Suzuki DF 140 overheat issue (The sensor fix!)

[@p3teytran]

I don't even have this problem yet but I appreciate you sharing so people like myself can have a heads up. That saves us a ton of time and money. You guys rock!

[@shanetichowitsch8794]

Great stuff thankyou for showing a decent no nonsense video that was straight to the point and I believe will help many people who have an older outboard with these issues,,BIG THUMBS UP👍

[@jonmenges2256]

Just got done fixing this exact issue and this video was super helpful, thank you!

[@PopToys2002]

Replaced my sensor yesterday - 2003 DF 115 apprx 650 hours - so far so good! Thanks again for sharing...

[@CypressSpring]

Got a 2020 df140 with 56 hours that has the same issue. Fixing to check this out soon

[@1234-s8i]

This is the same issue I had with my DF140 will try this fix tomorrow. Thanks Jim Daniels

[@gilbertrodriguez3317]

I have a brand new motor with less than 200 hrs and it’s overheating. Thanks for sharing I’ll take a look to that sensor.

[@hyungyongchoi1718]

Thank you for shaing this video! Glad you fixed it!

[@Bigstarlegacyranch]

You're welcome!

[@pecotodorovski200]

Great info, very helpful, thank you! 👊

[@jeremyrowe4339]

I love these engines, i have two Johnson 140 but they are Suzuki engines with Johnson cowling. With a book they are easy to diagnose

[@jibbymcbeet]

For those wondering, this is the exhaust manifold temp sensor.

[@JNick-kz2tc]

Great Information!! Thanks so much for diagnosing this!! (You guys are LIFESAVERS!!)

[@osbornebay944]

Thank you for sharing. Check the easy parts first then harder one's always.

[@roche1777]

great video i have a similar problem now got a question for you that's driving me crazy because my motor is overheating on the exhaust port on the top next to the telltale I'm having exhaust come out of there with squirting water as well that's not normal because I have two motors and the other one doesn't do that

[@martin_schultz]

Hi from The Netherlands, Lucky that your sensor reported an overheating problem! Me and my two of my friends (all three boats mounted with a DF140) suffered the same issue (in a 2 years period): all three engins had a crack in the cylinder head, likely caused by overheating. All three of us got no sign of overheating at all, no alarm set off. It was noticed due to the engin starting up running on three cylinders. Scary: the enigine numbers of 2 of the engins differ only 1 digit! Suzuki Europe denies any responsibility. Anyone out there with the same problem?

[@mariagraziafornasin8111]

Hi, what is the engine year?

[@martin_schultz]

@@mariagraziafornasin8111 2008

[@FreedomWon20]

does this sensor just screw out? would love to have seen it out?

[@PopToys2002]

Thanks for sharing - I think you nailed my problem - will install new sensor in a few days and give an update!

[@Teamsylvest]

Bob Watson did it work? Å

[@Teamsylvest]

Hope this will work on my 70 DF :)

[@Nitrox4me]

I believe that these art NTC sensors (Negative Temperature Coefficient) What resistance values do you check them for and at what temperature?

[@chrisforrester3092]

How did you change the oil cooler? I just saw on mine that the o ring is damaged and I need to replace it. Could you talk about taking the oil cooler off?

[@unrealinventor2006]

I have df 60 overheating light when idling for a short time .Just started doing this only at idle.I bet the same sensor is bad on mine. Water is pumping fine and is coming out warm. Thanks ! I will change my sensor first.

[@finecrazygunz]

Im new to the boat stuff. How do u know when the motor is overheating?

[@roche1777]

your totally right i change the same sensor and fix thanks so dam much

[@josephmawae4261]

Do you know the name of the sensor my df40 is doing the same thing

[@natetallarino4032]

Trevor..YOU DA MAN ..keep posting.

[@boashna]

thermostat will stay open when it stops working because it is a fail safe thermostat .. you can tell it is open by feeling the prop hub discharge it be warm and never gets cold and hot to indicating opening and closing . . most mechanics dont even know about a oil cooler behind the oil filter because it is not in the service book. I replaced my engine because I was getting oil in water with 600hrs on it . I wonder if it was oil cooler. the sensor can be cleaned as I have and tested per service book .

[@jwb017]

Shouldnt you get a check engine light if this sensor goes bad?

