Re: 115 johnson unsure of year

There was no 115 in 87.

Is it a crossflow or a looper? If it's a crossflow are the exhaust plates flat (between the heads) or do they have a hump towards the bottom.

That R number is a serieal number. A dealer can run it for you.

115 was made 1969-1985 then again starting 1990.


FAQ 17. I don't know what year outboard motor I have. Can you tell me how to find out?
Get the model # from the little plate on the motor's mounting bracket or; on earlier models stamped on the crankcase. Here is a link to the model year guide: "http://www.maxrules.com/ej_contents.html"

the number is a model #, no published, contact a J/E dealer they can tell you.

OK, are the exhaust plates bolted on with a bunch of bolts or is the exhaust and block one casting?

Can an amateur determine whether an engine is a looper or crossflow just by looking at it?

Yes. A looper does not have any bolt on covers. The crossflows have exhaust plates / covers, intake by-pass covers and water jacket covers all bolted on. (Lots of bolts) The loopers have no covers over the exhaust or intake areas nor a water jacket cover on the heads.

Not to mention the 90* looper is flat out a bigger powerhead.

hello again. big bubble exhaust back is bolted on with many bolts (exhaust and block are not part of one casting).

note: i would not be suprised if the engine cover is not original (iow... maybe not a 115?)

Thank you

Good Morning,

Any thoughts on what the year is? Recap: V4 CF (bubble back with lots of bolts and jackets on heads); cover says 115 Johnson; VRO (with tag that says ethanol safe).

Tag with model # missing.

Thank you,

Could be a 1985 or later 115 which is the same as the 1984 140. The 110 and 112 are the same also.

Re: 115 johnson unsure of year

sounds good. i see when purchasing parts, i'm in a pretty wide range of years for a 115 carb rebuild... 1969, 1980-1995

amazing. i'm much happier working on this engine as opposed to the 125 force laying next to the boat now

Re: 115 johnson unsure of year

The carb kits will be the ones for the 1980-95 (from your list).
