Thanks for that Paul,
Very interesting, definitely the heavier end of Lister Land!
'Round about 2002 I worked for the bloke that bought HMS Beagle, the last of the RN hydrographic ships that were painted white (they ended there careers in grey, with a number on the side so it looked like we had more war canoes!)

After the conversion she became MY Titan and is still working the Med

We pulled the genny's, two went for scrap and two were shipped to New Zealand where the ex HMS Bulldog was undergoing a similar conversion.
I would have thought that there's a market for your motors, if not as genny's, there's still a lot of ex fleet tenders and tugs running the fours. There used to be a chap out Norfolk way who reconditioned them, maybe he could help you place them. If you can't shift them let me know and I'll ask my mate, Westy, who was the Chief on the job, if he can come up with a lead.
