Re: 1962 merc500
The only "tube" under the fuel pumps that i can "picture" is the one that goes to the bayonet connection, which you plug your external fuel tank into. There is the wireing harness which you connect your controller to.
There is also a tube which runs from the distibutor housing and connects just under the front cowl cover.
The engine will not run, or will not run properly if the stator is broken, however its a simple ohm's test to check if it is ok. If you have a Digital volt meter, you can easily test if it is ok. There should be a ristance reading between the two yellow wires. Make sure one at least is disconnected from the regulator. The reading varies between stators, and I don't know the correct value for yours. There should be infinate resistance between either of the wires, and the engine "block" or ground.
As for the fuel lines, if they are leaking or broken, they need to be replaced, I think you can buy ones for your engine. Otherwise you will need to buy fittings and fuel line hose, and connectors to make up your own.
The 1965 and prior sevice manual can be bought in book forum, or on a CD.
The Cd is avaliable on E-bay. I am not sure which book the site sells.
If the engine has sat for ten years, there is thread listed in the FAQ's (I think its in that section) about how to "wake an old outboard" you should read, before you try anything else to this motor.
well i just fixed my rope starter and well saw some dried up goo that dripped long time ago from the flywheel is that the coils cause looks like they need replacing anyways i was looking where to change the gear oil i found one screw( i thinks its the top) yet i cant find the other screw help? and when i fixed my rope started its really!! hard to pulll is this normal or is it that i havent ran in like 10 years so like no oil in crankcase pistons etc. the flywheel has a belt attacked to it and its attacked to something else what is that thing kinda long as the block it self and theres a rubber tube covered in string( guess to protect the tube) and its on the left side right below the fuel pump what its that? i acidently broke that the rubber was all dried up and the fuel lines how hard is it to replace them all of them from fuel pump to carbs and from fuel pump to connector to fuel line from fuel tank? where can i get those
