I recently purchased a 1954 Johnson model CD 5.5 Seahorse. First question is what should i check before trying to fire up? and does anyone know a good site for OEM parts? i would like to keep the engine original and find an original two line gas tank.
 
Do a complete evaluation of the motor before spending money on parts.-----Take it all apart , including the lower unit.
 
Can you post a few pictures of it? Start with a compression test, both plugs out.....nice swift pull. Should build to max by 5 or 6 pulls. If it has been sitting for awhile you might want to squirt some mixed gas and oil in the carburetor first while somebody is pulling it over to help lubricate the internals. It really depends on the outward appearance and overall condition of the motor as to how far you want to tear it down. I look for previous work right away like paint knocked off screws/bolts, action on flywheel nut and carburetor fasteners. There is an access plate on top of flywheel and you can look in to see if the coils are cracked and/or have been replaced. I have a 1954 Johnson 5.5 horsepower that I bought down near the Twin Cities from an old guy. He had broken the recoil and was unable to fix it. He had bought it brand new. It was in his shed and a mouse had built a nest inside it really stunk. Some of the parts were missing including the fuel tank the fuel hose and the connector. My initial examination proved it was a virgin, never been opened up. Got it home and put back together with new coils, wires, and cleaned up the points. Mice had chewed up the plug wires pretty bad. Then decided to start it after cleaning the carburetor........without checking the water pump impeller. It was obvious that it had the original impeller because all the paint was still on the bolts. These impellers and all rubber components, back in the fifties, were made of high-quality pure latex rubber. It started immediately in the barrel and begin pumping large amount of water out the exhaust port in the rear of the midsection. I have used it many times over the last three years and it continues to pump water and operate perfectly. They just don't make stuff like this anymore.

I've bought the majority of all of my old outboard motor parts here on MarineEngine.com. You might find some parts cheaper some place else but you'll not find shipping any where as fast. And I've never gotten the wrong parts shipped to me from MarineEngine.

That's the least I can do for them for providing this forum where I've learned a lot from these old geezers that hang out here. :D
