Lister petter fuel consumption canal star or LPSW2

[Peugeot 106]

Does anyone know why canal star 18 is 1.3 litres/hour and LPSW2 is 2.1 litres/hour they seem to be same engine?

[Grace and Favour]

Are they quoting the same rev's - and are the figures under load or in neutral

 

What size of boat, or are they control figures?

[Peugeot 106]

Different data sheets which I don't quite understand. I've just bought LPWS2 so worried I should have got canal star as consumption seems to be a lot less but engine seems the same? Boat is 25 feet narrowboat which had 10.8 bop engine which was too small

If the engine specs are the same then you may find that the differing fuel consumption figures are under different condition. Take the average.

 

I would doubt however that both or either tests were on a 25ft boat so probably not relevant to you anyway.

I'm suprised you find 10.8 horses to little for a 25ft canal boat.

 

Have you looked at prop size/type?

 

Ahh... To late, you bought the motor.

I have a LPWS3 and I average a litre/hour on the canals and this only doubles when on the river running flat out. So I would not worry too much.

Are the data sheets both when it is at max revs? If so, its rare that you will be doing that.

That fuel consumption seems to be par for the course. I reckon the OP is worried unnecessarily before he has even done some boating with the engine. I'm sure he will be pleasantly surprised when he gets some first hand data.

Thanks for the reassurance. Taslim the surveyor tried the boat and said the engine is a bit small especially for rivers/tidal . The prop is correctly sized I checked with a prop refurbished. The previous owner said he needed tow on Ribble link we are in Lancaster and also struggled Thames. I have done a lot of sailing on yachts and fitted engines myself but am new to narrow boats though appreciate low power is the norm. I have motored across Irish Sea many times with 7 hp vire so know what is involved. I talked to many people and the consensus was that 15-20 hp would be better

Rang Lister Petter today - Essentially Canal Star and LPWS are same engine so that solves that!! Thanks for help

We've had Hekla since January and have clocked up 396 hours using 346 litres, so that works out at 0.88 l/hr, with a mix of moored, canal, and river - including the Trent in flood against the flow.

I have just solved this mystery - the engine couldn't have made more than 5.4 HP. One of the big ends has gone, probably due to a bent conrod as the piston describes an interesting dance at the ends of the stroke
