Sportwin 9.5

[diverdog]

I just bought a Sportwin 9.5. I bought it from a private seller but met him at the boat shop where it was just gone over. The guy said he put a new impeller, seals, lower unit oil, points, and condensers. When I went to pick it up they said they just realized that the exhaust was leaking and told me to come back in a couple days and it would be fixed. I went back and it ran great. He put the cover on and ran it for about five minutes to show it was fixed. It seems to be running perfect but I have a question about the pee hole. It is spraying water out, but not in a stream, there is just a hole in the case without a rubber hose. It seems like a lot of water but it is just splattered, if that makes sense. On my 2.5 hp, it has a hose and there is a steady stream that comes from it. Is this normal on this sportwin? How do I check the impeller. Are there any other things I should check? What size prop should I buy for a replacement, diameter & pitch? I fish a small river with strong rapids. Where can I get sheer pins and what size would I need? Also could you tell me the proper year. I searched a couple sights and I'm getting conflicting info. One says it's a 72 one says its a 73. the model # is 9223M, and the serial is
J01456. Also where can I get the right manual. I see some that run for a bunch of years together but they stop at 72, which one will I need. Sorry for the long post, and dumb questions but I am an outboard newbie. Thank you for any help you can give.

Re: Sportwin 9.5

So many questions. First of all congratulations on the new motor. They do run well and so far I've had no trouble getting any part I've needed. You didn't mention new coils but maybe they were already changed out. If they show signs of craciking your best to change them. Ya the pee hole on the 9.5 is different. It should be called an A_ _ Hole. You say no rubber hose but if you look there is a sort of coregated rubber hose but it more like 1/2 or 3/4 inch round. Sounds like it is working as designed. I just purchased drive pins from my OMC dealer. You see lots of props on eBay for 9.5's. Mine is a #9322B and it is a 1973. You will be able to find a manual on eBay. Get one from 68 to 72 and you can use it for your motor. For parts diagrams (and you should be able to find your model number/year here as well check this link. Best of luck. Rick.

Re: Sportwin 9.5

Yes, they blow water out the exhaust relief hole along with some exhaust. Not like a water hose stream. Your motor is a 1972.

EDIT: The model number indicates that it is a long shaft model. But it may have been converted to short (?)

Re: Sportwin 9.5

1972 here are the correct manuls for that motor http://www.outboardbooks.com/index.cfm?fuseaction=models.main&year=1972&ID=108401

there were some changes on the 1972 models, from the previous years.

Re: Sportwin 9.5

Thanks for the quick replies. I found that it is a 72 from evinrudes parts manual site. You have put my mind at ease about the a__ hole. I was really worried about it yestarday, and it kind of hampered my day cause I wouldnt run it for more than a couple of minutes. It must be good luck cause I was nailing the rainbows yestarday. What a blast for my first trip out. I just got a 14' jon, and put a floor and carpet in it, along with some new seats. I am loving it. Again thank you for the quick answers and I'm sure you'll be hearing a lot from me from now on.

While I'm at it, I wasnt able to get on plane yestarday. I tried every position on the bracket with no results. It was bringing the front way up. I put the dog up there but her 75lbs didnt help. I am thinking about getting another battery and mounting them in the front to help. Do you think a hydrofoil would get me there? It felt like I was close. Also I am thinking of making a prop protector cause I run in a shallow rocky river. How bad do these affect performance? I'm not worried if it does cause I'd rather be able to run in shallow water than ride on plane all day. I cant go fast anyway due to kayakers, and canoers.

Re: Sportwin 9.5

well you will throw less wake on the other boats if on plane. i think i would try a mini foil. and get a long fuel line, put the tank and anything else you can forward.

Re: Sportwin 9.5

I agree with tashasdaddy. just be careful no to overload the bow or you'll be plowing and never come up to plane.

Does the engine seem to be running at a high RPM? I have a 14 foot modified Vee and my 9.5 brings it up on plane in the snap of your fingers. You mentioned that the dealer said it had an exhaust leak when you went to pick it up? If you have an exhaust leak it may be trying to burn exhaust gas instead of oxygen. Try running it on your boat (can't get enough of a load on it in the tank) with the hood off and see if it runs any stronger. If it don't, thats not the problem.

Re: Sportwin 9.5

I will try that lightfoot. The guy showed me the old rubber piece that he had to replace so I don't think it is pulling any exhaust in.

I have a new problem now. It ran great yestarday and now today it is running terrible. It seems like it is missing, or maybe overloading with fuel. When I first fired it up it seemed a little off as compared to yestarday. It sounded a little better at idle but as I would rev it up it would get worse, and worse. At first I just thought the added weight from my buddy being in the front was causing more drag, but I had him get out and still had the problem. One time for about a minute it revved good but when at WOT, it started to sound funny again and slowed down. You can feel the motor, it's hard to describe maybe choppy. I really think it is missing. I would say it's either missing, getting too much fuel, not enough fuel, not getting spark. Do you guys know of any common problems that would cause this? I read on one post that the motor runs good on 1 cylinder, and I wouldnt describe it as good at all. It is probably only going about half speed as compared to yestarday, and it definately is not revving to where it should. Where should I start checking and how do I check it?

