Red Deisel Price

[big_sean]

I am just doing some calculations from some info I have just been given regarding purchasing possibly a new boat but I am looking at the difference in deisel over petrol as most deisels are showing about .75miles per litre and some new engines I am looking at, at cruising speed are showing 1.4miles per litre. Depending on the fuel price difference then the petrol may work out as cheap.

Does anyone care to say what they get the deisel for pm if you dont want to reveal on here


Cheers

Local petrol station sells it for 90p per litre.

Thanks Keith

At that price it is actually only a couple of pence difference to run my boat over a deisel and that is using Richies figures from his advert.

the new engines are better even still so it looks like it will have to be an outboard as its cheaper to buy, cheaper to service and longer waranty

My boat uses approximately 14 lph at a steady cruise at 18knots which if i convert the 18knots into nm it gives me 18nm for £17.92 Using Richies figures posted on his advert he gets 8 knots at 8 lph so to do 18nm it will cost £16.20 the difference is not worth worrying about as the new engines are far better, looks like Jeanneau had done thier sums and that's why most of their new boats up to 25' are all outboard engines. It also made me wonder with so many commercials usingb the cheetar catermarans with outboards on as to how much was in it as they would surely find the cheapest.

Anyone care to add to this with other figures ?

Cheers

I'm sure the diesel is a lot dearer at the RQ marina.

That would make the figures look even better for the petrol boats lol lol

Well here are the boats and figures

Diesel Boat
50k to purchase
Top speed 22/23 knots
Cruising speed 17knots @ 17lph
Price for 20nm = £18
Engine warranty 2 years
Hull warranty 2 years
Everything else 1 year
Service costs for 5 years estimated at £1000 which includes 3 4 and 5th year doing it yourself.


Petrol boat
44k to purchase
Top speed 36 knots
Cruising speed 22 knots @ 15lph
Price for 20nm = £17.45
Engine warranty 5 years
Hull warranty 5 years
Everything else 2 years
Service costs for 5 years including checks done by self-£350

Both boats are angling boats and withing 10cm of each other in hull dimensions.

but back on topic ......

Its a difficult one Sean, kind of balanced now since diesel is closer in price.

I always added the longevity and simplicity factor of an inboard deisel on a straight shaft. Diesels go on forever many more years than petrol ....
But on the other hand, if eventually it does get old and slow and you want to re-engine .. well its a b1tch if its an inboard compared to a simple outboard change.

seems like 6 and two 3's ..... currently I'm more than pleased with my 13 year old diesel, however if I were now to look at a totally new set-up I think I might go for an up to date outboard ............. well ... maybe

by the way I get about 0.95miles per litre at 18-20kts, used to get 1.2 a few years ago but there may be other factors, like its time for paint job, time for a strip down of all the rubbish I keep taking on board etc.

probs no help to you but anyway .............. good luck

Hi Norman

That is actually staggering as the most planning hull out of them all is Slinky and that makes the fuel look a tad better at your quoted 1.2 per miles per litre, So a big thanks for the info. I think a few years back it would of been a diesel well before a petrol boat but nowadays its beccoming very close, i have seen commercial outboards with thousands of hours on so the longevity is also getting sorted. These fourstrokes/ and new gen two strokes are so reliable and seem to be going on forever.

Like you say the bolt on bolt off appeal of the engine is a big pluss as well as if you get an outboard in ten years you can upgrade so easy and because outboards are in such short supply the second hand market is fantastic so it would be so easy to move to a new engine

keep the figures comming lads as it does paint a good picture of what costs

When i had the M/F 635 with the 85hp Nanni engine, the raw water pump went when the boat was 10 years old, the new one was £650, plus an adaptor plate £70 due to the old pump being discontinued, quite a pull out for something you could put in the palm of your hand..

Fuel consumption was around 1ltr/mile at 14 knotts with a clean bum.....which i was happy with, especially working on a building site..if you get my drift....

For me though, i would go outboard, easier to maintain, no shaft or rudder seals, faster and the water pump isnt as expensive to replace...

Can't fault any of that Chris ... the view (10 or so years ago) of a diesel was that it was frugal on fuel, also it was using cheaper fuel as well and if anything got wet it didn't stop ....... but seems new petrol outboards probably now tick all those boxes.... with their own added extras ... power/weight ratio and changeability (upgradeability).

One thing i would say though, is the diesel engined boats seem to be more stable at drift, and plough through seas better than outboard boats, the lump in the middle of the boat makes a big difference to the sea keeping.....plenty pro's and cons for both i reckon......

I think if a boat is designed for an outboard then this will change, my boat is great and drifts perfectly, my mates who's boat was actually designed for an inboard but his is the outboard vesion drifts ok but no where as straight as mine, and at sea it does not perform as well as mine.
