Classic '71 40HP Evinrude Troubleshooting Question
 

Hi All,

I have a 1971 40 HP Evinrude (model #40152B). I bought it used a few
years ago, and its actually been a great runner even though I admittedly
abuse it maintenance-wise. Damn thing starts up quicker and more
reliably than my '85 Merc...

Anyway, this year, its started "spitting" and "coughing" at low RPM's.
When throttled maybe 15% past idle, it sounds great. If the gas were
bad or the oil mixture not right, the RPM's would not matter, correct?

I've changed the plugs and poured some seafoam into the tank and ran
hard on the lake for a good afternoon, but neither seemed to help the issue.

Any suggestions on what to do next?

Thanks,

Ryan

For the record, the sound is similar to a sneeze, actually. If I have
the cover off the motor, I can actually feel air blowing back out of the
carb

Thanks

Dirty carbs, low speed carb needle adjustment?

Bad reed valves.

Forgot to mention why I mentioned the reed valves. I had a 70hp, 2
stroke Evinrude of about the same vintage. Exhibited exactly the same
symptoms ... ran fine at higher RPM but at idle it would "sneeze", miss
and stall. The problem was the reed valves that are the 2 stroke
versions of a 4 stroke's input and exhaust valves.

Dirty carbs, low speed carb needle adjustment?

The carb IS due to be cleaned, for sure. That's a project for when I
have time to learn on the fly. I was hoping that if it was carb problem
(that just developed) the SeaFoam would clear it up.

As for the needle, adjusting the needle doesn't effect the problem,
except as it relates to increasing the idle speed.

That doesn't sound like fun... It looks like I would have to pull the
carb to MAYBE see them, and probably the reed block. Did you replace
them yourself, or find somebody to do it?

Maybe I should consider selling her to somebody else as a parts motor. :)

I had a pro fix it. I am not a mechanic by any means.
The "sneeze" is really backfiring through the carb because the reed
valves are worn and don't seal at low rpm.

Your problem could be something else obviously but worn reed valves will
cause exactly the symptoms you have.

The one I had ran great after they were replaced. A lot cheaper than a
new motor.

I would try the carbs, it can't hurt but I think Richard is right.
Lots of cranky 2 stroke problems get back to the reed valves.
I did therm on my 75 Merc. After you get all of the carb linkage
loose, it is not that many bolts to get the manifold off and get to
the reed block. I usually get a few plastic bowls and keep the parts
from each stage of disassembly in another bucket. That helps when you
are putting stuff back together. Taking pictures is good too..

Yeah, I saw that while I was looking around earlier. My beast of an
ancient motor looks a lot different... but I assume the basics are the
same? Pull the (single) carb, and that should get me access to pull the
plate containing the valves?

Off to the Evinrude site to try to get a part number and source it for
a 45 year old motor. :)

When I had the old 2 stroke, outboardparts.com was good to me.
Mr Stibler was pretty good about helping me get the right part.

Ain't that the truth? She was my first boat, and owning it has taught
me a lot... Replaced the starter and solenoid, replaced the

When I upgraded from the '71 SeaSprite to the '85 Phantom, I wasn't
afraid to dig into replacing the rack steering. Saved me a bundle on
paying more for a ready-to-go boat. lol

Agreed. If it's blowing back thru the carbs there is definitely an
issue with the reeds.

But but KKKrause says clean the carb. He should know. He has the blood
of an Evinrude dealer coursing through his veins. :-)

No problems here. As soon as you ask a question I considering worth

I did have my doubts when I saw the majority of the threads in this
group... But so far, the folks actually responding to my questions have
been very helpful. :)

I'm going to put the old girl in the water and spray some seafoam
directly into the carb while she's running. I know its a 45 year old
motor and the more I research, the more likely it is that the reeds have
deteriorated, but a can of SeaFoam is pretty cheap and easy to try
before I start dismantling the engine.

The rich folk who live on the lake are gonna love my white smoke. lol

Classic '71 40HP Evinrude Troubleshooting Question
 

Good luck with it Ryan. Old Evinrudes are tough engines. And the seafoam can't hurt. And if it does need reeds somebody has them.

But as you can imagine new parts are getting tougher to find. But they can be had.

Some time you can get the reeds working better just by running it hard
for a few trips out but you still should plan on doing it. It might be
a good winter project if you are in a winter place. I nursed my old 2
stroke 75 along for quite a while before I finally bit the bullet. I
still ended up selling it and buying a 4 stroke but it was running
well enough to get a grand for it.

I would start with Don at outboardparts.com. He knows a lot about
these old motors and had a pretty good supply of parts every time I
have looked for something..

Yep, in Wisconsin.

I saw on a thread somewhere else that the best way to attempt
"cleaning" the reeds is to get the motor up to operating temp, spray a
bunch of SeaFoam in the carb while running at 2 or 3k RPMs, then stop
the engine and let it sit for 15-20 minutes, then start her up and run
her hard until the white smoke clears out.

Honestly, I don't want to stick too much money into it since I have
the newer boat with the Merc, but I'm willing to do some basic stuff to
it as a learning exercise and as a way to bump up the sale price.

Not to mention the stubborn in me that hates not knowing how to fix
something. :)

Classic '71 40HP Evinrude Troubleshooting Question
 

Ryan, at those RPMs just make sure you don't dump too much in the carbs to lock it up. Those motors are rock crushing tough but you could crack a head and or hydrolic and bend a rod. Fog only what it will take in short bursts.

Yup, I figured that was what you meant when you said you were going to
hit it with seafoam.

I hear you. If you can swing it, buying a new 4 stroke is really the
way to go. They just run and run. It is really nice to be coming into
a crowded restaurant dock, with a plan of how you are going to do this
thing and knowing it is not going to sneeze at the worst possible
time.

The other thing to consider (and I am sure you've read about it) is
that the original reeds are likely to be stainless steel. They fatigue
over time and eventually some pieces can break off and enter a cylinder,
causing a lot of damage. The replacement reeds will likely be carbon
fiber.

Many years ago I accidentally dropped a small lock washer into the
carburetor of a Fiat 850 I had. It was dark and I had removed the air
filter housing for some reason. When I went to put it back on I heard a
"tink ... tink", not realizing that there was a small lock washer under
the wing nut. Destroyed the aluminum head in the engine.

Two strokes are a little more tolerant of trash than a 4 stroke but it
is still a concern.

shop could fix the head but it was never really right after that.

Same here. Needed a valve job afterwards and had to have the head
planned. I was hoping that would produce a little more compression and
maybe result in a bit more horsepower but it really didn't make any
difference. Just an expensive fix at a time when I could least afford it.