Another question is that it has holes in the back where the handle is to lift it up and there is foam on the inside of the cowl but non where the holes are. I would think the foam should be covering the hole to act as an air filter but it is cut away, so basically the motor has no air filter. Is this common on outboards being there wouldnt be any dust where your running it? Or did someone cut it out to jury rig another problem the motor may have. Thanks for any help you can give. And I'm a total out board newb so if you could explain things in outboard idiot terms so I can understand them I would appreciate it.

Re: Sportwin 9.5

No air filter is required due to the clean ambient air your using the boat in. I asked you if you had new coils but you've never said one way or the other. You could be running on one cylinder. When it's running rough pull a plug wire. If it slows down that means that plug was firing. Re-attach it and pull the other. If the engine slow down it means it was firing. If pulling either causes it to quit then the other plug is not firing. If it seams like your going half speed it could be that your one on cylinder. Rick.

Re: Sportwin 9.5

Thanks Rick! I'm not sure if he put coils in it or not. I'm gonna call him today and ask. The machanic is 2 hrs. away so I am hoping I can fix it myself, or else I would take it back and complain or try and get a discount on the fix. The bad thing is that I didnt by it off the boat shop guy and I hate to bug him over a motor that his buddy sold. I'm gonna try and find a barrel today so that I can start trying the things you guys are telling me. I have seen water muffs at WallyWorld, but my water intake is tight against the cavitation plate and I dont think it would get a good seal to pull enough water in.

Any other ideas fellas?

 

[Rick.]

Re: Sportwin 9.5

I prefer a barrel to muffs any day. For small motors anyway. You really need to get an OMC repair manual for yoursilf. There are so many things covered in it that are important and will get you more informed about your motor. Procedures that are simple yet not available here due to the tremendous amount of typing that would be necessary. Don't over rev. your motor in a barell. I use a large rubber maid garbage can and it works well. Make certain to have the water at least 1/2 way up the leg. At the top of this forum there is a link called "Top Secret File". Have a look through there and you will see some things you could be checking. Rick.

Re: Sportwin 9.5

Your primary water intake is at the cylindrical screen just above the propeller. The intake that is just above the anti-ventilation plate is a secondary inlet for running in reverse.

Check your flywheel nut, it sounds as though you may have a sheared key because someone didn't torque the nut to specification (40-45 foot pounds) .

Re: Sportwin 9.5

Well, I couldnt just sit around and wait til Monday to get it fixed. I pulled the plugs and they were brown but wet. I sanded em and wiped em down and put em back in, still running bad. So I took them out and cleaned em again this time I started playing with the rich/lean knob on the front face of the cowl. The knob was turned all the way to lean. I turned it six turns toward rich, and tried it again. This time it fired right up and I was able to get it to idle smoothly. I ran it for a few minutes reving it up and holding it. It seems to be running good now.

I have taken some pics and videos and have a few more questions. One in these pics there are holes drilled, I cant tell if they are factory or not. The ones in the back are the same level as the exhaust and water hole so I am thinking when running the motor that water will be getting inside the cowl. Should I plug these up??

Ones on front:

Did they do this factory or did they drill these ones inside the handle for more air flow:

See all the oil on the surface? I know there will be some, but should there be that much?

If you watch this video there is water coming down out where I am pointing. There are no little holes that I can see so I dont think it should be doing this. I think it is coming from somewhere up inside. It is definately coming out with some pressure and not just dripping down. Will this hurt anything if I let it go or do I have to find out where it's coming from and seal it? Could I use some J B Weld if I have to seal it?

This is what I fooled with turning back and forth and finally got it running good.

Is this just a fine tuning? Can I hurt the motor by adjusting this too much and not knowing it? It says slow speed so I am afraid it will still run bad at WOT unless I had a couple of problems. I am thinking that by the slow speed adjustment being wrong, I carboned up the plugs then it started running bad at all speeds. Hopefully I can get it out on the river b4 Monday and see how it does. If the water in the video is something bad I will probably still take it back to the shop and have him fix that. Thanks for all you guys help. I'm sure I'm driving some of you crazy, cause I'm driving myself crazy with all of this.

Re: Sportwin 9.5

Glad to your your running again. Six turns out sounds like a bit rich to me. Did you go straight to six or did you get there turning a little bit at a time? You could try turning it in in 1/4 turn increments waiting a little at each stop. Once you notice it start to sneeze, (like a miss) open it another 1/4 and you should be fine at that position. Mine ended up somewhere between 2 and 3. I wish I could remember. Not sure where that water is coming from but it looks like the general area of the shift rod? Maybe, I'm not sure. The main thing is are you getting good cooling? You should be able to place your hand at the top of the head for a three count. I don't know what the holes are for. Perhaps it was to better ventilate the cowl when the exhaust was leaking. I know I've looked at mine and wondered where it gets it's combustion air from. There certainly isn't many square inches of open space to the outside. If you cleaned the high speed orifice well you won't have any problems. It is not interconnected with the slow speed and it is fixed (non adjustable). Don't rev. it too fast in the barrel. It isn't good for your motor and really unnecessary as there are no adjustments to be made when revving it fast. Go fast in the lake where the motor is using it's HP to move the load of the boat. Good luck on the water, keep an eye on the temperature. Rick.
