need help with 9.5

[xirocrtx]

I just bought 4 outboards for a sweet price and hope to make a couple good ones from them. 2 are evinrude sportwins 9.5 hp, 1965 and 1967. the other 2 are johnsons, one is a 1971 and the other has the serial plate missing. any help identifying the last one would be great. is there a name for the johnsons? the model number from the one is 9r71r.

first i will check for compression and spark but i still need a gas tank for them. anybody got a spare they want to get rid of?

where could I get a parts list or engine breakdown?

I have a lot of experience with cars but not with small engines, anything important I should know?

Re: newbie to outboards

xirocrtx: Congratulations on the motors. You are right as rain to check the compression before anything else. Spray a little gas/oil mix into the cylinders to lube them up first. They might be very dry from lack of use. Check this link for parts diagrams. I think it starts at 68 but that will work fine for the 9.5's. They didn't change much and were made up to 73. Not sure about the Johnson number but someone will let you know. Your compression should be taken with both plugs removed. Pull the rope until the gauge stops climbing, write down the PSI and then do the other cylinder the same number of pulls and write it down. They should be better than 60 and within 10% of each other. The higher the better. At the top of this forum is a "Top Secret Stuff" file. Have a look in there for guidance about how to bring these babies back to life. Do you think the Johnsons are 9.5's as well? Best of luck. Rick.

Edit: Your title sucks. You should try to edit it and say "need help with 9.5's" so people are more drawn to your posts. Just under Top Secrets there is guidance about how to post effectively.

Re: newbie to outboards

Welcome to iboats.

On the motor missing the tag there should be a welch plug,nickel size, on the power head somewhere with the model and serial number on it.

An engine is an engine but outboards are just enough different that you should start with a manual for those, it will simplify everything and they pay for themselves the first time you use them, they tell you exactly how to test parts to see if they are good/bad and can save you many times what they cost, available here at iboats or on Ebay.

Get an OMC manual, not Clymers, Seloc or anything on cd.

And any gas tank will work, I am using a Yamaha tank on my Evinrude, you just need to match the ends on the gas line, that would be another good Ebay thing.

Re: newbie to outboards

you can get a red plastic tank and the fittings at walmart. you need Johnson/Evinrude Fittings.

Re: need help with 9.5

Thanks for the help, I will look into the omc manual and tank tonight. and might even get to checking the compression this weekend.
I will look around for the plug, Is it a chrome plug on top? thats what I remember seeing on one of the others.
This should hopefully be a fun process and I would like to restore one for myself.

Re: need help with 9.5

I'm just curious how much was the sweet deal. I am currently looking for 9.5 and 9.9's and want to see what others are paying. Thanks

Re: need help with 9.5

You can call me cheap but I don't spend a cent on my (new to me) motors until I have checked compression. Once the compression checks out then I feel a lot better about spending rediculous amonts of money on them. An OMC manual is a number one prioity once I decide it's a keeper. Were these all 9.5's? Rick.

Re: need help with 9.5

mine are all 9.5hp and I got them from one of my neighbors, he said he checked compression on all of them last summer and they all passed. I kinda took his word for it but I will check them for myself now. I thought it was a good deal to pay $150 for all. but now you got me worried. did I pay too much? I am going to wal-mart right now to check on a gas tank and have been looking online at the service manuals. Is there one that covers all of these motors in one book or do I have to buy each year book?

 

[Rick.]

Re: need help with 9.5

No don't worry about being ripped off. You got a heck of a deal IMO. You can order any year OMC 9.5 service manual and use it for all the motors. They didn't make many changes over the years of production. Up here in Canada we pay more than the going rate for parts but for new coils, points, condensers, plugs, gear lube and impellers I would guess your looking at about 200.00 per unit plus your time. IMO, they are worth a good deal more than what your total investment would be. Perhaps you should consider twining them. That would be a site to see. Use a johnson and an evinrude just to help get heads turning. Rick.

