well here she is!

i had a ad on craigslist saying that i was looking to buy a 100-130hp motor...this guy emails me and says..

"I have a '93 Johnson 140 you can have for free if you come get it. It has good compression and runs strong but tends to run hot. It has a 25" standard rotation shaft and include a prop. I used it often on my Chesapeake 22. I put a bigger motor on my Chesapeake so I don't need it now."

well i send him back an email saying hell yea i want it ;D but the soonest i could pick it up was this weekend....i went to harbor freight tool store this morning and got a great deal on a 1 ton engine hoist $109!!...without the net special and 20% coupon its normally like $167 with taxes....anyway..my buddy meets me at the house, i call the guy and he says motor is still sitting there to come on out!..we take off and go..... we get there and using the hoist we make short work of loading it......the guy said it was running with he took it off the boat to repower but that at certain speeds the overheat alarm would go off but if he backed off a bit or went over that speed she ran cool......he said he brought it to a shop and the mechanic said he couldnt find out why it did that...he had lower unit rebuilt and complete water pump changed 1yr ago.

other than alil corrosion on the lower transom brackets she looks to be in great shape..i was really surprised he gave this away..but who am i to question his generosity or motives? ;D he lived in a nice house on the water so i'm guessing he is not gonna miss the motor or the cash....he was just happy to have it off his garage floor :).....oh yea..that hoist paid for itself 10x over today...my back is thanking me!!

here is the model number.. could someone confirm that this is a 93 model for me.. nada leans towards a 94 model at 378lbs!.....J140TXERR...s/n G 03522499

its missing the controls and wiring harness..so i'll be needing to find those..and a lifting eye and jackplate so far...i'll get a compression check on it as soon as i can get it mounted on stand and figure how to do it without a wiring harness.

heres the pics!

Awesome! Looks great! Change the thermostat/s and see what happens.

J140TXERR is a 1994 model year.

J=Johnson
140=Hp
T=tilt/trim with electric start
X=25" shaft length

next 2 numbers designate the year. For all OMC's

I=1
N=2
T=3
R=4
O=5
D=6
U=7
C=8
E=9
S=0

So; ER = 1994

Great looking motor what a deal i got one of my 140's the same way except yours looks better outside by a ton. change the northern *t stat covers for southern covers and it will run cooler. that motor is built for the north.

Southern T stat covers with head over flow.

Northern T Stat covers no over flow or tie lines

see here the t cover has hoses connecting them and one leaving to the pisser on the motor lower cover

hmm..hopefully that does the trick!...got a few things to do before i get to that part though.... i was just looking at it ..it seems like it was rebuilt before...seems like the powerhead was painted and there is a "020" stamped right above the V4 on the back of it right under that round plug thing.....i pulled the plugs and 3 of them was totally clean....i'm thinking water getting in a steam cleaning them?..the bottom right was black and oilyish...i guess i wont know till i get a comp check done on it....

to do that i need to mount it on my stand ..which i need to modify a bit....then i need a lifting eye...hows much do these run and what is best place to get them?...next once its mounted i got to figure out how to turn it over without a wiring harness/key..any ideas?...what is the best manual for this motor to get me started..cylmers or seloc? eventually i'll get a manf. service manual.

also..i dont see a oil tank, he gave me one but i dont think its for this motor..its too big to fit anywhere on it.....is this a VRO? or is it a mix ya oil and gas type?..i have a full tank of gas that is mixed...hate to throw it out....also kinda like the safety of knowing there is oil in gas.

looks like i might be in for some work with this motor lol but i guess for the price i can afford to put some cash into it and i got all winter to tinker with it.

oil tank goes in the boat somewhere and has a hose and wiring to the motor.the lifting eye i made mine out of an old com-a-long, the manual go ahead and buy the factory service manual for it, save money don't buy those other crappy ones. just get an "ER" factory manual. and as the turning over just hook the hot to the starter lug for the hot wire from the relay and the touch the the block where ever with ground she will turn over if the starter is good. it will havefire at that time as well so remove all plugs so it doesn't try to fire up on ya.

Kajun · #7 10-15-2006, 04:08 AM

ok i got the oil tank then...i'm thinking i'm just gonna leave it it off for awhile...less to deal with atm...

got a pic of your lifting eye? i can weld(tig) and i got access to welding machines, machine shop and other things so i could prob make it.

i'll buy the factory manual.. ebay?

do ya think i could do a compression check with it laying on ground like it is? i'm dieing to know if this thing has compression lol..especially before i go out and buy all kinds of things for it.....i'll pull all plugs, connect them to plug wire and then ground each one not being tested.

Compression Test: * I'm no experienced mechanic - *but I dont see why you couldnt test it lying there. * *If she is steady and wont rock over - *go ahead. * Verify the shift mechanism is in neutral, remove the plugs, open up the throttle, and crank her over. * I would see if you could attach some battery leads to the Starter and ground. * If you make/break your battery connection at the starter numerous times ... *the voltage arc starts to eat into the starter lug. *At least that was my experience.
Good Luck - I had an '85 90hp version of that engine which I sold this spring. Motor ran great for 20 years - with not 1 thing ever going wrong.

You did good on getting a Freebee. Good Job ! ;D

TheTinMan · #10 10-15-2006, 09:25 AM

Can't you just hang the motor on the transom instead of using a stand?

I also think people rely too much on compression tests. I bought a 90hp v4 Rude, tested the compression and it was fine. Could not get it running smoothly, pulled the heads and one piston spit a ring, piston had 2 rings and 1 was still intact so compression was good. Compression tests are not a guarantee the motor is good...at least in my case :-/
