1956 Johnson Javelin Water flow question

Re: 1956 Johnson Javelin Water flow question

send a pic of your carb. I agree with the others that is sounds like you have an electric choke solenoid on your carb.Which makes me think more and more your motor is a hybrid. Some one put a carb off an electric start model on it and just didnt' hook up the wires. Even with the electric solenoid you should still be able to manually operate the choke with the pull knob. Just manually operate it and forget about the solenoid. you can take it off if you want it won't hurt anything. Send it to me I can use another one.

the choke nob will turn the choke on but when you puch it to turn it off it stays on and i have to reach in and grab the linkage to turn it off....and this has everything to do with that cylinder....

Re: 1956 Johnson Javelin Water flow question

That's not an electric pump, by the way. There's a FAQ here about switching from pressure tank to fuel pump tank. It's easy on your engine, but read the information here. That pump number is fine.

i read the FAQ but was still unsure on how to do it.. but i guess once i have the pump it will make more sence...

also what else do i need besides that pump?

thanks guys....this is the most helpful forum ive ever read...

Re: 1956 Johnson Javelin Water flow question

and how exactly does this convert it to a suction type system? any explanation on how the pump does it?

Re: 1956 Johnson Javelin Water flow question

ALright, I read page two of this thing and I am UPSET with boatbouy. I tried to click the pic of his crappy looking javelin and couldn't blow it up! That thing was definitely "fully dressed"!
If my pressure tank wasnt' rusty I'd put a 25 dollar rebuild kit on it and forget the fuel pump. the fuel pump conversions do work as expected, though.
Good luck----I have to ask, did you check the lower unit oil? I wouldn't run it anymore unless I knew for a fact that it didn't have any water in it. Water will ruin the rascal. Buy you a bag of l.u. drain screw crush washers, you'll need 'em and they're cheap.

i have the oil but i have not drained it or checked it yet... i dont know which screws to undo...

Re: 1956 Johnson Javelin Water flow question

The drain screw is under the nose of the gearcase housing and fill screw is on the starboard side. They both have a flat head and use a regular slotted screwdriver. DO NOT unscrew the phillips head screw at the bottom.

Re: 1956 Johnson Javelin Water flow question

OK i changed the lower unit oil....... now i just need to know what all i need besides the fule pump to do the single line conversion...

Re: 1956 Johnson Javelin Water flow question

this might help. It is for a 5.5 but you to the conversion the same way. http://www.outboard-boat-motor-repair.com/Johnson/Pressureized Fuel Tanks.htm

The pump number I gave you will not work for this method. You will need to get a Minkuni pump you can get those at www.aircraftspruce.com

Re: 1956 Johnson Javelin Water flow question

$750 for that motor seems exceptionally high to me. I have one in the basement he can have for that price.

Anyway, that motor WAS electric start. That's what the "E" in the model number means. The "J" means Javelin. The choke solenoid is the only round thing attached to your carb that resembles a battery. It should have a wire connected to it, but since the electric start was removed they probably disconnected the wire. Either way, it does nothing when the motor is operated manually. The manual choke is just a mechanical lever. Changing it to a newer 12V style is not a bad idea, though, if you intend to convert the motor to remote controls.

You definately have a Javelin cowl and identification plate. I still suspect you have a clone, though. Post some photos under the cowl when you get a chance. Also look for a silver plug on the starboard side of the engine block. It may have the model number of the motor on it. The lower units are compatible to other years, but its very strange that the lower engine cover, exhaust tower and steering bracket would have been replaced. You don't need to chage any of them to convert to tiller steering.

Re: 1956 Johnson Javelin Water flow question

Hey is this a Javelin? been sitting in dad's shed since 1976. I painted before then and as I remember it did have some chrome on it and I believe it had Javelin on the cowl. I did check the serial # some time ago and it listed as a 1956 30hp. I hope the pick attached

Hard to say from that photo, Roger, but the black instrument panel would suggest that it is.

OK i will take pics tonight after work.... I need to know exactly what this is so i can order the fuel pump to convert this thing to a single line tank ASAP...
