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 numberQuote:

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.
I've had inline 6 and V4, I'd say they're both excellent. The 100 cu in outboard era was the best.
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.
C
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.
John
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!
C
Well I must have read the specs from a different 140. Im seeing 306 to 315 is the listed weight.
C
Mine is a '79 and it doesn't look like that. ;) And you look up the year by model number, not serial number.Quote:

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.
I should clarify my purchase price, I paid $340 and promptly spent $960 on bits & pieces and asthetics. That was prior to powerhead #2 with all the mods. I did the same thing with the hull, immediately spent way more on repairs and upgrades than original purchase price. I'm pretty sure it's not the wisest investment outside of making me happy. :DQuote:

Im pretty sure Evinrude had a photo in there sales literature and they had that motor on the back of an Allison.
I drooled over that photo for years:)
They did...they ran several ads as well as brochure shots (in the '81 and '82 brochures) of the 140 on a GT-20. Powerboat Magazine tested the GT-20 in their 1981 reviews, with a 1981 115 Evinrude. It ran 54 mph with a 24" Chopper and they gave it rave reviews. This was at the time of the 1980-81 "energy crisis" and many of the manufacturers supplied boats that were downsized in size and/or power to go along with the theme. HydroStream sent a Vandal with 75 Evinrude (1980). It ran about 45.Quote:

Up here in the Northeast, a crossflow of any vintage worth buying ('77-mid-90s) goes for about $300-400 if damaged (scuffed pistons, cylinders, etc) and from $800-$2500 if not damaged and of course depending on condition. I sell rebuilt crossflows 90/115/140 hp for $2995 (includes propeller, but controls/VRO/installation, etc. extra) and I sell every one I can build. It's a bargain compared to a new engine.
John
Thanks for sharing that John. Back in 1982 I had no idea that was a 20 footer.
I had seen a few Allisons back then. I had probably only seen a couple of Hydrostreams in person at that time (on Dale Hollow). I still have that sales lit in the garage somewhere.
I think I was running a 16ft Baja "tri hull" bowrider with a 1981 115 Rude. That was my first brand new rig, the second was an 18ft YT with a 175 crossflow in 87.
V6 / 15 spline can be installed in this lower unit w/ minimal mods.
Greatly increasing prop selection.
I do it the hard way. $62 rehub on every prop I tryQuote:

All the V6s had that color scheme in 1981. They offered a 150, 175, 200 and 235. The 235 was 160.3ci, the others 149.4. The 149ci 200 was th original production V6, first year 1976.
John
Thanks John for the info! I had heard that while the 1981 99ci 140's were very stout motors, the 1981 V6 200s were somewhat weak, perhaps making less than 200hp. Any truth to that?Quote:

Thanks, very interesting. I had heard that the 1981 2.4L V6 200 "Sport" actually were a touch weak and made about 185hp. My confusion might be around the date that the manufacturers switched from flywheel ratings to propshaft HP ratings which was "I think" 1984?
Scribed. Gary
I also think that the 185 pretty quickly became a 175 model in 1985 so I wonder if the 150c.i. powerhead that you dyno'd making 200hp in 1977 perhaps lost some power by 1981 for some reason?Quote:

Year 1977 99.6 cu. Great motor. Had one in 1977 on a Hydrostream Viper. It came standard with Tilt&Trim. And a swept back lower unit.
GOT ONE "IN PARTS" IN MY SHED .....RAN ON MY VIPER 68 MPH WITH A KILLER MACH OVERHUB 24" @ 6800 RPM
THEN I PUT IT ON A SMALL 16' SEABOLD TUNNEL AND RAN THE CRAP OUT OF IT ....NO TACH.... BUT IT WAS TURNIN MORE THAN WHEN IT WAS ON THE VIPER AND BROKE A RING OFF.....AND STILL RAN "ON 3CYL" 60MPH.
RING SHARDS WENT OUT THE EXHAUST AND KEPT ON RUNNIN.
I HAVE BEEN PLANNIN ON REBUILD BUT JUST LOST INTEREST IN THE OLD CROSSFLOW STUFF.:nonod:
I HAVE ALL THE PARTS, THE PROP, BAKER MARINE WINGPLATES, NYDAHL STERRING, ETC...IF ANYONE IS INTERESTED PM ME .
