NEWB Needs advice: 1961 Evinrude Sportwin 10hp Model 10022

Hey fellas. I just picked up a 1961 Evinrude Sportwin 10hp from my uncle. He said it hasnt been started in about 3 years. From what I can tell, the motor is free and the spark plugs and wires look brand new. Can any of you motorheads give me some advice as to what preventative maintenance to perform before trying to start this motor?

From what I found online, I should run a 24:1 gasil ratio. Correct?

Thanks for the help!

YOU CAN AND SHOULD RUN IT A BIT RICHER WITH THE OLDER MOTOR TO PUT A LIL EXTRA LUBE IN THE CYLINDERS. EVEN NEW MOTORS I BELEIVE SHOULD BE A LIL RICHER, IT WILL HELP EXTEND ITS LIFE.

DRAIN THE LOWER UNIT AND CHECK FOR WATER AND IF PRESENT REPLACE PROP SHAFT SEAL AND THE SKEG SEAL AND FILL IT BACK UP, OTHER THAN THAT FIRE IT UP AND SEE HOW IT RUNS. I GAVE MY BUDDY A 61 5.5 FISHERMAN THAT I WISH I WOULD HAVE KEPT BUT HE NEEDED A MOTOR. THEIR COOL MOTORS AND PARTS ARE EASY TO FIND AND THEY ARE EASY TO WORK ON WITH JUST BASIC MECHANICAL KNOWLEDGE...

Thanks, Shawn!

So mix more oil with the gasoline?

If possible run the engine on ethanol free gasoline.
Your tune up should include an ignition tune up, points cleaning and set at a loose .020. Check ground wires and condensor wires plus loosen ground screws and clean connections and re tighten. Spark plug wires should be checked both at the coil end and the plug end. Check for cracks in the wire, corrosion at the ends. Check coils for cracking and replace as necessary. Carb should be checked and cleaned as necessary.
Probably the most important service point is to install a new impeller at the very least or a complete water pump if the cup or lower plate has any grooving in it.
Monitor the gearcase lube for the first few trips and reseal the gearcase at the first sign of water if you dont feel like resealing at the time the water pump is serviced. New spark plugs arent really that necessary.
By all means run at 24:1 mixture. Much cheaper than replacing a powerhead due to lack of lubrication.

yeah just a little...

Update:

I decided to take a look at everything and found that the coils are completely dry rotted and the lower unit is leaking oil somewhere.

Is this motor, being that it is from 1961, worth my time and money to get running? I dont want to spend a bunch of money and not know if its going to last or not. Anyways...thanks for all of your help!

I would say "yes," but wait for the pros.

At the moment, my best and most reliable motor is a 1959 Evinrude 10. Could be just a gasket on the lower unit, and the coils are a simple fix.

Best wishes.

Looked into the coils. Looks like they are 26$ each. Anyone know how to remove the flywheel? I got the nut off but its not budging. Thanks!

Flywheel takes a puller to get it off. There are three screw holes around the crank that the puller screws go into.
Yes, the engine will last if you go through the service steps laid out for you. Shortcut them and the answer is no!
Those engines are built like tanks and have great torque and power for their size. If you take care of it and run and maintain it properly you can hand it down to your grandkids no problem.

Can you point me in the right direction as to what flywheel puller to use? Thanks!

Just go to Napa or wherever you want to buy tools and buy a puller with three concentric slots around the center. Find out what thread the flywheel is on that engine and buy the correct bolts and several flat washers for it. Make sure that all the bolts are at the same height when you pull the flywheel. Put alot of tension on the center bolt and smack it with a hammer and it should pop right off. Make sure the tapers are extremely clean when reinstalling and do not over torque. If you do not know what you are getting into then buy a manual for it and go through it first.

10 4. Thanks, Pappy.

Brandon,

Good old engine you have there, I have one myself, it is the engine I use most on my Scott Canoe Hudson Bay freighter, it will push it along at about 14 mph. Follow the link below it will give you a lot of good reading and pointers as to tuning her up to run right.

That really helps, Stacker! Thanks a bunch

Well....thanks for all of your advice but I have decided to move on and purchase a newer outboard in running condition. I just dont have the experience with outboards this old.

Tell ya what...I went back and forth all day yesterday on wether or not to restore this motor or not. I finally made up my mind and ordered new coils, condensers, points and a carb kit. I also went to Napa (thanks to Pappy) and bought a flywheel puller. I removed the flywheel with no issues and took off the carb. I cant wait for these parts to arrive!!

Good for you, keep us posted as to how things are progressing. I would do a compression test on the engine before I got to involved just to make sure I had a good base to start with.

For some silly reason, that makes me happy.

None of my business, but was disappointed when you said you were going to let it go.

Can be one helluvan engine.


Best wishes.

Haha. Im glad that makes you happy I am glad I decided to keep going. So far I have around 100$ invested in the motor with the parts I ordered last week.

I'm sure once I start rebuilding, I will have plenty of questions!

Update: Carb kit arrives this afternoon

Question: When I took the carb off of the motor, I noticed that inside the bowl(which is glass), the threaded disc that holds the float? up was loose. (I wish I had a picture of it at the moment but dont). The disc is threaded which screws onto the nozzle? Should this be tight up against the float?

Do I have this correct? If need be I will post pictures later today. Thanks!
