Just bought my first outboard today. Not sure of the year. Was told 1975. Its an Evinrude Sportwin 9 1/2
Dumb move on my part. I got no manuals with it. Came home knew it used oil gas mix. Was told 50 to 1 mix. I put 2 gals gas in the tank on the way home. Without thinking I grab a can of 2cycle oil and add it to the tank. Standing there thinking I knew I just screwed up. Stupid question time. Do I have to get rid of that gas or can I just mix another oil with it. I know the answer I think just need it confirmed.
What oil should I use and is 50 to 1 mix correct. thanks for any help

If it really is a 1975 9.5hp, it is a 50:1 mix.
TC-W3 two-cycle outboard motor oil is used.

Re: Dumb question time... Evinrude Sportwin

The last year of the 9.5hp was '73. I think the 9.9 started in '74.
Either way, I hope you got a nice motor and if you need any help getting it running perfectly in case it does not, you're in the right place.

Re: Dumb question time... Evinrude Sportwin

I had a sport twin yrs ago. Wish i had kept it! It was a awsome engine It ran lower rpm's than the later 9.9's but it was a very good engine for me and for over 12 yrs never had a issue with it. 50:1 is im fairly certain is the correct mixture as i used it for the entire time i had mine.

Re: Dumb question time... Evinrude Sportwin

Thanks for the help. I do have the model# and serial# did a search and came up with nothing. I would like to get a manual for it. I would like to get spare parts to keep on the boat, (prop, sheer pin) things like that for emergency repair if needed. Plus I'd like to change the lube in the lower unit. So hopefully I can figure this out.

Re: Dumb question time... Evinrude Sportwin

What is the model number?

Model# 9022C I just found it. It's 1970. I guess I got suckered. If he wasn't truthfull about the year I would almost bet this engine has other issues that wasn't given. Well it did start right up looks clean and sounds good. I'll keep my fingers crossed. I may just have the carb rebuiltt and replace the water pump Thanks for the help

Re: Dumb question time... Evinrude Sportwin

Well after getting all the stupid out of me I went over the engine the best I could without a manual. There are a couple things I did notice.
1) The carb and area around the carb looks wet. Not dripping wet but it is wet you can wipe it clean. Is that an indication that the carb needs rebuilt? I think I could do the rebuiled. The adjustments to the carb after replacing might be a challenge.

2) I can't find an in-line fuel filter anywhere. Is this normal on this model? If there should be one where should it be located?

3) The pull rope looks to be fairly new. The handle has electrical tape around the end the rope goes through. Should this be a concern?

4) The pad attached to the under side of the hood looks to be fairly dirty. Can this pad be replaced? I did give it a slight pull it seems to be glued in place.

5) Another thing I noticed is it looks as if the parts all have numbers on them. Are these numbers the parts number?


I have searched and read the sticky threads to get some kind of ideal at what I have and what problems I might run into. I pulled the plugs they look good and clean. There doesn't seem to be an over amount of play when I grab the fly wheel and tried moving it. Maybe 1/8 if not less of play in it. Everthing looks to be in place and operational. The only thing missing is the adjustment knob on the front of the engine. I do think I can find one of those.

After going over the engine I think I might have a winner here. Not to say I wont have some kind of problem. I'll take those on as they come. Thanks for the help

If anyone has a few tricks or tips to keep this thing running like a champ feel free. again thanks

1) Follow the line from the tank hose connector on the side of the engine, and you will find the fuel pump which has a plastic housing held on by a stainless steel screw. It holds the filter screen.

2) Those handles have a tendency to split....where the tape has been placed. If the tape offends you, new handles are anywhere from $5- for a generic, to $15- + for the OEM. It will work fine with the tape. :D


Here you will find a parts list for your engine:

You can handle it. An outboard carb is simple to rebuild. Read the "top secret files" thread at the top of this forum and there's an excellent thread by Joe Reeves on how to adjust your carb.

2) I can't find an in-line fuel filter anywhere. Is this normal on this model? If there should be one where should it be located? There's no reason you can't add an inline filter if you want to.

3) The pull rope looks to be fairly new. The handle has electrical tape around the end the rope goes through. Should this be a concern?

4) The pad attached to the under side of the hood looks to be fairly dirty. Can this pad be replaced? I did give it a slight pull it seems to be glued in place. I'd leave it alone. The insulation is NLA.

5) Another thing I noticed is it looks as if the parts all have numbers on them. Are these numbers the parts number?

As long as you keep it pumping water good, and keep good clean fuel with TCWIII at 50:1 in it with clean fuel lines, it may well outlast you. THe only other things that you should have problems with that might be hard to solve are exhaust seals and motor mounts. Clutch dogs/gears, lower unit seals, and ignition systems are common problems with used motors but shouldn't be a problem to fix on your motor. Used parts or NOS stuff from fleabay are often available for reasonable prices.
DOn't worry that it's a few years older than you were told. 5 years is nothing on an OMC outboard. IT was probably not purposeful that you were told the wrong year. I've seen a lot of older outboards for sale which the seller didn't even have labeled in the right decade......
Good luck with it.

Re: Dumb question time... Evinrude Sportwin

Heres what it looks like

In pic 4 this looks to be an adjustment for the angle of the motor while running. What would be the correct setting for this?

Re: Dumb question time... Evinrude Sportwin

Few more pics. Saturday will be the first chance to see how it runs on the boat. Looking forward to it. The back side of the lake has always caught my eye on the map. Being only with trolling motor I never took the chance going that far. can't wait to fish that area.

Looks like that control knob is going to be harder to find than I thought.

Thanks for all the help

Set your motor so that the antiventilation plate (the flat fin sticking out over the prop) is parallel to the bottom of your boat. If the motor is tilted too far up, the boat will porpoise. If it's too far down, the bow of the boat will plow in the water.

Thanks for all the help I really appreciate it. The links you folks have provided, parts look to be no problem. I'll keep an update as I do the work. I'm sure I'll need some advice along the way. again thanks

Re: Dumb question time... Evinrude Sportwin

Well had it out on the lake yesterday and today. Took a few pulls to get the whole time it ran.it started yesterday and a few more than a few to start today. Both days it started on the first pull the rest of the day. Not sure how fast it should push the boat. It ran fine just not sure if it had all the power it should. (if that makes any since) The reason I say this the bow never really lowered while at full power. At times on low idle it would die. I turned the low idle adjustment knob by the handle but it never made any change in sound or idle. Shifted in to reverse and forward very easy and ran in both directions. It pumped water just fine had a steady stream.

Re: Dumb question time... Evinrude Sportwin

In a 12 foot aluminum I often put a few large stones in the bow just to give it some weight up front and bring the bow down a bit. As far as top speed goes you may need to check your RPM at WOT. The 9.5's seem a lot slower than a 9.9 to me. Out of the hole and top end but the 9.5's have a look all their own. Best of luck. Rick.

Re: Dumb question time... Evinrude Sportwin

Been going over the motor just inspecting things. Pulled the plugs looked clean. The plugs that are in it are not the plugs that the book calls for (J4C). I'm sure they are compaitiable for the motor. I noticed they are the same plugs used in smaller hp motors (J6C).
The fuel lines look fine but I will be replacing them.
The idle adjustment knob (pic1) by the throttle handle is not working properly. It will adjust in but will not adjust back out. Took a flat tip screw driver applied pressure to the arm (pic2) as I turned the knob and the arm would move back out. Tells me some type of clip could be broken. Explains why I got no change in idle when on the lake.
Want to check the points. Is there something I need to do before pulling the fly wheel ? Line up any markings?
Have a list of parts I will be ordering next week.
