Hey all,

This is more of a boating question but : I'm looking for a car engine which is reliable and mainly mechanical for a boat transplant.

The boat currently has an old ford 2.5D engine which not only drinks fuel, but from the information I've found produces a pathetic 76hp at its peak output.

We're looking for an engine suitable for marinisation and really I'm after any suggestions here -

The only current candidate is the XUDT peugeot lump, if anyone has any other suggestions it would be much appreciated :)
 
XUD is really really great.

However volkswagen 1Z or AHU is just as reliable and marginally better on juice in my experience.

This is in cars however. In boats maybe XUD might be a little simpler as it doesn't have an ECU like the vw lump?

Kind Regards

Alec
 
The Rover L series is a very good mechanically injected diesel engine. It's predecessor, the "Perkins Prima", was quite popular for marine use though I don't know if the L series has been used to the same extent.

Note that a turbo-diesel will have rather different torque characteristics to the old normally aspirated 2.5, so check that the gearing and/or propeller pitch will be suitable.

What boat is it that needed a Transit engine ?
If you are looking for good MPG then the smaller the better, You'd be surprised at how small an engine you can get away with.
For availability, cheapness & long life you can't fault the XUD engine though & I would go normally aspirated as well as there's no need for a turbo. Simple wins on boats every time.
 
The only other thing I can think of is the Isuzu 1.7TD, but the XUD is a better diesel lump anyway.

Anything without an ecu is a lot better. The idea with the XUD/XUDT lump was that all it needs is power to its stop solenoid and then it'll run.

I'm considering that we can take the glow plug relay setup from the donor car too, essentially taking out the guess work required. (The ford doesn't have glow plugs and every other engine we've ever had in the few boats has had them. The BMC 1500 certainly demanded massive glow time for it to be interested in starting.

A previous boat we had, was fitted with a perkins 4108 engine. This lump was horribly noisy and it had a very interesting way of starting :

(Watch over at the left hand side of the engine - single injector spray over a hot glow plug!)

The only thing that concerns we with the straight diesel is whether it will be more lacking than the 2.5 that comes out. I know the 1.9 makes 70 hp which is probably in reality, more than enough for the boat but I think we need to speak to some specialists in regards to marrying it up to the Z Drive anyway.

Thanks for your replies and help so far though guys!

I'm trying to find out the model for you, depends on when I get a reply from my uncle. I personally would rather fit it with a 1500 BMC, but my uncle isn't keen on them compared to the more modern diesel. (Probably the fact that you have to crank them over for half a minute to get them to start!) Disturbingly I like the sound of them though :eek: :(

Other than price saving, what's the difference between fitting a car engine and marine engine?

Just ebayed Marine Diesel engine, first hit was a 43k Royal Navy unit.

Buy that :p

That engine would probably sink his boat mate ;) With some engines there is no difference, the BMC 1500 diesel engine is one that was fitted to many vehicles and early taxi's. That engine simply has a few parts such as cooling system changed and its good to go in a boat. I believe they were also in Morris Marina's.

You can buy marine only lumps but a lot of people have a marinised xxx engine in a pleasure boat.
 
In a boat, would be it be safer to have a non-turbo version? Just conscious that a turbo failure might be a little more unpleasant when instead of having pull onto the hard shoulder, that you might need to row a 23' boat.

The sea is one big hard shoulder, just a shame that the RAC won't come out to you ;) You have a good point, from further research the turbos get incredibly hot when confined to an engine box.

IIRC that's the same engine as the early Vauxhall Combi van and they are capable of 1/4 million miles no issues

Indeed, they were also in the cav td and my friends was on 300k when he sold it :eek:
 
Indeed, both of my 306 engines had Lucas pumps (both xudt).

What sort of age VW engine are we talking for one that doesn't rely on an ecu?
