this times.... aghhhhhhhhhhh.. engines...

what do you have..
how has it been for you (darling) /forums/images/graemlins/blush.gif

would you recommend it....

etc ad infinitum..

there are MANY boats out there, and MANY engine installations.. some are deliriously happy with the setup, some are not.. some are constantly being fixed (often innapropriate use, but sometimes design and fit for purpose issues)

In our Seastream, we have a Mercedes unit with BW velvetdrive box and after 2.1 reduction.
the engine is an OM636, actually, an SM636.. mercedes 42 HP made in spain, under license form Merc.

superb, relaible to the nth degree.. the BW is bulletproof, as is the engine, Bowman / Jabso indirect conversion.. the engine is opriginally a 50's design. from a Mercedes 170D.

heres the "car" from which it was derived...



and some general shots on a crate..





a great, HEAVY lump, that keeps on going.. not expensive to rebuild if you needed to, and spares available..

Joe.
 
Volvo MD17C, I believe the last marine engine built by Volvo. Heavy, not very powerful, solidly built and will run forever. Spares still available.

Out of interest, five years ago I asked Volvo how much it would cost if they were to build a marine engine to the standard of the MD17 today - £16,000 they said.
 
Yanmar 3HM35F Cap'n.
Hey, those are nice bits of wood under that engine of yours! And you've got excellent access all round for servicing, too. Wish my dipstick was as easy to get to.

PS You shouldn't refer to your good ship as a crate. It's rude. /forums/images/graemlins/blush.gif
 
Yanmar 2GM20, incredibly reliable, has run for 19yrs with minimal servicing. In fact last year I had to replace the rusty engine feet and the engine went straight back in with a few new ancilliaries.. On it's third water pump. Planning to replace with the newer three cylinder model, 3YM20 I believe..
 
Be careful where you rest your case Dave, most airports will do a controlled explosion.....

it is YOU who is doing the pissing, and unfortunately, into the wind.. threads like this SHOULD give you the insight into what works and what doesnt.

cruising allows a modicum of release from such emotions. its only booody students at uni wih preconceived... blah blah... done that one...

Nurse, me Zimmer n me steady pills .. and can you give the ol fart in the corner one as well ???

Old, well, we are talking outlook, not physical... Dave, me nurse offers ya a nice shiney ali zimmer to lean against an contemplate...... /forums/images/graemlins/wink.gif, take it, you will be far more at ease.... and the GT model has wheels, new fangled stuff I know, but it makes granny go balistic
 
Started med cruise 2003 with Volvo MD17D but it gave up in South of France spring 2005. Fitted Yanmar 3JH4E (3 cyl - 39HP) no problems with the Yanmar so far. Note: the Volvo was raw water cooled and this led to it's demise as the cooling water passages slited up which led to over-heating and ultimately damage to the pistons or at least the oil control rings - I could have rebuilt it but it would still have been a 20 year old engine. Also note the decision to change from Volvo to Yanmar was due to the high cost of Volvo spares - I have since found that Yanmar are even more expensive and forbid their US agents from supplying to Europe - some spares are lass than half price in the US.
 
You don't seriously expect people to post here that their engines are super and reliable and never break down and.....??
 
Two boats with Volvo 2003T no problems apart from a fractured bracket for fridge compressor, I think that was yard manufactured. Fixed in Venzuela for a few quid. Over 500hours on one without a problem and must have been 200 on the other. Both sail drives only problem was the volvo folding prop design which has since been improved.

Compact, economical, easy to service, reliable.
 
BUKH DV10ME. 25 years old. A well made "proper" marine engine but extremely heavy and takes up a lot of room. It runs quietly and with minimum vibration. Also it does have the advantage of a starting handle; very useful with only one battery on board!

Would I replace it with the same? No, probably not. I'd go for something lighter and smaller.
 
I hope not David, I rather hope that the ones that cause issues, or owners who have found issues with spares etc can be highlighted for others.. usually, there is a way around the spares, many are available for the source engine, but not marine, many heat exchanggers, for example, were made by firms like bowman, and can be obtained, the gearboxes are usually of limited types, hence spares etc.. also, marques are often not what they seem, I belive the very old 4 series volvo was in fact an om636 for example. I have seen posts on other forums and articles in mags saying things like, allow 10 k for a new engine etc, often not needed, sometimes needed.. and "no spares available" etc.. often again not the case. if the thing proves unreliable, it is interesting to find out why. as it can be such a percentage, potentially, of a boats cost, then yes, I think it is both interesting and important.

Perkins 4.108, 1987 model.

Old fashioned oil seals mean that the dear old things drip oil after about 1,000 hours of action. Popular with the fishermen around Kalamata, who seem to get about 10,000 hours out of them, but they do look after them well. Never ask them to pass the bread after they've been at sea though - the black finger prints add just a bit too much flavour.

Mine quit at 5,000hrs with a piston ring fracture, but I know it had a flaky maintenance history for its first 2,000 hours. Rebuilt for €3,000 by local Perkins engineer (and he did the lift out and re-install, which is a real pain in an Oyster 406).

Moral? Have a diesel which fits in with the local agricultural community's choice. Agricutural diesel repair and maintenence is superb value for money - well - certainly in the east Med and N Spain.
 
OM636 - sitting in a shed at the moment looking rusty and oily before the refurb /forums/images/graemlins/frown.gif

It took a bit of thinking to get it out of the boat, but from the pics I can now see where to fit lifting points!
 
lol Damo, have you found Westsfield 4*4 in Lancaster, great stock of 636 parts, I also have a contact for Graham Gott who used to be some head honcho at merc and knows the 636 inside out (There are loads of them in some unimogs, airport tugs and later they were used extensively in refrigeration units in trucks), he has sheds full of parts if you need his number.. there is also a workshop (Gen Merc) manual available, had to get mine from the states.. if you need any info from it let me know. In spain it was also made as the Sol Diesel SM636 and there are loads about here.
Joe.

Jim, good points, a few companies worth checking are asap and lancing for 4107 and 4108 bits if you need them. Huge stock of marinisation parts too inc heat exchanger for almost every conversion done.
 
Six Cylinder 125hp Lister Petter CD6 by Beta Marine.
Have used it for around 1500 nm since we bought the boat. Only problem to date was caused by a failure in the anti syphon. Still managed to get all the water and oil out and recover.
Main problem - 25 litre oil capacity, which can prove expensive in some parts!
PRM 750 box.
Box got v hot in the Adriatic. Its pump needed replacing (at about 400 engine hours). Parts flown out from UK to Italy.
All very robust kit thus far.
