- This is the same 18hp that's in my other video. Ben you were right not a thing wrong with it like you said. It's on a StarCraft SF-14 very deep V 14ft boat 68" wide and the GPS showed 24MPH. I said in the video it's 1956 but we all know it's not. sorry
Beautiful motor. Runs great. Good job.
Thanks, and Merry Christmas
What a smooth running motor👍Got a 56" 15 that isn't as pretty but runs like a Swiss watch
Probably the VERY BEST motor in it's h.p. range! Way more reliable thaan the Merc, or the Chrysler in this range! Can't kill 'em!!!!
Sweet running 18! They sure are great motors! Great video
Sweet motor! Gotta love those 50s OMCs. I have a similar 18hp '57 Evinrude Fastwin. Great, smooth running motor, throttles down to slow troll really well, and pretty quiet, too, as long as I keep the hood latch from clanking against the hood.
Wow our family has this motor. Never done anything work just new plugs every few years. Used it on a 8 foot hydroplane we flew around the lake.
Ya they are very nice, long lasting motors
Great sounding and looking motor!
thanks
Very nice!
thanks
Ahhh -- a fellow Hoosier, and no too far from me.
I become the owner of a 1959 Johnson FD-13 18hp. I bought it off Craigslist for $200 to go on a 1975 Sears Gamefisher 14' Tri-hull I am restoring. One the advice of an aircraft mechanic I know - he said, since I do not know how long it was stored, that before I run it to fill the cylinders with Marvel Mystery Oil and let it sit 24 hours (apparently this is what they do with old aircraft engines) to make sure that the rings were not stuck and or rusted. He said then to pump the motor over slowly to push the oil out ---so on and so forth.
I did all that, I had to rebuild the leaky carb (leaky being an understatement), it needs a slow idle needle still (tip on existing is bent) ...but other than that I have it running well. Runs smooth, runs through the throttle fine, does not cough or spit when coming back down to slow speeds (all of this is in a trough of course), and idles well when turned to "slow" ----
Is there anything else I should look for or consider looking into for this motor?
Or should I figure "if it is running fine is probably is fine"?
I would change out water pump and lower gear case seals and gear oil
Outboard Fun ...gear oil of course is planned. I will add the seals and pump to the list. thanks.
That Baby runs Cadillac Smooth! Nice Motor.
I just got one that the junk man got and was gonna throw it away. It was locked. I put sea foam in it and it turns over with good compression. Missing tiller handle.
What are you running for fuel/oil ratio? Factory recommendation back then was 24:1 but they ARE "fully jeweled" ie. needle bearings on both ends of the con rods so they'll run 50:1 w/ no problem. OMC still had models with the old bronze bushings so they didn't change their official mixture until all of those were jeweled which I believe was 1962. And, back then you were using basically 'straight weight" non-detergent crankcase oil for lubricant not the much better TC-W3 let alone plain ol' TC-W! That's what I run in my FD-12 and I don't expect to ever have a bearing failure or scuffed cylinder wall.
I run it at 42:1 I know this is FULL ROLLER BEARING MOTOR
I have 5 gallons tank I mix in then pour in the motor's tank. I put 16oz oil to 5 gallons then just keeping toping off the pressure tank before I go out I never go out with the tank in boat being full. Then when I use up can in my gar. I go and mix up 5 more gallons but your right I use 40 to 1 not 42
Would you fo a video tuning and setting up carbs on some of you 50’s and 60’s motors and post to help the rest of us with maintenaning these old machines
I'm done working on outboards. Watch this guys videos he does it the right way.ruclips.net/user/cajuncookonefeed?disable_polymer=1
sounds great to me. The 18s have some noticeable gear whine, which is normal for the design.
Awesome motor there
Some one gave me this(making room in his garage) It pulls so hard! I would love to get and electric start for it. I haven't got it running yet Thinking about moding the carb so it accepts a NON pressurized fuel tank.
The carb don't need a mod you have to add a fuel pump to the motor
Beautiful
I had this one on a 8foot hydro lots of fun
I bet that thing was like jet boat with 18hp on it
Nice looking motor but too bad the original encapsulated plastic front badge gone. I have two motors just like that both with decent badges. Both run and have been converted to single-line tanks - it's not a tough job - just cannibalize an intake port cover and pump from a 1960 and up 18 and put a 1/8" pipe plug in the front.
Now I got it running even better then in this video. I checked the timing and adjusted the points again and its running real good now.
please help ic you can. i have what i believe is a 59 18hp golden jubalee and the water pump isnt working but i dont know how to disconnect the gear leaver linkages to fix it. any ideas?
You have to remove that little cover on the side of the motor about half up from the water pump. It' haled on with just two screws. Here's a video showing how to do it. Your motor will have only the one cover on the outside not 2 like in this video but the linkage is the same.
I love those 18 hp my dad owned one i learned to drive that motor starting when i was 6 those babys haul ass when ur in the boat by urself
also never slowly put that baby in gear it ruins the tranny u wanna put those old johnsons in gear right away
One more reccomendation run that baby out of gas when u come to the dock to take her outta the water that way the gas wont varnish up in the carb
You said 1956 ? Or 1958 ?
1958
Is that a 15 or 20"?
The old OMC were 18" or 23" I'm don't sure what year the motors went to the 15" and 20". If you look close in my videos I have built the transom up the 18" to match up my 1950"s OMC motors
thank you very much, I have the same motor and I was wondering what my transom height should be
Check the points one more time, youve got one just a little bit more than spec which is 20
OK
So, you're saying you can tell, from the audio and visual on this, that one cylinder's timing is a tad advanced? 'Cuz that would be the case if point gap were too wide - the rubbing block would ride up on the ignition cam early and the contacts would open sooner. Could lead to detonation if it's too far off, but honestly these old magneto motors never seemed to be that fussy - lots of 'em were probably gapped using a MATCHBOOK COVER Back in the Day with no ill effects.
I now have one of the OMC timing fixtures. When I done this one I didn't have it. This was my first 18hp. I now have about six of then. I no longer have this one. What was causing the miss on this one ended up bring a bad crank seal.
Here is my latest 18hpruclips.net/video/SabGzGJ-Qek/видео.html
Its a 58 not a 56
I have an original one for sale .
So do I this one ruclips.net/video/SabGzGJ-Qek/видео.html I'm selling all my motors and my boat
Beautiful
