Cool deal. Yea, something seems to be wrong with picture uploading here right now. I uploaded some yesterday but they don't show up. The site has been under construction here as of lately.

Yea, $197 (150 Euro) isn't much money for an old outboard here in the Netherlands .

$200 isn't bad at all, even here in the States. I love the paint job on the '58 models. Can't wait to see it come to life.

Yep, you can see that little Evinrude Fisherman in my signature. It's the same year as your motor there. I just brought that one back to life last weekend. I probably have about $150 into it, and that's including the motor itself (tank included), new coils with wires, new lower unit seals and impeller. All tuned and ready to hit the water. With a little bit of careful shopping and a little extra time, a guy can have a good little fishin motor for cheap. Good luck with it and keep us posted on the project.

Re: Tune-Up 1958 Johnson Seahorse 7.5hp

One question... Why is there written (near the choke) ''pull to stop'' if you can stop the motor by turning the gas/steering handle?

Re: Tune-Up 1958 Johnson Seahorse 7.5hp

Today I had little time, so the only thing I did was cleaning some smaller parts and checking for spark on both cilinders. The spark was very good, stron and blue...
I hope I'll able to clean the carburator tomorrow .
I keep you updated!

Re: Tune-Up 1958 Johnson Seahorse 7.5hp

Today I finished the carburator tune-up, so in a few days I'll be able to start the motor and get it running.
The motor has all the things that are need to start and run it:
1. Compression
2. Spark
3. Fuel and air (carburator is clean)
4. Shifthandle works perfect (it goes in forward, neutral and reverse very smooth)

I keep you updated !

Greetings

Re: Tune-Up 1958 Johnson Seahorse 7.5hp

Great news JohnRudeMan. I'm not sure why the choke would say "pull to stop", however. Are you sure it doesn't say "Pull to start"? You generally have to choke the motor upon cold start ups to provide a "rich" mixture to the motor, but once the motor has warmed up, you usually don't need to use it again. Although, I suppose you could kill the motor by pulling the choke, thereby flooding the cylinders and causing the motor to die, but I've never done that. Many of the older model OMC motors, without factory kill switches were designed to be shut off by simply turning the throttle all the way down to its lowest position thereby decreasing the spark to such a point that the motor died. Congratulations again on the progress. Keep us posted.

Nice score! I see that it still has the 1958 Emblem on the front. The tank looks like a 1954-55 with the metal primer button. One thing I notice in this picture: http://i1097.photobucket.com/albums/g348/war-searcher/P1030008.jpg is that there is an original OMC accessory adaptor for fitting remote controls.

The stop button was only installed on the 10-horse and larger motors back then.

Your motor looks like the very same model as my 7?. I'm curious as to why there is no horsepower decal on the cowl of your motor.

@kfa4303: I'm sure it says 'pull to stop'. Here is a link to the motor decal: http://www.nymarine.ca/58JO75WEBPIC.gif
You can see the 'pull to stop' is there too. This is my motor: http://i1097.photobucket.com/albums/g348/war-searcher/P1030007.jpg

@TN-25: I think you're right with the tank, it's certainly a 1955 tank. The previous owner has told me that it was the original tank, so I assumed it was... but you're right it's a '55 .
The 7? hp decal has simply disappeared through the years of sitting (about 20 years)... as you take a closer look, you can see that there must have been the 7? decal on the side of the motor.
I'll try to take a picture from it .

Re: Tune-Up 1958 Johnson Seahorse 7.5hp

so it does. I suppose they just used the choke to flood the engine and get it to stop. Funny, because in the decal for the starting instructions tell you to pull the choke to start the motor too. Go figure. Keep us posted.

Re: Tune-Up 1958 Johnson Seahorse 7.5hp

I ran the motor about 15 minutes ago! After sitting for 20 years, it still runs like new!
I put 16:1 gas in the tank, it started after the fourth pull!
The only matter was that it didn't pump water well, so after one minute running I turned the motor off
I hope I'll be able to replace the waterpump this week.
When the motor is running well, I'll post a video of it .

I keep you updated!

Re: Tune-Up 1958 Johnson Seahorse 7.5hp

Excellent!!!! Make sure you are running it in a test tank with water filled to about and inch or two below the main exhaust port. These old motors can not run on muffs and do not have a "pee" stream or tell-tale like modern motors. Here's a vid of one running so you'll not what to expect. Notice how low and slow the idle is. Purrrrrrrfect!!! Congratulations!

Does the remote-control fitting makes the motor worth more?

Re: Tune-Up 1958 Johnson Seahorse 7.5hp

Hello again JohnRudeMan. It's nice that your motor has the control cable holders, but I don't think it adds much monetary value to the motor necessarily. You can usually get replacements for under $10 US, but having them will obviously save you the effort and expense of having to track some down. If you decide to hook up vintage controls, you can check sites like ebay, of course, but you may also want to check aomci.org. They are an organization dedicated to keeping these old motors running. Many of the members have spare parts and accessories for these vintage motors and they are very generous and helpful. While you would still have to pay for shipping, the price of the parts would almost surely be less than on any retail site. The cables themselves are identical to one another save for the fittings at the motor end. You can get them right here at iboats. One cable will need a throttle fitting, one will need a shift fitting. Again, check online for these parts. They can be between $10-$20 (w/out shipping). Of course then you need a steering wheel and helm, etc... While no one part is particularly expensive, all of the bits and pieces can add up quick ("nickle and dime you" as we say here in the States). Here's a link if you decide to give it a go.
