Re: Mercedes OM616 - looking for cruisers w/same

I have nothing useful to add other than I own a 79 Mercedes 300D with the 617 chassis and it is my pride and joy. I only have 200K on her and know for a fact the car could easily outlive me despite my relative youth. Parts are abundant and cheap online. Good forums for repairs too. A truly wonderful machine that is utterly mechanical and thus repairable.

Our sailboat has a boring Universal 5432 (M40), which is utterly reliable and uninteresting by comparison.

Re: Mercedes OM616 - looking for cruisers w/same

I have a OM616.912 fitted in my boat, a Compass 47 that I bought three years ago. I took the engine out and had the block re-built and bought many ancilliary parts from various sources. If you are looking for technical advice, you might have a look at the DMV Bootsdiesel website (Germany). The guys there are happy to answer any questions you have and they speak English. In England, the company I used for the block re-build was Crewe Engines, who specialize in Mercedes engines. I have lots of further information about this engine as I have done a lot or research on it. I also have a complete workshop manual if you need any specific tech data. To my knowledge it is a good, robust, hardworking engine that should give years of service and spares are availale worldwide, just think of all the 240D taxis that there are all over the place all with is engine, many with up to 300,000 miles on the clock.......

mightyhorton A lot of Passport 40s had the Mercedes 636 engine, marinized by Nanni. There is a lot of info on the PassportOwners google group about these engines, and some guys that have lived with them for many years.

aeventyr60 Try your google search in England and Europe, Many boats outfitted across the pond with MB engines. I got some perkins parts from an MB parts distributor from another euro cruising friend. Sorry I don't have the link for you. Most have had positive reviews on the MB Dad got 500k out of his 240 D engine...

Also, the primary fuel filter will be available at your local auto parts store, cross reference the OEM number, most likely FRAM will have a part number.

There may be a small copper compression washer that helps seat the injector. Check if there is one, some times they get smashed and don' t seat.

good luck!

Mercedes OM636

We have a Mercedes OM636 (38 or 42 Hp) on our Voyager 35 ' a 1977 UK boat. We were in Toronto when the original post was written but we have gone down the St. Lawrence and are currently in Halifax. We met a guy in PEI with the same engine on a boat of his that is down in the Caribbean. He also said that in the US parts are available from a refrigeration truck company (damn I can't remember the name).

sealover Hey brush up on your Czech and try this: MB.BOLINKO.ORG - Dok. serwisowa CD2

It's for cars, but it's very thorough. Good thing to have bookmarked if you own anything Mercedes-powered.

The site navigation stuff is in pig latin, poorly laid out, confusing, and sometimes redundant but the manual is in English. It was originally a program burned onto two discs so you have to click back and forth between CD1 and CD2 to get where you're going.

I frequent a cheap U-pull-it junkyard that usually has some 123 and 126 diesels, if you need any used parts from a car motor let me know.
Sorry I can't be of more help.

Mercedes OM616 - looking for cruisers w/same

As it rare to find boats with marinized Mercedes diesels onboard, my Celestial 48 has one. The original primary enginge for the boat, provided by Nanni-Diesel in 1986, original information, specs, shop manuals, just general information is scarce.

This is the Mercedes OM616.912 (or marinized Nanni-Diesel 4-242) 72HP diesel engine which powered old merc. truck and cars.

I'm looking for other sailors with this type of engines to share stories, parts sourcing, maintenance and fix advise.

I am currently looking for the model # of the primary fuel filter and some advise to fix a fuel leak around one of the injectors. If by chance you now of a good Mercedes diesel mechanic in the Toronto area that will make house calls, it would be most appreciated......

Thanks and please advise.
