I think i would prefer something a bit more agricultural nice though these common rail diesels are i really dont like all the electronics in a marine enviroment. would a cummins 5.9 be too heavy? probably powerful enough though.

I couldn't agree with you more re electrionics, which is why I'm a CAT man, but they is big and they is heavy, The same can be said for that Hull. it's built very strongly and meant for twin outboards. The electronics is getting more and more difficult to avoid nowadays however.

To get good performance from an inbosrd on this boat it would be nice to keep the power to weight ratio similar or better than the original outbords. Dontt forget the diesel going to beed some form of drive system which will also add weight.. 325 kg gives 265 hp and 550nm at 2000rpm

The power to weight from these little devils is great and the engine is so well sussed for access to mainenance parts, that I'd certainly give one a go for leisure ppurposes before I bought a Yanmar.i think its the 6lb/260 which is very close in specs.

Now enough about Fantasy Boats I can't afford can you tell me where did you get the plates from to shove a Trooper engine into your Landie 110

Hi Stu

I made the adaptor plate and engine mountings for mine as i had access to a big lathe and plasma cutter, so it was fabricated and machined.
however they are available off the shelf from

cummins 6bt 400Kgs 300HP
I bet with all that lovely cold seawater in the intercooler you could get another 100HP still a bit on the lumpy side though.
BTW my mates got a 6bt in his landrover

I would also question whether this is actually an Atlantic 21 hull or not. Why has it got an inboard engine compartment with stringers that look exactly like a P22? Did Atlantic 21s come with a big planning wedge at the stern and why has it got a Halmatic P22 console on it. Something not quite right here but for the price could be an interesting project, Viv's Christmas present perhaps

The console is an Atlantic 21 console. The big hole in the deck looks like an inboard should be there but thats where the RNLI fitted the fuel tanks, the filler was under the rear seats. Not sure why it has a tank under the helm as well?
The tubes look to be ex RNLI, ie the big orange patches where the operational number and RNLI would have been.

Either way it a nice boat but I can only just fit an SR4 on my drive!

Do you not think that the hull was built as a Pac22 but instead used with twin Outboards instead. Looks as though no leg has ever been fitted, the engine bay looks too clean too, with no obvious fixing holes etc.

Too big a project for me, but am considering starting something soon

going by the pics ,,pity there is none of underside of the hull,,i recon it is ex rnli ,, as chewy said , the console and some of the fittings on the tubes look rnli ,though i cannot see where the rubber catch hook was stuck on for the trailer , and its been converted to a work boat or used for diving either commercialy or by a diving club at some time ,,seems to be a lot of checker plate added ,,possible they kept diving cylinders in the old tank space ,and they just put a new fuel tank under the console .,,with regards to the planning edge on the stern ,it was there to keep the boat upright when beaching and also gave it a bit less draught in shallow water ,,reason why they kept it on the 75 and the 85 s,

Even the seller isn't sure what it is:

Dear pete9501, not 100%but if it is not it is very simular - chriswilks0

Did the Atlantic 21s have a deep V hull or a planning wedge under the transom?

Looks slightly different?

The hulls changed all the time on the RNLI boats. The first and last hulls will have quite a few modifications to them.
The very first ones were wood!
