Sea King 5hp missing carb parts?

[asdasc]

Hi All,

I am working on a 1954 5hp Sea King (Gale made) GG9015A. The lower cowls were missing, but everything moves freely with good compression and the lower unit feels pretty good and shifts into neutral ok. I checked the coils and of course they are cracked up and need replaced. I already ordered them and the tune up kit.

The concern I have is that the carb looks like it might be missing something? Or at least an air box or something? Can you tell from the picture? Will it run without them until I can find one? I will find a carb kit for it and rebuild the carbs as well, but the potentially missing carb parts could be a showstopper.

Lastly, does anyone know if the water pump impeller is behind the prop or up in the leg like my Johnson FD13 18hp?

Thanks,

Some of them have a little, bolt-on carb throat cover...looks all there otherwise.

OK, I can live without a cosmetic cover if that is all it was. There may also be something missing from the choke on the other side, but it seems so gummed up I can't tell yet.

I will disassemble it and clean it good and go from there.

Thanks!

Has a variable venturi carb.Kind of an odd ball carb but simple, easy to work on. It uses a primer by turning the high speed knob all the way to the left there is a cam on the knob
pushes a lever against a pin sticking out the top of the float cover.simply flooding the carb hold 3 or 4 seconds.(instructions say 10 seconds) seems long to me, return to run .Pull starter till it ingages then crank.

Re: Sea King 5hp missing carb parts?

It looks like your carburetor is all there. They don't have anything over the opening. Turning the knob all the way to the left holds the float pin down, flooding the carburetor for enriching the mix for starting, instead of a choke. That carburetor is about as simple as they get. Don't try to complicate it.

The water pump is in the bulge about a few inches above the flat anti-cavitation plate. The impeller is the same as a TN Johnson, obsolete. But the good news is that the 5.5hp impeller (from iboats) will fit if you ream the center hole out .010".

Re: Sea King 5hp missing carb parts?

got two of those carbs laying around. that is all there is to them. The intake is part of the carb so all you need to so it take the screws off for the intake and the whole thing will come off. don't know if kits are available, but those are simple carbs and more than likely take it apart and clean it and it will run fine. I would venture to say that has a cork float in it so you may think of sanding then recoating with fuel proof dope.

Re: Sea King 5hp missing carb parts?

Thanks guys, that is what I had hoped. The basic function looks similar to the carb on the A-50. Variable Ventury, eh? Sounds like a good way to discribe it. With the info that the carb looks complete enough, and now knowing more about the water pump, this project is a 'go'. Hopefully I will soon have a nice running 5hp and can sell my Eska!

The only bummer is that I can't get to until next weekend when I go back out to the cottage. This time I will remember to bring my flywheel puller and a couple other key tools.

If I run into anything else, I will let you know.

Re: Sea King 5hp missing carb parts?

OK,that went pretty well, but I still have questions.

The lower leg came off ok, but I didn't realize that this was open to the fluid, so I am glad I held it upright. I didn't get to the water pump impeller. It is hid behind another part ABOVE the lower unit, not as part of it like my 18hp Johnson. There were a couple more screw going up into the leg, but didn't keep taking things apart as it would come apart easily. There was another big nut that may have been the key to removal.

On the carb, it was a mess and I got it cleaned up REALLY nice. I was surprised that there was no gasket on the fuel bowl cover or on the right side under the rich/lean adjust. Is this correct? Or should they be there? Where can I find a carb gasket set? Or at least the packing for the 2 valves and the base gasket? Any help would be appreciated.

The flywheel came off well and the coils were trashed. I now have great spark.

All I need to do is put packing in the carb and reattach it and I am ready to go!

Thanks in advance,

Re: Sea King 5hp missing carb parts?

No gasket on the float bowl. Packings are still available thru Evinrude dealers, if you have the part numbers. They are NOT the same packings as most OMC carbs, reason being that they are used and abused much more, every time youprime the motor.

Disconnect the clutch cable at the neutral lever, then the clutch plate and pump will come down and away. The cable feeds back up through a tube, so don't fret about getting it back. Unless it is frayed at the top end..then it becomes a problem.

Didn't dump the oil on your shoes?? Shucks, that's half the fun.

Re: Sea King 5hp missing carb parts?

Thanks FR, I will take another look at that.

Yeah, I can't beleive I didn't dump it all over the floor of the cottage. I got lucky and noticed it as soon as I saw all the goop on the drive shaft sludging down. I had just let the lower unit drain for a week, then refilled it and messed with the coils and tune up. I was surprised how much sludge was still in there, so I drained it again and rinsed it all with kerosene and cleaned it good. By the way, the crown gear that the driveshaft slips into tipped over sideways in there, so we ended up disassembling much of the lower unit to get that back right. It seems to work fine now.

Any idea of the part number on the packings? I suppose I should find a parts manual for this motor.

Thanks again,

Does that mean that Sierra part 18-7106 won't work? Would it get me by? Or is there someone who might have the correct ones?

Thanks in advance

Re: Sea King 5hp missing carb parts?

Can someone help me out with the correct evinrude part number on the packings? I can't seem to find it anywhere. I really want to get this one on the water. If there is a part number on the base gasket also, that would be great.

Thanks in advance,

Re: Sea King 5hp missing carb parts?

That's the same as my Gale 5D10, what do you mean by the packing on the carb?

Re: Sea King 5hp missing carb parts?

The two knobs on the front have leather-ish washers inside to provide a seal and also the friction needed so that they stay put once adjusted. I need to replace them and can't seem to figure out what to order.

From what I understand, they are the same carbs used on some older Johnsons. I believe it is the TN-25 thru TN-28, but I am not 100% sure.

Thanks,

Re: Sea King 5hp missing carb parts?

I don't know that the carbs were used on anything else aside from the Gales, I could be wrong though.

Re: Sea King 5hp missing carb parts?

Needle valve packing is part number 550259. Fuel valve packing is number 551097.
Evinrude used the carburetor briefly, Johnson never did. But it was used for a ton of Gale models.

Re: Sea King 5hp missing carb parts?

Thanks a bunch FR, as always. I will see if I can find some this afternoon by calling around. I called iBoats yesterday, and didn't find them but gave me the phone number for Sierra tech support to see if they can cross them. Once I find them I will post where for future reference.

If I don't find them thru Sierra Tech Support, I will try laingsoutboard and NAPA next.
