1950's vintage 12hp seaking

[saintj]

Hi, I am brand new to this forum site. I have a 12hp seaking (not sure who it was made by, Gale ??? Made in early 50's )I recently revived this old motor ( bought new by dad when he was a kid ) with a couple of new coils and a carburetor rebuild. Runs like a champ. Does any one know of a way to convert this thing from an intragal tank to a remote one. ( ie fuel pump etc. ) Any info greatly appreciated.

Re: 1950's vintage 12hp seaking

Hi,<br /><br />Yup, that's a Gale motor, made by OMC. You can convert it to a remote tank, for sure. You'll need a fuel pump and will have to install a fitting on the engine that will pick up the pulses from the crankcase. A careful inspection may actually lead you to one that's already there, but plugged. I don't have an image of your outboard in my head, but you should find a pair of transfer covers on one side of the engine. You can remove one and drill and tap it for a 1/8" pip fitting to pick up the pulses.<br /><br />Then, you'll need a generic pulse-type fuel pump large enough to handle an engine of this size. You may have to do some adapting.<br /><br />You'll need a fuel connector, like the normal ones on OMC engines, and will have to mount it to the outside of the outboard. <br /><br />Then it's just a matter of running fuel lines from the connector to the intake side of the pump and from the output side of the pump to the carb on your engine. Another hose goes from the pulse connector on the pump to your new connector on the transfer port cover.<br /><br />From there, you're home free.

Thank you. I thought it could possibly be done I just didn't know how to do it. Hard pouring gas on a rough lake. Are the pumps readily available?Where can I find one ?

Well, they aren't that hard to find, but you'll need one that has enough capacity for your 12 hp motor. You could use one from your Johnnyrude dealer that's for a 9.9 or 15hp motor. The only thing to watch for is that it has 3 outlets. Some attach directly to the pulse source, and that would be a problem.<br /><br />Another source might be a pump for one of the larger lawn tractors. Check with a place that repairs these. Tell them what you're doing and that you need one with three hose connectors. They'll have something for you. Be sure to mention the horsepower.<br /><br />The inlet fitting from the tank you'll probably have to get at a johnnyrude dealer. The tank, bulb, and hose, you can get at any marine supply place.<br /><br />Just remember to remove that transfer port cover before drilling and tapping it for the fitting. You don't want crud getting into your crankcase.

Here is a fuel pump option:<br /><br />The Mikuni DF-52. About $35 from places like:<br /> http://www.kartoramainc.com/674370.html <br /><br />This is a go-kart fuel pump, with a high volume output. It would be adequate for your use.<br /><br />

Re: 1950's vintage 12hp seaking

Finally, I am working on this outboard again. I pulled off the transfer port covers from both sides of the engine. The tranfer port on this engine in made into the block. The cover is over the water jacket surrounding the jug. If I drill into this I will get shaving into the intake port and engine. I hate to pull the engine apart because now I am not sure who made the engine. It was made in 1952 and the model # 25gg9018. Is it made by Gale? Not sure who it was made by now. Is there any other way to add a fuel pump to this engine?

Re: 1950's vintage 12hp seaking

It's definitely a '52 12hp Gale. I *think* that one is like the old Evinrude Fastwin (19.94 CID block). Your description certainly fits. The covers are (generally) large, square plates right?<br /><br />If so, probably the most practical way to hook up the pump is to remove the intake and reed plate, then "remove" one of the check valves for the pressure system and block off the other. Then reassemble and use the old pressure line to run the pump.<br />If the check valve restricts the pressure pulse, enlarge it. Probably anything 3/16"+ would be fine.<br /><br />I think CATransplant was thinking of the later Fastwin engines (22.0 CID). So was I, sorry about that!

Re: 1950's vintage 12hp seaking

Yes, Paul you are right square plates on both sides of engine. One just covers the water jacket basically on the intake side. The other side covers the exhaust port and keeps it separate from the water jacket. This is still a Gale made outboard then? Are parts still available for this motor? It has a Tillotson carb on it Model MD54A. I would like to get a rebuild kit if possible. Also what about ignition parts. Breaker points, condenser etc. I,m actually thinking about putting an electric universal fuel pump on it since it will back up my I/O anyway. Thanks John

Re: 1950's vintage 12hp seaking

Is it a Gale? Absolutely. No question.<br /><br />Parts are still available, but somewhat hard to find. Carb kits don't appear to be available from Bombardier anymore.<br />Tillotson MD carb:<br /> http://64.180.101.188/cscc.nsf/e723...7a5285cda46690f288256e0f00770f39?OpenDocument <br />Does this look anything like yours?<br /><br />If that's got the older ignition system, then points & condensors can still be purchased new. Coils cannot but they're rarely a problem. If it's the newer system, then points, condensors, and ignition coils are all easily & cheaply available. The coils are often a problem.<br />They switched systems around that time, so I'm not sure which one you have.<br /><br />Personally I shy away from electric pumps due to the obvious safety problems. I don't think it's possible to mount them under the cowl, because I don't think they're self-priming. Plus I don't like to have to rely on the +12v system.
