Older Johnson ID by serial number only

Hello.

 

I'm looking to purchase an older Johnson and the only visible number is the serial number stamped on the plug on the engine - G4392275.

 

I know nothing about the engine, but the cowling says 140 Johnson, its a looper, has OIS, and that's about it.  I can dig up some pictures if necessary, but I'm hoping one of you can work some magic.

 

Thanks in advance!!

If the motor is a 140 HP, then it does not have the OIS ignition system on it.

 

Can you send images of the motor cover decals and of the engine block from the sides and the back?

 

We may be able to help you identify the engine from those.

[ Edited ]

I apologize for these terrible photos, but it's best I'm getting from the seller.  The following link has 7 pictures of the engine, unfortunately non of the cowling.

I'm looking to inexpensively replace my '97 Johnson 115 after it decided to eat some rings.  He's posting this as a 2000 Johnson 140, but that's obviously incorrect.  He is unable to find the engine tag with the model number and he knows nothing more about the engine.

 

He wants $1500 for it, claims it has 115-120 compression and runs great.  I'd go look at it in person, but it's about 3 hours away and I'd rather know exactly what it is before I make the trip out there.

 

Thanks for your help, it's much appreciated.

That is either a 90 or a 115, not a 140

Any guess on the year?

Re: Older Johnson ID by serial number only

Also, as an aside, what are the chances of successfully mounting an 80's Johnson 140 (bubble back) powerhead in a 1997 Johnson 115 (also bubble back)?

 

Like I said, I'm trying to replace this bad powerhead, and I found an older 140 powerhead only for very cheap.  I've checked the powerhead adapter gasket, and they're the same - 342513.

Re: Older Johnson ID by serial number only

That may entail some customizing and rewiring.  You may end up investing more in time and additional money making it uneconomical and a jury-rigged motor.
