Does anybody know anything about these motors? Are they good, bad, ugly? Any info will be great, thanks.

Very good motor. Same as the Johnson I believe.

Suzuki makes an awesome motor. I had a 115 on a Lund I just traded in this spring for a Ranger. The saddest part of the whole deal was that this dealer did not handle Suzuki's!!! Bummer.., I am that sold on Suzuki outboards. (I got the Ranger with a Yamaha, which is not far behind Suzuki!!).

Another FM'er stated "just like the Johnson". The reason it IS just like the Johnson is because until 2006, Suzuki made ALL Johnson 4-strokes up to and including the 225. And when I say "made them".., I don't mean powerheads only.., I mean the literal entire motor IS a Suzuki with white paint and "Johnson" name on the motor. Go look at a 2006 140 Johnson and a Suzuki 140. Only difference is the paint and the name.

They are not a "good" motor as you are wondering, they are a GREAT motor!!!

I hear the 140 is pretty underpowered compared to similar motors, and that they have discontinued it in favor of the 150 for this reason. A quick google search will get you more specifics.

Suzukis are great motors, but this one is a bit of a dog. I would recommend getting the 150 if possible.

To be fair... I believe the 140 is the same motor as the 115, just amped up. It has 132HP at the prop. Which on most boats is fine, my Monark King 185 (walkthrough windshield fish and Ski) moves good and planes out fine.

My buddy has a 150 Yamaha and he has 162HP at the prop. But he paid for the 150 Yammy, which is a nice motor too.

I have a 2004 Suzuki 140 and love it. As Chode said, they don't make the 140 anymore. They now make a 150 that is a 6 cyl if I'm not mistaken. The 140 is a bored out 115. I would not call it a dog. It moves my 18'7" Alumacraft at 45-46 mph. It's a great engine. I've never met anyone that didn't love theres.

I would agree the 140 is a dog, in the sense its like a good hunting dog. Quiet, and always ready to go. Its all about what your after if you want the fastest around this isn't the choice for you. I have a 140 on a 1700 fisherman and it gets out of the hole pretty quick and tops out around 44 mph. A friend of mine has a 150 verado and it will go about 52 on the same boat, and I know these numbers would probably change with different props on, but I'm sure the verado would come out on top speed wise in most cases. Price wise it wasn't a close race when I was shopping so I went with the suzuki/johnson

I bought the 140 last year in the spring and it has been ok but I wouldn't buy another one for one reason.... When my lower unit went out this year it took 3 and a half weeks to get the parts to rebuild it.. the cost of rebuild was also 1000 dollars higher than a comprable yamaha..

I will give mercury a try next year and get a Varado...

The motor does run well and has only left me scratching my head a couple of times...

A wire came off the motor behind the starter and it wouldn't start (poor engineering on Suzukis part).. got it figured out on the water with a couple calls to the marina....

Also has (had?) a vapor lock issue in which when you run to a spot fish a while.. go take off, get on plane and the motor shuts down.. WHIPLASH... pump the ball... go again.. sometimes it happenes 5 times a day sometimes not at all... I thought it might be my boat but another owner was having the same problem... I put a new fuel filter in recently and it seems to be working....

The motor has 1200 or so hours on it.. the powerhead hasen't missed a beat..

The 140 is the same class as mentioned as a 90 and 115.. it is actually LIGHTER than the 115.. A VERY GOOD OPTION BELOW A 150 because of weight and price (3 GRAND LESS)..

I have a 18 foot Tournament Sport... runs 44 GPS SPEED with myself empty livewell and stainless prop (gets out of the water pretty good (nothing like a E-Tec but who want's to replace a powerhead every year and dump 40 bucks worth of oil in it every 3 days)(((why do they still make 2-strokes???)))

runs 37-39 with the aluminum prop 4 people, full tank, full livewell (16 walleyes grin).. jups right out of the water no problem

Good motor all around and Very Good value (6 year transferrable warrenty was a plus)

I lost my lower unit last year. The dealership where I bought it replaced it with a rebuilt lower unit. I had my boat back in 2 days.

With the vapor lock issue.. I haven't heard of this issue before. Could it be an issue with the gas line? Have you tried replacing the ball? Just a thought...

Anyway- maybe its not the fastest motor, but I wouldn't call it a dog. Runs great, VERY quite, good gas milage and it's priced right.

I owned an 04 (Johnson/Suzuki) for 5 years - absolutely loved it. BTW, on the vapor lock issue: If I squeezed the ball 'til hard, I never had an issue. If I forgot, then I occasionally would have the problem. I would buy this motor again for my next boat.

On the vapor lock issue, I was fishing with a guide this summer that had the same motor same problem. On his HSOforum he said the problem is now solved and this is what he wrote:

...after several hours of testing different areas of the fuel lines I found that while the engine was running if I reached way up under the rear casting deck and messed with the fuel line it kinda made a funny sound. Turned the engine off and messed with it a little more and it broke off in my hand. The culprit this whole time has been a corroded aluminum fuel splice...

So, maybe it is a corroded aluminum fuel splice?? I know nothing about motors but thought this might help.

