Need a marinized OM606? Here you go. - HoleshotHolset - 10-15-2010

Prices don't seem that bad compared to what you'd spend on most marinized engines.
Cheers,
Matt

What would marinized motors differ from regular vehicle motors.
Just a coating on the motor.

Most of the time, they're built a little stronger and better suited for sustained high RPM use - compared to an OEM automotive engine. They also have completely different (or no...) emissions equipment and software calibrations. They have the benefit of an unlimited supply of cool water - so they can run things a lot harder (and turn the wick way up...) and not worry about cooling.
I have no idea if these engines are any different than a normal automotive application. I just thought it was pretty darn cool to see a marinized OM606 for sale and figured I'd share that with the other Merc dieselheads.

Do not compare the prices to new engines,these are used and or rebuild
RE: Need a marinized OM606? Here you go. - yankneck696 - 10-15-2010
All of those engines seem to have heat exchangers (Raw water to cool fresh water/antifreeze), should have bass freeze plugs, indtead of steel, usually have a bit more of a torque cam (gas engines not sure of these), can be reverse rotation, marinized (screened) starter/alternator, many coats of paint, hoses worthy of salt water, water cooled exhaust manifolds & so on.... I'd like to find out if they do reverse rotation internally, or with the transmission, as I have a PennYan with RR & would love to slap a Merc diesel in it without the $2400 ZF reversing 1:1 trans.

Couldn't you just spin the prop backwards and get a reverse direction prop???
RE: Need a marinized OM606? Here you go. - yankneck696 - 10-16-2010
The boat is a PennYan with a tunneldrive, prop & ruddder in a tunnel. Rotation is gritical due to strut design & rudder placement. It has been done, but with greatly reduced performance.

I'd be inclined to think they use a reversing geartrain setup. I've never seen a 'small' diesel setup that way. They spin the really large diesels backwards in some cases...
RE: Need a marinized OM606? Here you go. - yankneck696 - 10-19-2010
I'm just hunting for the ZF 1:1 reversing transmission. When I get one at the right price, I'll start on an engine. Till then, the trusty 318 will perservere....

On a boat i worked on a few years ago in Svalbard, we had a 6 cylinder 2000 hp Deutz Engine. Max RPM: 240 RPM frontwards, 200 RPM backwards. That engine we had to turn backwards because we didn't have a gear or pitch on the propeller shaft.
You must have a custom cam shaft that you can move to change timing on the cylinders, you also need a special fuelpump. The camshaft is moved by pneumatic. The engine is also started by 30 Bar (435 psi) Start air.
On very old marine engines that where 1 cylinder and 60 liters they gave it full throttle just befor the piston hits the top position. Then they got a big knock, and the engine started to go backwards. These engines run at very low rpm. from 40-80. They where about 50 hp an 4-5 tons heavy
Most big boats now days have Pitch on the propeller to decide if they want to go backwards or forwards

On Detroit engines its just a matter of switching the idler gear sides from driving the cam gear to driving the accessory gear.
RE: Need a marinized OM606? Here you go. - George3soccer - 10-20-2010
Are the Detroit motors a common choice for marine use.

Some of them are 2 stoke, so they are very small en powerful.
My dad had one in his 16 meter Reketråler (google it)
It was a Compressor and turbocharged 2 stoke.. Nosy as hell, but very powerful.
RE: Need a marinized OM606? Here you go. - yankneck696 - 10-20-2010
I've worked on alot of Detroits in boats. Great engine. If you ever notice one that isn't leaking oil, shut it down & refill it immediately... Caterpillars are also very common, Mann is starting to get some good usage over here... What I want is the dang diesel Wankel I sawat the Miami boat show years ago. Can't remember who built it, but 6 lobes, 3 turbos & 7500 RPMs.... Dang !!!
RE: Need a marinized OM606? Here you go. - George3soccer - 10-21-2010
Oh wow. Sounds like a fun motor really. Any videos on that bad boy

Was that an OEM marinized engine - or something that was converted? I've hear of diesel radial engines and diesel wankels, but they were both used in military aviation applications.

RE: Need a marinized OM606? Here you go. - yankneck696 - 10-22-2010
It was all billet & custom. They had one in a 42' Sportsfish. 40-something knots at 6300 rpm. It was about comparable to a friggin slant 6. cruise was 33 Kn @4500 & fine control down low for maneuvering. They were showing it as a prototype & it did well. If the #'s were right when I was there, they were real efficient & powerful. Smooth & quiet. Weird when you know of all the force being exerted to move that pig so quick.
RE: Need a marinized OM606? Here you go. - HoleshotHolset - 10-27-2010
Yeah - moving a 42' boat at 40 kts is no joke.
