172 diesel marine engine ??

Operator4100 · Feb 6, 2019

I recently acquired a 4 cylinder ford diese engine from a boat
At a junkyard when I saw it I was like wow I know that engine
So I got it for a song, it has a transmission attached with all the weird looking marine parts attached to the engine, engine not froze up so maybe a good engine, was wondering if you guys had ever seen one before??

Have not seen one but not surprised that it was used for marine service. Probably came out of a wooden runabout. I know Chrysler 6 cylinders saw wide marine use and the 283 GM V8 was used in wooden runabouts

..and in Bayliner fiberglas boats inboard/outboard config.

I had a 17' long fiberglass jet boat with an Oldsmobile 455 V8. The boat weighed less than the engine. It could do 70 knots, but only when the water was smooth as glass, otherwise it was too rough of a ride and would beat you to death. It could easily do 45 to 50 knots in most conditions. It was great at pulling up novice water skiers as long as they could hold on. It was the only boat I could ever water ski behind while barefoot.

water pump is broken off where typically hydraulic pump mounts but couldn't see any damage to the block

Is there a tag on it like the ones on the industrial engines used in generators and pumps?

Nice find.
A friend of mine had an old Chris Craft.
It had two Hercules 6 cyl flatheads in it.
The engines were built to spin in opposite directions. I wonder if they ever did that with those Fords.
Would be a heck of a note to install one in a tractor and discover you had 4 reverse and one forward.

Casting numbers? Are you sure it's not a 192 diesel?

Operator4100 · Feb 7, 2019

I should be getting casting # and tag # today and will post them, no I’m not sure which engine it is but will be checking to see and let you guys know

I'm curious. I used to get marine engines Chevy 250-6cyl and 350's for use in racecars. The blocks were heavier with meatier webbing, had forged cranks with 4 bolt mains and stronger rods. Stock or racing parts bolted right in. Wondering if that was done to engines like the OP is talking about?

My father-in-law had a boat with a V-6 that was branded with Mercury on the outside, but it was basically a Chevy 4.7 Vortec but with a heavier casting and all marine grade steel inside. When he had work done on it he discovered that it had some stock Chevy parts and some you had to buy with the Mercury ($$$) name on them.

We had Mercruiser lettered on the rear of one the cars that had a marine block it was a good joke in the pits.

In a marine application with dual props, you almost have to spin the them in opposite directions. If you don't do this the boat becomes almost impossible to steer.

My former company sent an engineer out to figure out what was wrong with an oil rig. They had missed this detail and it was going in uncontrollable circles in the Gulf of Mexico. Modified one of the engines to spin the opposite direction and swapped out the prop and all was well.

ok guys got an update, tag not readable but casting # is CONN 6015J makes it a sleeveless block right? dangit was hoping it had sleeves, anyway this engine came from a sail boat so only 1 engine lol hopefully it will turn in right direction and not have more reverse gears than forward as the other guys stated lol

One thing about Ford is the part number tells a lot about the history/source of the item. Your find--C0 says 1960 design. NN is engineered by and for Agriculture products. 6015 says it is an engine block. J is code for this particular version of that casting. I just went to shop and checked the 801 has a C0NN-C block and the 4000 has a C0NN-J and it is a gas engine. Somewhere a while back, I came across a web site that gave a listing of the letters used it the parts id system, can't find it right now. I got a D6JL-A engine at local scrap yard with head and industrial bell housing. Engine was slightly stuck, looks like it could run again.

Kirk-NJ · Feb 8, 2019

Your casting number would be for a 172 late 1960/1964

Kirk-NJ · Feb 8, 2019

Your D6JL would be a 172 built in '76

Mercury admitted to purchasing Ford and Chevy blocks and using mostly their parts in the buildup, as it made financial sense. Reason for swapping some
of the parts is that being a boat engine it's built to run at redline all day long. An automobile engine isn't (speculation). Other considerations are fire safety
since they are usually located in the bilge area where fuel fumes congregate, unlike an automobile, and the fact that marine engines use spark arrestors but
not air intake filtering. Then there are the exhaust systems that have to be water cooled; again fire prevention and on and on.

ne hand washes the other, I guess, because, Mercury Marine built the dual overhead cam aluminum engines for the first generation ZR-1 Corvettes

Judging from the picture, it looks like it was "fresh water" cooled (i.e. closed system). That's good because a raw-water cooled engine in saltwater will quickly rot out.

Coming from a sailboat is good, too. It means it probably isn't reverse rotation, and it probably doesn't have a lot of hours.

All manner of small industrial engines have been adapted for marine applications. I've never seen a 172 in a boat, but it doesn't surprise me at all.

Texasmark1 · Feb 8, 2019

In recent and current designs, the propellers come in matched pairs, counter rotating...one is cupped to the left and the other to the right allowing a dual engine installation to use the same outboard engine in both positions and get the luxury of counter rotation by just switching props.

Operator4100 · Feb 8, 2019

ok guys this is where I'm at, this engine you fill the crankcase from the valve cover, it has a freeze plug in the block where you normally have the filler tube, do any of you have an old block that they would want to part with the oil filler tube, I'm sure you just pop out the plug but how is the tube installed?
