45 Litre / 12 Gallon. But even if you put on a 5 Gallon the result is pro diesel.... And offcourse the price for a gallon.

Not sure what your saying , But I was asking 12 gal per hour was per engine at WOT

PK - our government has it so screwed up here that our diesel costs MORe than gasoline here. But I'll never have gasser inboards ... but not fuel savings on price/gallon - but much better mileage ... and more reliable ... and safer.

Gettaway - engines look nice - When I saw you post, I assumed you were going with those diesels you found last fall - no deal? The L-6 gassers will be ok, but not very fast. Why not just rebuild you V-8's?

Paul: I mean the WOT will make the engines go on 12 Gal. @ 3400Rpm. I am not sure how high Rpm I can take out, but there is a tag on the engine that says 3400. But even if you put on 5 Gal. extras because the injectors are a bit worn out, the diesel pump is a bit "low" on the injection point, even then you will have a positive result. Especially here in Norway. By the way: we celebrated the Norwegian National Day today, May the 17th. In a cold and rainy day. But there was a celebration...and tomorrow I´ll be back in the engine room in my Trojan.

PK I think you missing the point 12 Gal per engine ( 24 gal per hour for the boat ) at WOT , thats sounds about right .

Not sure what the 5 gal thing you talking about .

Norwegian National Day!?!?

I'll toss down a linje akvavit for you tonight (I wish!)

Cheers

Gotta ask.....with that much less power what do you gain? You will have to run those 6's hard to get the same performance, if you even can???................John

Paul: As soon I´ve got her splahed I will give you the right numbers. Or at least as right as possible. I will use a "flowmeter" on the fuelline, and multiply it with two (one for each engine).

Ross: Thanks. I will put out some pictures from the celebration on "The Norwegian Trojan"-string. But Ross; I had myself three shots Aquavits. That stuff must be good for a "Ancor shot"...? The one you take when finished the lowering of the ancor in the evening.

PK I don't need thouse number was just wondering if your figures where for 1 engine , as I have 300hp diesels I know the fuel burn is well over 12 GPH per engine at WOT

Speed is not what he is looking for