[@Obet22]

Thanks for sharing, I haven't changed the sensor yet on my df140, but I will let you guys know soon if the issue goes away :)

[@maiklpapa1982]

Hello. How did you check the block if it full of salt?

[@josephmawae4261]

Hi what's the name of the sensor i have the same problem

[@fabiodipinto659]

Hi, I have a problem on my Suzuki 140. Only the buzzer activates without the flashing light.... what does it mean? A thousand thanks

[@bouhitemkamel]

I need help please I have a problem with the engine 115 df Suzuki overheating and ringing and stop

[@itomardi1533]

How to know how many hour the engine running if they use analoq tachometer

[@boashna]

turn the ignition on and rpm will move if it goes to 3 it means 300 hrs and if it goes to 3 twice means 3000 .. no need to have the engine running

[@offcamber]

Giddy-up! Thanks fellas.

[@saulgarza2430]

I have a evinrude etc 225 at low idle it does great but when I get to full speed the engine overheat light comes on and puts me on safe mode already changed the impeller and have great flow coming from the "pee hole" lol......could it be my sensors to? even if I pulled them out and they look good.....is there a way to test them ?

[@keithsk-gaming9820]

impeller problems

[@moneeshravi765]

Overheat no problem only change impeller or thermostat or water pump after good

[@jwb017]

What sensor is that?

[@hyungyongchoi1718]

Thank you!

[@bafanagbl3716]

Good day I have my Suzuki 115 outboard one engine is cranking but don't want to start the plugs don't spark I bought new spark plug but still the same story. Advice pls

[@rankorogan]

Hello, I have Suzuki DF40 and 15 seconds after starting (and he is cold) it show me the heating indication one signal every 5 seconds. Did You have similar problem? Tanks

[@michaelparker3450]

Is there a name for that particular sensor?

[@robertolashley2608]

After going through all that frustration do you still rate the suzuki engine over the yamaha ,i thinking to purchase a suzuki 150 soon but am indecisive

[@boashna]

This is early version suzuki but chain on fly wheel and sometimes the warranty goes to 6years as an incentive or rebates sells this engine . .I liked my 2002 much better than my 2013 suzuki as it had some small issues .

[@roche1777]

man you don't have any videos or anything on how to remove the flywheel??

[@mconner262]

Sounds like all those things needed to be done anyways

[@salmonkiller2545]

How many hours on the motor ?? My df140 has almost 400

[@neckahlong8222]

I am having a similar issue with my df60. Check engine light is also blinking….I’ve tried it all

[@nahuelayala7988]

Wats the name of the se sir and parts number pls

[@Teamsylvest]

Hope this will work on my 70DF :)

[@vantomlinson4581]

Thanks for sharing..

[@MS-rn3bz]

Can anyone tell me which sensor this is exactly??

[@Bigstarlegacyranch]

@@MS-rn3bz yes, it is on the port side of the motor, tucked behind some wire loom. Most of them have a blue wire attaching them.

[@Bigstarlegacyranch]

I believe it’s part number: 34830-87J20

[@atefrahim3141]

I could not get max rpm on Sizuki df 140 some one know the reason?

[@danjohnson7832]

Hi I am getting my fuel in my oil . Level rising. And thermostat stuck open. Any one has these issues ?

[@drmarine1771]

Good to know cheers.

[@edwardabrahamiii3742]

Ill get a suzuki next but ill stay far away from the 140cc engine

[@bobbyraymedina]

Duly noted

[@dirkswart8950]

Thank you

[@douglasparise3986]

My suzuki 140 is leaking oil like the exxon valdez

[@joshrayner7423]

Should have put temp gun on tell tail

[@joshuabriones8990]

Lol same thing happened to a friend of mine with his car ac replaced everything and it turned out to be a sensor.

[@kyle734533]

i got a 2015 and ive battled a random over heat the whole time at 5,000 rpm i got just over 200 hours now and if i keep it 4900 or only run it for a short 3-10 sec it normally wont shut down and go it safe mode. but when it does i normal just turn it off for like 5 secs and it runs like new. Dealers have always BS the problem.

[@boashna]

nice to know

[@thisismecantuseeitsacz5823]

If you keep it turned off it won't run hot.🤔

[@JULIOZ06]

thanks

[@allosaurusfragilis7782]

Its the same in cars these days. Its almost always a sensor. I dont trust them.

[@eddietinoga5846]

thanks for the info

[@thediplomasta5891]

Get a thermal gun. They're ten bucks.
