1956? 12hp, Sea King

[Paramedpete]

Hello all and greetings from Bastrop Texas. Im new!!!!!! So here we go. I believe i have a 12hp 1956 Sea King I just aquired (not sure if thats the year or not and thats what the guy told me). First of all where can i find the model #, secondly where can I find parts for it. I would like to restore it. It runs realllllllllllllllllllly hard and not for very long. I took apart the fuel pump and it was pretty hard and crusty, points are set and plugs look good, so I guess thats a good place to start. Any help out there?!!!!! Thanks to all, and look forward to more from yall.

Re: 1956? 12hp, Sea King

There should be a number on the top of the mounting bracket.
something like 225-3609.It was built by the Gale devision of OMC and
you are lucky it shares lots with the Evinrude Johnson motors of that time.
Ignition,fuel and cooling parts may be available right here at iboats.Under the 15hp E/J motors .
Similar E/J didn't use a fuel pump at that time but later pumps may work for you.A service manual for the 15 hp E/J motors 53-56 should serve you well.

Re: 1956? 12hp, Sea King

Hey Pete...another Texican on the board. Your Sea King was made by OMC/Evinrude/Johnson by their Gale Mfg. division for Monkey Wards. There should be a plate on the front of the transom clamp with a series of numbers, and GG in there somewhere. If yours is a 56, those numbers will be reversed in the string, like 65GGXXXX. Any good OMC dealer can get parts for it, cause it uses the same parts as Evinrude/Johnsons of that era, points/coils/condensors/impellers, etc. The fuel pump diaphragm (rubber) is probably shot...new pump costs less than $50, especially on the auction sites. Probably need to pull the carb, soak it in cleaner, blow it out with compressed air and reassemble/install. It uses a Champion J6C or J4C plug gapped at .030, points are set at .020 and fuel/oil mix ratio is 16:1...about 1/2 pint oil per gallon. Let us know how it goes...somewhere on the board is post called "awakening a sleeping outboard," has most of the info you will need to get it running sweetly again.

WOW, you guys are awesome. I didnt think i would get a reply so fast, I am thoroughly IMPRESSED. Thank you all so much!!!!!!!!!!!!!

Re: 1956? 12hp, Sea King

OK, well , bad news. I have 4 nicely spaced rivets without a plate. How long and how similar are the parts for that era, give or take 3-5 yrs. Im pretty sure its not older than 1956. If I take a picture of it , can I send it to someone to idenify, or maybe a few part #'s off the motor some can identify. HHHHEEEEELLLPPPPPP.!!!!

Hey Pete,
Try and post a photo. If it has full F-N-R shift, it's got to be 55 or later. Earlier models were direct drive I think, or just had a F and N lever. If the top cowl/cover is kinda rectangular with rounded off corners, it fits the 55-59 design scheme...the top cowl got more boxy with sharp corners after 59.

I don't know how I got into the Goodyear mode but the same applies to your Sea King.If it has a remote tank it resembles the Gale 12D13 which appeard in 56.54-55 Sea King uses a integral tank no remote tank.56 Sea King GG-9021A Uses a 17.89 cu. in powerhead this evolved into a 15hp in 1960 using a 19.94 cu in block.The 12,15,18 and 20hp OMC motors are all covered in the same chapter of my after market manual.12 and 15 use
J6C Champion plug set at .030.points set at .020,Fuel mix is 24:1 stick with it as the Gale built motors use Friction bearings at the lower main bearing and piston pin.
By the way the 12hp was available in Electric start.

Re: 1956? 12hp, Sea King

OK, here are the possibilities:
The motor came out in 1954-55 as a GG-9016A (Gale model 12D11)
In 1956 it was a GG9016B (Gale model 12S12)
in 1957 it was a GG9016C (Gale model 12S13)
In 1958 it was a GG8978A (Gale model 12S15)

Without a whole lot of study on both of our parts, that's as good as I can tell you.

As I recall this is a full shift motor with remote tank.I believe that would be a 12D13,12D14,in 56.

Nope, I believe the numbers I quoted are correct. It came with an integral tank and a fuel pump kit & remote tank were sold as an accessory. It used the old style exhaust housing without rubber mounts. Note the dead give-away notch.

Re: 1956? 12hp, Sea King

Hey guys, yall are awesome, I think were getting reallllllllllllly close. if these are the #'s, where am i going to be able to refence them as far as getting the parts that i need. I found the retro fuel pump that should fit (18-7350 evinrude 1992 or older on this sight), but the way its configured and how it will mount, it doesnt look like it will fit. It appears to mount diagonally if im looking at it right . Am i looking at it right ? incidently the motor is set up for remote tank and intagral tank. The red paint on top is the intagral tank ( not to insult anyone's inteligents) this is not the original paint on this and you can barely see the gas cap on top in these pics.

Re: 1956? 12hp, Sea King

The original pump was part number 376372 wich is now superceded by 388685, but I'm not going to sit here and suggest that BRP has checked to see if it will fit that old Gale with a gas tank. Maybe yes, maybe no.

Now: I would be more inclined to select the 18-7351. It is a better pump than the 18-7350. However, it may be taller than the original Gale pump. If there is room for it in there, that is the one to get. Whichever one you get, you will have to re-route the hoses. Remember, the filter cover (big inlet hose) can be rotated to a different position if that helps. You can even go to the extreme of mounting the pump upside down if that helps.

Re: 1956? 12hp, Sea King

I think you may be right about the pump. I actually thought of the same thing, but i wanted to be sure. their is plenty of room for the taller pump. Is it the same screw pattern, i mean will it match up to the hole, because the 7351 is for a 25hp i believe and do i need to worry about a higher fuel flow rate or is that relative. I guess it probably wouldnt matter, the carb is only going to except so much fuel, right? Incidently the PN # you mentioned didnt coralate. The # i found was a 304 sumpin sumpin. at this point im willing to just take a chance and purchase it to see. Based on the pics you saw are we sure its a Sea King, Im sure we would have mentioned that if it wasnt:redface: To throw another perverbeal (spelling) wrench in the wheel or (boat motor). what about lowerend gaskits and carb kit for this gem.

Again, I cant tell ya'll enough how great this is being able to do this online with you guys, your knowledge is unsurpassed.

Thanks, Pete

Just a side note. How do you get promoted on this sight. I guess you need to actually know something about what we are talkng about.

I stand corrected. I wasn't aware it had the integral tank.