Re: need help with 9.5

The only change in the 9.5s (post '64) was in '73 and it has to do with the reed plates. I'd get a '72 or prior manual to cover what you actually have. The later the better, since they had better edits/revisions as the years went by.

The biggest problem on these motors is worn rubber motor mounts. Clamp the motor to a stand, remove the cover and try to shake the powerhead forward and back. It should move some, but not a lot. Find the one with good compression and best motor mounts and start your restoration project there.

Re: need help with 9.5

Cool, thats awesome I just need to buy one manual. I hope these aren't bombed and need a lot of stuff just to get a couple running.
I went to wal-mart and theisens and found the cheaper of the 2 for 3.3 gal. tank, hose w/primer and fitting is theisens,almost $10 cheaper. paid $40 for everything. if I'm lucky, I might have one running this weekend...
thats funny you mention doubling them, I was joking with a guy at work about that. It would be cool though.

Re: need help with 9.5

YES that is an excellent deal, and might I suggest that if you have one that is junk, maybe a bad powerhead, bring it into your shop and completely disassemble it soup to nuts. Photograph every detail as you go and store all the parts neatly and seperatly. The first 9.5 you tear apart will be an invaluable experiance it may seem a little complicated at first. But then when you have to take apart another one for repairs ( and you will have to take apart another one!) you will allready know what not to do from the first one and you will most likely allready have the replacement parts handy. I speak from experiance the 9.5 has a couple of tricky areas, like the shifter linkage. Better to bust a bolt on a junker, just don't forget to take digital pictures. Then you can also post the picture when you ask a question. Good luck.

Re: need help with 9.5

the one with no year has bad mounts, another has froze linkage, water came out of the lower on 2 of the units, compression through all motors is 60-80. mice got into one, but the wires look untouched. whats normal compression for these? spark is an issue too. I put a screwdriver in the wire and held it while I pulled and there was nothing on a couple of em. I was just trying to figure out the best one to start with and the best one for parts. I need to get my manual probably before I go any farther.

Re: need help with 9.5

So there not all perfect? Not to worry. You'll get them going in time. Your compression is good on all. Anything 60 and above would be fine in my opinion, as long as they are within 10% of each other. The higher the better of course. The first link at the top of this forum has a ton of really good information you can use. Lots of good stuff from many of the "Top Guns" of this forum. You can use these to do lots of checks while waiting for a manual. It is the first link and reads "Top Secret Stuff". Look at the link for Replacing points and coils for instance. But look at them all and you will have lots to do before the manual arrives. Even a frozen shifter may just be an adjustment so don't count it out yet. Have fun and keep us informed on your progress. Rick.

Re: need help with 9.5

glad 60 is ok. it sounded low because I am used to having 140 in my car, lol. I am getting my manual online in file format for $3, I hope to get it today. I will still be looking for a book though. I am just anxious to do something with one of em. I have been running a old fleetwin 7.5 for a while and I want to see the difference in power. I will get the serial numbers off it next time I get a chance, it was a hand me down from my grandfather and always works as long as I could remember. we have had good luck with that thing.

Re: need help with 9.5

You're probably going to discover that manual isn't worth the $3 you paid for it. Bite the bullet and look for an OEM manual.

Re: need help with 9.5

its the clymer edition, it has some useful info but doesn't get into great detail. it will work for now. and I will probably be ordering a omc book by the end of the weekend. I wanted to know what direction to go with no spark. shouldn't you be able to just pull a plug, connect the wire, pull and see a spark? Clymer said to pull the boot off the wire and hold it near the plug to see a spark. which is best?

Re: need help with 9.5

What you want to do is make or buy a spark tester. If you do a search here you'll get a zillion or so things to look at.

 

[tashasdaddy]

Re: need help with 9.5

spark tester any auto parts store.

 

[xirocrtx]

Re: need help with 9.5

right, I got one of those at work, never thought to use it though. duh. I will grab it and see how many have a good spark. thanks.