    • BEFORE BEGINNING

      Before you begin, make sure you have a good strong battery and make sure it's charged up. If you have a bad or weak battery, you may want to replace it because if it doesn't crank good and strong, you are likely to get a low, inaccurate reading. Make sure your engine is warmed up to operating temperature(if possible). About 10 minutes of riding should do.

      First, take out the spark plug and thread in the adapter for the compression tester. Make sure you have the correct size adapter for your particular ATV. Slide your kill switch to the "off" position. Some ATVs won't crank over with the kill switch in the "off" position, so if yours is like this, then you will need to either unhook your ignition coil or ground the end of the spark plug wire to a good ground. You can use a jumper wire with alligator clips on each end to ground it. Next, make sure the throttle is in the wide open position. You can either hold the throttle lever with your thumb or you may be able to tape it or use a zip tie to fasten it to your handlebars to hold it in the wide open position. If you don't have the throttle in the wide open position, you will probably get too low of a reading. Also, if you are testing a newly rebuilt engine, the engine needs to have been run for, at least, 30 or 40 minutes or you will probably get too low of a reading.

      NOTE: Before you begin with the actual test, make sure the threaded adapter is screwed in good and isn't leaking any air out around it.

      ACTUAL TESTING

      With the throttle in the wide open position, push the start button and crank the engine over until the hand on the gauge stops moving. Each time the engine turns over the hand should raise a little more until it reaches the maximum compression of the engine. When it stops, that is your compression reading. This usually takes no more than 10 seconds. Try to avoid cranking an engine for more than 10 seconds at a time as this is hard on the starter and the battery. Now, push the relief valve on your compression gauge and that will reset the hand back to zero. It's a good ideal to repeat the test a couple or three times to make sure you get an accurate reading. On kick start models, it will be the same procedure, but obviously you will be kicking it over instead of using a start button. Worn piston rings and cylinder walls will increase the number of strokes it takes to reach the maximum reading. If you're kicking, it could possibly take as many as 10-20 kicks to get the highest reading.

      THE READING

      You will need to check your repair manual for your particular model for the correct compression specifications. See note below. Usually, an engine will run OK if it has at least 100 PSI of compression. Most engines will have somewhere between 100-250 and some as high as 300 PSI, depending on the engine. Sometimes they will run with under 100 PSI, but usually not very well. If you get a low reading, you can do a "wet test" to try to help determine the problem.

      If your reading is too high, then you probably have carbon built up on your piston and combustion chamber.

      NOTE: You may get a low reading on some engines because some engines have a decompressor assembly built into the camshaft. Check the service manual for your quad to see whether or not your quad has a decompressor assembly built into the cam.

      WET TEST

      If you got a low reading, pour about 1-2 teaspoons of clean motor oil down into the cylinder through the spark plug hole and do the compression test again. If your reading increases, then your rings or cylinder walls are probably worn. If your reading doesn't increase, then it's probably your valves. You could have a bent valve, you may have leaky valve seats, or your valve clearance may not be adjusted properly. Also, low compression can be caused by a blown head gasket.

      CAUSES OF LOW COMPRESSION

      *Worn piston rings or worn or damaged cylinder walls
      *Leaking valves
      *Valve clearance not properly set
      *Blown head gasket

      CAUSE OF HIGH COMPRESSION (stock engines)

      *Carbon buildup in combustion chamber and on piston

      NOTE: Compression testing is a good way to keep track or "gauge" the wear in your engine. When you first get your ATV or when you rebuild the engine in your ATV, you can do a compression test and then later on, you can do them periodically. This will help you determine the wear in your engine each time you do a compression test and will guide you in knowing when your engine needs rebuilding.

      This is about all I can think of. I hope I didn't leave anything out and I hope this helps everyone with their compression tests.
    • As dumb as this sounds how is this done?
    • Try a compression check. And make sure the choke is opening all the way.
    • They are not the best out their but for the price and your average person not too bad I guess, Its going to send lead to where its pointed. This is probably what is going to happen he is going to buy a package shoot it for awhile then start upgrading everything to how he wants it and it is going to end up costing way more than if he just built one himself how he wants it.  
    • Hello, well I convinced my brother in-law to pick up my buddies old 1980 185 although pretty sure he said it was bored out to a 200? Here is the deal it's been sitting for a solid 8 years. I know it ran fine before. Not the delema-----   It starts right up (he bought a new carb odd amazon) although it sounds like a jet with high rpms. Looked at the throttle cable that's fine. Floats are fine. So he plugged this hole in the air filter and got it to idle down although when he hit the gas wouldn't get any power. Read a few things online and they tell you to just bypass the filter box and all that so back to amazon we went to get one of those filters that mount right up to the carb and it's still the same issue..   I just haven't seen anything like this? Do you guys have any thoughts or tricks that we/he could try?! Thanks in advance
    • Hi Everyone,  I'm looking into buying my first true fish finder and I'm a little perplex with the mapping card situation.  I'm looking at Humminbird Helix 5's and 7's.  I'm drawn to the autochart feature.  From my understanding, you can record 8 hours of charting onto the internal storage, but, is there any native mapping included on the unit or do I absolutely have to get some sort of mapping chip, zerolines or lake master, or navionics?  Can I store data on a blank SD card?  I've been researching this a lot and haven't found any conclusive answers. Thanks everyone!
