Evinrude 140 Sport

[milkdud]

I would like to know more about this particular motor. I am an Inline 6 guy, and I do not know much about V-4's.

What year would this motor be? I assume cross flow.

What does Sport mean?

Are these 99 cube motors?

Any particular reason to like or hate this motor?

It is in very nice shape and I have the chance to buy it. If any of you would like to try and appraise it that would be nice. If not I understand. Motors are hard to put a $ amount on.


I appreciate it.

That one is a 1981 model. In my opinion it had one of the best color/decal schemes. The one in the the photo looks beautiful, almost immaculate.

I'd say that engine is worth at least $2500, or even more--of course, to the right buyer. As soon as my response pops up, surely someone will respond with a "I can buy 140s all day for $500".

It's cylinder displacement is 99.6ci.

The 140 Sport was nothing more than a color scheme by 1981. It is a 140, no more and no less. It's predecessors were the original 135 Silver Starflite (1974-75) and then the 135-S (1976) and 140-S (1977). These were sold with standard power trim and SST propeller, where the "regular" 135 (and 1977 140) had no trim and an aluminum propeller. From 1978-up, "both" 140s (the standard and the "S") came with trim. By 1981 there was no "standard" 140, the one in your photo was the only one available.


It is one of OMC's best engines ever, and will give your inline a run for it's money. Boat to boat, setup to setup the inline is likely faster by a mile on top, maybe a few even...but from a dead stop, the 140 will out accelerate it to the first turn easily.

It is a cross flow 99 cu in, probably '79. Sport meant it came with power trim and a stainless prop. I can confirm the year with the serial number

I paid $1300 for mine without a control box and it was not as clean as the one pictured. Mine is a '78.

Thank you for the great response John and 930turbo. The seller thought it was a 1984, but I did not know. I cannot find this sticker package when searching google images.

I dont think the motor had much use. It has been stored inside all its life. The owner also was the owner of the marina. Later years it was not used much. . It got winter service each year no matter if it was used or not. The guy was very particular.

Did this motor have a oil tank and mixing set up? Or was is mix by hand in the tank. I personally prefer by hand.

Cowling is no doubt a 1981. Top of number 2 cyl will be a plug with numbers.

[930turbo]

I've had inline 6 and V4, I'd say they're both excellent. The 100 cu in outboard era was the best.

[JWTjr.]

No oil injection. Economix (seperate oil tank with "computer" and lines to engine) was an option in the 81 accessory catalog, but it's fairly rare.

The lower unit looks narrow for some reason to me. Does this lower unit take the standard 4 inch barrel 15 spline prop? My Inline merc props should work on it as long as spline depth is taken care of correct? Last thing I can think of is what is the gear ratio? 2-1?

Thanks again.

The shaft and splines are different than your inline. The spline is a 13-tooth design and requires a different propeller hub. Max diameter is 14". Gear ratio is 2:1.

Thanks John. I see they are listed at roughly 350 lbs. That heavier that I expected. The L6 Merc is in the 300 range.

Thats too bad about the prop shaft. Ive actually got some OMC second effort 15 spline props that I use on my L6's from time to time. I assumed they were the same.

Good info!

[milkdud]

Well I must have read the specs from a different 140. Im seeing 306 to 315 is the listed weight.

Mine is a '79 and it doesn't look like that. And you look up the year by model number, not serial number.

I paid $1300 for mine without a control box and it was not as clean as the one pictured. Mine is a '78.

I paid $400 for mine with out a control box and it is cleaner than the one pictured above!!! Never a bolt removed on the power head. Low, low time with hardly any paint worn of the skeg. I had no idea it was worth 2500.

IMO the early crossflow V4s and V6s are some of the smoothest reliable motors every built!

In my opinion it had one of the best color/decal schemes.

Ditto. We had one as a kid. I remember going out there sitting in the boat and playing with the trim so much that it ran the battery down. Oh well, being 9 years old will do that.

lb per lb, one of OMC's best ever. I had a 135 version of the same motor on a 16' 1969 Checkmate and it was one of the best balanced, best handling packages I've ever owned. Even w/the low compression head gaskets it still ran 60 and would jerk me up on a slalom ski.
BTW, great response JT.
