On the flip side, I went through 3 V4 OMC motors and they were bullet proof. I ran them in horrible conditions, mud,grass,logs, and blew one head gasket, one stator, and a fuel pump in about 10 yrs of work. Great motors. I have an old V-4 Johnson 150HP A Johnson mechanic told me it was the best motor that they ever built. He told me never get rid of it No such animal ever existed. Johnnyrude V-4s were 88-140 hp. All 150 hp were 6 cylinder. Not tryin to be the Tarp of outboards, just sayin.

Omc (Johnson/Evinrude) had 85, 115 and 135 the later they changed them to 90, 120? and 140. All were v-4s.

The 90-140's came with the introduction of the VRO oil injection. The 'Rude 88 special was introduced at the same time as a non-VRO motor because they believed people wouldn't accept the idea of oil injection. On the 90 and 115 that I owned, I removed the oil injection after they were out of warranty.

I hope it is still working properly

The early models were cross flows. Then came the loopers which were much better. More power and better economy.

Illinoisfisherman, you are outboard motor poor! Needing the key for one, needing to fire-up the 225 and now a 140 that hasn't run in 10 yrs. Sell them all, and get a single good running motor and use it. The worse thing you can do to an outboard is let it sit.

You are right about the 225 Yamaha, it was a dog. The mid section was notorious for corrosion. The problem you would have today with the E-rudes would be finding parts and tech support. All companies make good and bad motors, unfortunately we sometimes don't know the difference until we have bought them. Agreed, but the forums are full of yamaha fan boys that act like theirs don't even need gas, and will run for 9000 hours or so before even needing a tune up. All of the motors being built now are dang good motors. All of them break, also. And if I still had that boat with the 225 2/s carbureted Rudes on it I would have no problem getting parts. The weren't Etecs, and they weren't Fichts (probably some of the crappist motors ever made). No fuel injection Just carberators. I think they were called loop charged motors. I know a number of people who still run those, and they say parts are easily found. Not so much with the Etecs.

Another thing that mechanic told me to do was get a can of Seafoam. Stick the foot in a barrel of water, bring the idle up to 1200 rpm or so and spray the Seafoam into each carb. It'll belch, blow all kind of crap out the exhaust, try to stall, etc. But it'll help clean all that built up carbon out. And it did. Ran a can of Seafoam in the first couple of tanks also. That's one of the best things you can do to a carbed 2/s motor.

There used to be a poster on THT and the old forum that went by "Dink". He was an OB mech and he really pushed using Seafoam for cleaning out engines. I believe one of his methods was a quart of Seafoam to a gallon of gas. Crank it on this and let it stall the motor. Let it sit for 30 minutes and crank it on normal fuel (with ob oil). It will blow all kind carbon out the exhaust. Keep repeating until you get a normal looking exhaust. Before I tried to start the motor, I would do as previously recommended, use the Marvel Mystery oil liberally in the cylinders, leave the plugs out and rotate several times by hand and let sit. Good luck. He was a top dog surveyor also. Lived it the NE I believe.

Good luck. I think he passed unfortunately. But he knew his shit. Yup, Dunk not Dink. And he was a surveyor. The post on FS was "Decarb that Outboard". And he did pass away a few years ago.

I used this stuff on my 1995 Merc 200's. I would go out in Biscayne bay and spray the carbs and run the engines at 5K RPM. The smoke that came out was crazy but the engines performed better afterwards.
