used marine engines

If you are fitting another engine then if possible sell your old engine in situ and running even if a heavy smoker it will fetch more than a lump on a pallet could go towards ancillaries.

hi all, I'm looking to replace my centaurs old engine. I have found a company called marine enterprises ltd near Dorchester selling used engines. If anyone has any experience good or bad with this company I would appreciate any advice before I depart with my hard earned. Not looking for a war and piece report just whether a good company to deal with or not.
Kind regards and thanks in advance.

I have used them recently. I bought a Bukh from them. Email me.

Have to agree with the Volvo heat exchanger bit, even on my own one engine the Volvo part got slung over the side in favour of an off the shelf bowman. Remote fitting also made getting to the starter and that side of the engine easier.
Also agree that a much later engine should be more refined (lighter and more compact).
Electrics are electrics, starter/alternator can be changed almost endlessly.
The later breed of ecu controlled injection systems on some of the new engines that have multi pin plug connectors on a sail boat just seems ridden with potential problems. I would still like to keep things as simple as poss on an engine that is usually below water line in a salt laden atmosphere.

I've no personal experience, but have heard good things said about them, including on here.

I am very satisfied with my 46bhp model and it was actually cheaper than marinising a 1.8L Ford engine that was done by another forumite. (I did pm the OP about them as I am aware I am sounding like a Marine Power salesman or on commission, neither of which is the case)
 
When this thread was running, T had just bought a Thornycroft T90 from Marine Enterprises who packed it up and sent it to Portugal.For multiple reasons, it was not fitted and running till this month. Sean, whom I dealt with, was extremely helpful,giving me as much of the engine's history as he could.It replaced a 42 year old Volvo MD21A an engine that Volvo no longer support so any parts(marinising) were horrendously expensive,if available. The RB 2 g/box was a Volvo beast which I had already replaced parts on from another box and they no longer support hat either.
The T90 came complete with PRM g/box all for £1590 + £200 shipping to Portugal. Its first test was a 2hour run,its second 11 hours. Runs like a sewing machine and is exactly as was described by the company.I would recommend them wholeheartedly.
Extra costs in the region of £i,OOO were involved in fitting and special thanks to SANDYMAN of this parish ,without whom I would still be trying to get the electricity to run uphill!
So for around £3000 I have a reliable engine that parts are easily available for---- Marine Enterprises now have the manufacturing rights for Thornycroft.
 
Yes, I do know this is an old post, BUT I need to know if Marine Enterprises Ltd still have a very good reputation. I'm close to ordering a full reconditioned BUKH DV 36 RME with keel cooling and hand spring start backup to a normal 12v starter. The present plan is to buy one within the next few months, then fit it later this year to TNLB Elsie May, a 27ft alloy lifeboat.

The only other engine of interest, is a new 40 hp Thorney Craft, as they also match the RPM, Speed and torque curves for a full displacement lifeboat. That engine was fitted to the 37ft RNLI Rother class, which was the last of the classic wooden hull full displacement lifeboats. The RNLI does know which engine manufacturers make the most dependable diesel engines, so I'm pleased to see they are back in production.

The yard my boat lives in fitted a second-hand lifeboat engine (Bukh?) from there shortly before they fitted my Nanni. They said it was in very good condition and very cheap.
 
These people are mentioned regularly on the forum and I have not heard anything negative about them.

I fitted a Bukh (24) from them a few years ago and was very happy with the engine and the service.

I bought a Bukh 24 from them early last year, in exchange for my old Bukh 20. A smooth transaction.
 
When I bought my boat around 7 years ago it had the original Perkins M30, so around 27 years old. I noticed in the paperwork that came with the boat that the engine had been rebuilt by Golden Arrow marine in around 2005, there is no hour meter on the engine so I didn't know how many hours she had under her belt, a quick phone call to the number on the receipt told me that this branch of golden arrow had been taken over by another outfit whose name escapes me.
The guy was very helpful, he even found my engine in their records, it had had a full rebuild. He said to rebuild it now to that standard would cost more than an equivalent beta marine engine. He even took the time to email a parts needed list and cost - labour.
Edit.
Just noticed the link to Marine enterprise, these prices seem very reasonable, something for me to think about in the future.

We re-engined 18 months ago. Centaur MD11 to DV24 from Marine Enterprise. Great decision. Recommend. The fit is tight, as the engine is both higher and wider, but doable. As an ex-lifeboat engine, it almost certainly will be low hours and regularly maintained (and 'exercised') to operator standards. The key is that they are keel cooled in the lifeboat, and therefore whatever the age, they have had no exposure to salt water. Kind of zero hours. Different water pump therefore needed and a brand new unit was fitted as part of the cost. Sean is excellent and a pleasure to deal with.
If it is of interest, we had the work done at RidgeWharf near Wareham. A good choice, and a nice trip if youre around the solent area.

Your 2020 is an entirely different animal from the old Volvo made engines I was referring to. However, even though your engine was current until 9 years ago, although consumables are relatively cheap and easily available, you will discover if you need to do major work, that not only are the Volvo marinising parts such as the heat exchanger, but also the base Perkins engine parts are hideously expensive to the point that if you need basic repairs such as a rebore or crank regrind it is uneconomic even using Perkins parts. These engines are not designed to be rebuilt, but as they typically last a minimum of 8000 hours in normal use this represents over 50 years of typical yottie use.

Agreed. Even mores so with the 2020. I have this engine in its Perkins M20 form in our Sabre. What's interesting is that even Perkins didn't make this base engine, it was imported from a Japanese manufacturer. Eventually they went in to a joint venture to make this engine in Peterborough with imported Japanese parts, but not before the late 90's. The end application for this base engine was various, going into generators, forklifts, diggers etc with tonnes of OEMs. My guess is that it's possible to get base parts for these engines outside of Perkins or the marine supply chain if you know what you're looking for.
