I'll be back soon ...

I note in one of the docs that the engines were supplied with the oi filter inverted to fit in the packing crates. Perhaps something that was to widely explained as both of these have the oil filter still inverted. This means whenever the engine stops there is a risk the filter empties into the sump, meaning that it has to refill before the bearing receive their oil. Less of an issue with anti drainback valves in the filter, but I think I will be putting them the way up they should be !

Apparently an engineer is looking at the pump tomorrow, and I hope it is simply the impeller core disconnected from the body of the impeller.

When the dust has settled on the sale etc think about driving the pumps with a very short tooth belt drive to give you the freedom to get the pump in a maintainable position.

Definitely !

Also reading various documents on these older Ford diesels there are comments that the double drive did place excess load and consequent wear upon the gears driving the injection pump, so yet further reason for some re-engineering. There is reasonable space around these engines so re-positioning the pumps may be a good idea for more than one reason. Can't see this being such a difficult task once the pulley conundrum is sorted. I also intend to fit water flow switches as further protection as I am now paranoid about engine water flow.

Very good idea as I think on none marine version used the rear of the fuel pump for a tacho drive, much less demanding than a raw water pump!

So...are you accepting the boat ‘as is’ since you now plan to modify the engines?

Yes, I was wondering the same thing. I was mildly interested in the boat when it went on sale, but those engines put me off. Rather than modify engines that are heading towards 50 years old, I thought about a re-engining project with a pair of Yanmars. However, I couldn't make the sums work out at the price they were asking.
Maybe you've got the price down to a point where new engines might make sense? My fear would be that those old Fords will always be unreliable. Anyway, best of luck, whichever way you play it.
 
I remain interested, but the engines have been neglected and if these were found to have internal wear or defects beyond a decent service the costs to overhaul would be quite significant, and to replace would exceed the value of the boat. The likelihood of finding a pair of secondhand engines that would suit the boat is very remote, so the only viable replacement option would be new. I was quoted ~ £16.5 k each side, plus a further £8 - 10k to install.

It became apparent last week at sea trial that one engine that would not start at my inspection visits, had apparently been fixed, only to discover the sea water pump did not work when started for the sea trial, curtailing that (who fixes an engine and does not check for water flow when starting the engine up !). Clearly no service of these awkward to remove pumps has occurred in recent times. I also read up this method of pump drive via the injection pump was found to cause excessive wear of the injection pump drive gears, after all the take off used was originally intended to be a tacho drive. The dates of these style of engines was up to the late 60's yet this is a 1978 boat, so that does not make sense either. Later engines placed the pump beneath the injection pump, but these engines do not have the necessary aperture into the flywheel casing.

Had I bought her I would have investigated fitting an additional belt drive adjacent to the alternator, but now that is for some else to think about.

So the cost risk of finding out in short order the engines will need significant investment is the reason I have pulled out. If the boat remains available in a couple of months, and assuming I haven't found something else then I would consider her again, but the price would need to reflect what I think she is presently worth, and that is nowhere near the asking price.
 
£16.5k each for 80hp cant be right.

But otherwise everything you say quite right.

Curious as to why those engines of that age are in that boat. Unless maybe Lehman carried on with the old block well into the Dorset 27xx years.
