OM617 First Start:)

Those old Mercedes diesel engines were built like tanks. Good old fashioned tractor technology. They don't make 'em like they used to. A nice choice for the Bayliner.

The tear down and rebuild would be great content! Looking forward to seeing this.

That's the go to for old Toyota trucks!! My 1990 will have one someday

They way it ran I was thinking it needs injectors. I waited to comment to see if you thought that too. These are great engines though. Can be made to do big power. Some of the best engines in the world. Cheers, Ard

Nice runner, sounds like shes still got some decent power left in her too

It is a very nice engine.

I look forward to seeing you tear it down.

bout 10-15 seconds of glow, good prime, and it will kick over every time. I've got one of these in my 1963 unimog 404 with a claimed 250k miles and it runs like a top.

Go ahead and do a vacuum pump delete and pull the valve cover off to check chain stretch. The vacuum pump vents directly into the crankcase so deleting it will get rid of some of that blow by.

Yeah a set of rings and bearings. Touch up the cylinder head. Will give plenty of care free hours for your boat.

PCV on top of valve cover is not connected to intake manifold, it looks capped with hose clamp... that will make crankcase pressure build up.

I've got an OM 603.75 that is on my to-do list. It needs to set of cam followers and injector nozzles. These old engines are built like a tanks. Supposedly the one that I have is the least reliable. But it's odometer has rolled over and cranks over every time.

i have this engine. it runs great on waste atf

Oooh the bayliner swap should be an interesting project. I assume this won't use seawater in the cooling loop?

Is that actually bad blowby? Im used to old Ih and jd agriculture engines, and thats not bad. May a fresh turbo and injections and some seafoam for the 1st oil change..

What engine is in the Bayliner now?

I love these Mercedes diesel engines so much! Theres s guy in the UK whos got a YT channel too, check him out he pretty much exclusively a MB diesel builder, tuner, full-on die-hard enthusiast. @DieselPumpUK is his channel. If you need anything for this or any OM606, 605, 617 etc hes your guy to see! He even sells drop-in full 605 &606 crate motors ready to go with turned up high pressure fuel pump & totally mechanical too! Id love 9ne of these things....along with 10+ other beautiful diesel oil burning torque monsters! I want one of each of the real good diesels from 3406b on down to a 4bt, maybe even a 2.0 LUZ from a ('14 -'15)Cruz! I got problems, i know!👍🏻👌🏻⚡💥💨🚜🛠️🔧🔩
