Johnson seahorse 1959?

[walleyecleaver]

Hello all
I am new here, and am very excited about a 9.9 johnson seahorse I just acquired.
Can anyone confirm the year of my engine?
model # is QD-17
serial # 198358
from looking thru posts it looks as if I own a 1959, but am not sure.
I am also curious about any other info that my model/serial # may tell me?
Thanks in advance

Sir you are the proud owner of 1956 Johnson 10hp.

Here is couple of links that will get you familiar with your motor.

http://www.sschapterpsa.com/ramblings/johnson_QD.htm (supplied by the machinist here on our forum) Great information.

http://www.marineengine.com/parts/v...ntage-evinrude-johnson/376747/37674700001.htm (part catalog and breakdown of your motor)

I would buy a service manual for your motor. Can be purchased here on Iboats

http://www.outboardbooks.com/index.cfm?fuseaction=models.main&year=1956&ID=153024 (I believe Kencook is the authorized Johnson/Evinrude service literature provider)

There a bunch of experts on this forum familiar with your motor and would love nothing better than to see her running and making blue smoke again.

Awesome thanks alot.
I am going to check these links out now.
I'll post back and let you know what happens.
I'll make sure to add some pictures and maybe throw some video links to youtube or something.
Thanks again

A buddy of mine is lookin for an old service manual for me.
It's nice to that there is even a lot of resources on here to help me with proper maintenance issues.

I took some footage of the first official start and posted it here http://www.youtube.com/watch?v=t85XnO_4lSA

It is not the greatest quality but I plan on getting better footage on her maiden voyage.
I'll keep them posted for sure.
I am going to look around for some carb cleaning kits or just do what I can in the meantime to fix her up a bit. Change the plugs n what not.
From what I read around here it looks as if it's in my best interest to use a gas ratio of closer to 25:1. I guess it would be a good idea to find out if I have needle injectors or brushes. I am not to educated about that stuff but apparently that will be a factor for determining if I want a richer mixture or leaner mixture. Not too sure though. More reading to do.

You have a high and low speed needle (low top, high bottom) on the carb used to control mixture at idle and at high speed. High speed can only be adjusted on the boat while running it at high speed, low at idle of course but will act differently in the lake.

Re: Johnson seahorse 1959?

Yes I've been looking at those dials for a bit and have noticed them on some other videos.
My dials are barely readable and I'm not familiar with them at all.
So it sounds like your telling me that they control mixture. Is that air to gas mixture it controls?
Is there anything in particular I should know about those mixtures. What is the point of tweaking the mixture?
Does that mean if for example I'm at idle and the motor sounds rough I can tweak it a bit( turn up or down the low speed dial)? And does that mean if at high speed it sounds rough then I tweak the high speed dial?

I am getting very excited to take this boat on the water.

Your motor is nice and seems to be running pretty good for initial repair and start up.... I see your gonna have fun with her!!

Here is a link from the top secret file section that describes how to adjust your carbs.

Definitely stay with the 24:1 or 25:1 fuel/oil ratio. Don't let someone tell that with today's oils that you can go 40 or 50:1 ratio. If you do, you run the risk of shortening the life of the motor. The experts on Antique Outboard Motor Club will tell you that keeping it 24:1 will protect your motor and prolong the life of it. Today's oils are better quality and don't smoke as much either. Synthetic 2cylcle TWC-3 marine oil is a little more expensive but is biodegradable. I've converted....little extra coin to protect the lakes.

Re: Johnson seahorse 1959?

Thank you for the links, I am going to check'em right now.

To know that there is biodegradable oil for my mixture is great. I will definitely grab some. I will also use a richer mixture like you confirm.

I just wasn't sure because I read somewhere on here that a richer mixture is worse for certain engines. Something along the lines of needles or brushes....
I am not sure what mine has but it sounds like I am just confusing myself and that I should use a richer mixture. So I definitely will.
I mean it makes sense that the extra oil will be good for my older engine as far as extra lubrication goes and what not so....

Thanks a lot

Yeah when I started it up for the first time and smelled that blue smoke it made my body itchy. Can't wait. This is the first boat I've had for a while so....
