Now back to Evinrudes. I have heard that the reeds can deteriorate over time. But sometimes they can build up with carbon not allowing them to seal correctly. Regardless, I believe that the reed is on track with the troubleshooting.


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

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.

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. :)

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.

PS
I apologize for the people who garbaged up your thread. Usually they
can be a little more polite when there is a serious boat conversation
going on.

Guys cut it out. We have plenty of flame threads you can use.



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.

BTW 54 Mercury for me. Lock nut from a carburetor bolt. The machine
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.

I drove the Mercury until I went into the CG (only a few months) then
I gave it to the guy who helped me fix it.

Wasn't Johnny also wondering about spraying WD-40 into his outboard to
"winterize" it?
That was a question my Netherland's friend had.

How are your owls? Red barn need any paint yet? Income taxes paid yet? How about all
those soldiers you found that had been left behind by their units? What organization
was that again?

See, Harry, I don't have a problem addressing your questions. Wonder why you have
