Re: 1988 johnson v6 vro info

Now note, this motor in the pic is mine. It is a 1991 big bore block with a 1987 small bore ignition system and carbs. I found the magic frost plug that told me what block I had up under the bottom of the block. So until you find the magic frost plug you will not truely know what you have.

On the 1988 power heads, the plug is located where I described. Same location on the 1986 and 1987 power heads. I have all three years of power heads.

Re: 1988 johnson v6 vro info

Greg, I did find what I belive to be 3 plugs on block. One center top two, lower bottom. No id #'s May have been changed out. I do have 2 power packs like the first pic shown JK.
I'll take a couple more "close up" pics today after I get back from work.

Re: 1988 johnson v6 vro info

Interestingly enough yesterrday I did begin taking numbers off power packs for searc/id.
The numbers were; CD6L{6700}583605

Re: 1988 johnson v6 vro info

Greg, JK,
Just got off the phone from the fella who sold me the engine. He talked to the marine mechanic who sold him the motor. Same comment, go to top of spark plug block and scrape off the paint on the freeze plug for the id. I'm gonna do that right now, the paint was pretty thick so maybe it is there.
But on a cool note the mechanic says the motor numbers are; J 225 PXCCB. Finally something to work with. And Greg I did read your new thread about the catalogs, makes alot of sense to me. Let me know if you still want me to shoot over pics.

Re: 1988 johnson v6 vro info

The model number the mechanic gave you indicates that the engine is a Johnson 225 with power trim/tilt 25" shaft,1988 model run B.

The fact that you said it has two separate power packs would indicate that the powerhead, or at least the flywheel, timer base stator, power packs and engine wiring harness are from a 1986 or 1987.

The freeze plug I'm talking about is on the back of the block about two inches down on the center line of the engine. You can't miss it. There is nothing else near it. I've owed 1, '86, 2 87's and two '88's. All of them had the model number stamped into that plug.

Take some better pictures and post them. Take some from the back.

Also, the above water exhaust port on the back of the engine is different from 1986 to 1988 (Not sure what the 87 had) The '88's have a large oval rubber grommet that is sandwiched between the two halves of the pan. The 86 has a hard plastic molded piece that screws on. That won't tell you what the powerhead head is but it will be a good clue as to what the rest of the engine is.

See if you can find a part number on the heads. The heads on the 1986 and 1987 small bore loopers will be different than the big bore.

Re: 1988 johnson v6 vro info

Greg, Thank you. Will do. Got home late and the weather was cold. I'll shot over the pics asap. I did sart to scrape off the paint form the freeze plug but my other mechanic has my truck tonight with the proper tools. I'll do that tom. also.

Re: 1988 johnson v6 vro info

Unless the paint was very thick on the plug it would not obscure the numbers stamped in it. I'm not hopeful that you will find anything. Perhaps it was changed.

The casting number on the heads and the style of the exhaust port might be the best clues.

I'm not sure this is going to help you, but it's worth a look.

Re: 1988 johnson v6 vro info

Greg,
The paint was thick as mud. But today I took a bunch of new pics for your review. I will be very interested in your comments. Like 16 pics. probably can send 4 or 5 per message.

Thanks for the video too!

Re: 1988 johnson v6 vro info

Heads are small bore looper which would make it an 86 0r 87. You didn't take a picture of the exhuast port on the back of the engine. If it is a hard plastic piece held on with two screws, it would confirm it is an '86 or '87.

Re: 1988 johnson v6 vro info

Post #29 picture 2 view of the back of the block shows the plug that usually has the model number stamped into it.
The electrical is '86 or '87 and the heads are '86 0r '87 so I would say with relative certainty that it is not a '88.

I don't know how to identify a '86 from an '87 without the model number. I think there are very minor differences. If you can't determine which year it is I would get the manual for a '87 It is a better manual, and more complete than the '86.

Re: 1988 johnson v6 vro info

Have to agree with Greg, it's deffinately an 86/87. A couple of other points...

Has original T-stat system with the water control vavle, That would be gone in a new york minute. (good thing I don't live in New York!)
Has had the heads off recently, Will deffinately want to peel those heads off and find out what they where looking at.
Needs a closer look up under teh edge of the fly wheel for melted tar like substance.... Indicator for faulty Stator (comon)
Needs a closer look at Regulator if the tar stuff is there under stator.

Other than that great motor, and lower units are pretty built proof. Just need to change out the gear lube every couple of years.

Good luck and ask away.

Re: 1988 johnson v6 vro info

Greg, JK,
Thanks. Alot of great info to dig into and review. So the motor number I was given; J 225 PXCCB is a little off?
And the book/manual I would want to get as stated prior is; "For 1987 you want 507619". I'll be putting her up on a stand this weekend and getting a manual to start working on her. I will also stay in touch.

Re: 1988 johnson v6 vro info

The heads are off 1988-1990 era 225,ignition off of a 1986-1987 ,my guess would be it is a 86-87 powerhead some how lost its heads.

Re: 1988 johnson v6 vro info

Wow, I understand parts are of course interchangeable to make operational. So I still am a little confused on what or how many different manuals I need to service this little Frankenstein motor. Any ideas?

I physically checked the casting number on one of my 1988 power heads and a spare set that also came from another big bore looper which was a 1991. The casting number is 333809-3

I also checked the casting number on a 1987 small bore power head. It is 331490, which is the same as those in some of the pictures the OP posted.

I have not seen anything on that motor to indicate it is anything other than a 1986 or 1987. As far as I know, any differences between the two years would be minor.

The correct manual for the 1987 motor is 507619. You have it right.

Go to http://shop2.evinrude.com/Index.aspx?s1=896d741g3asg6k5p4qeh3aime7&catalog_id=0&siteid=1 select 1987 > 225 HP and a list of the possible model numbers will be displayed. You can do the same for 1986 seeing as we are not sure if it's an '86 or '87.

You have not answered my question regarding the style of the exhaust port on the back of the motor. Which is it?

Did you ever get the paint removed from the freeze plug to see if the model number was on the plug? In the pictures It still looks like it has paint on it.

BTW, your fuel pump has been replaced, so that's a good thing. The outlet fitting on the original was brown and it was a three wire pump. If you look, I think you will find that yours has four wires. I think the pump with the gray fitting is at least two revisions past that.

You will want to go here to download and print the troubleshooting guide and DVA charts to keep with your manual. http://www.cdielectronics.com/technical-support-documents/ You will need a peak reading volt meter or a DVA adapter for your standard meter to properly troubleshoot electrical problems. You will need it sooner or later, so just get one now. The DVA adapters are relatively inexpensive.

Re: 1988 johnson v6 vro info

Yeah, my bad should of looked at the pics a little better 331490 is deffinitly 86-87 2.7 heads Im pretty sure i need my eyes checked now
