help merc 50

i have got a 81 merc 50 blueband and have found a pipe that comes out of the top of the lower unit at the front below the pivot(if you understand that well done) it looks like a breather pipe or similer, when you blow down it it vents at the front of the lower unit out of a small hole. can anyone tell me what this is and if it should be connected to anything thanks. i could email some pics if that would help. <br /> another question is it possible to fit a tachometer and if so how do i go about it mine is not electric start if that maters.<br />thanks fellas

That's where the speedometer connects to.<br /><br />There should be a pair of wires or an additional plug in your throttle cotroller or ignition switch harness for the tach.

there is only two wires to my controler i assume they are for the kill switch. so how would i connect a tach up to my motor. what do i need to connect a speedometer then just a sensor and guage if so where would i get one. cheers

That engine uses a alt. driven tach it's the gray wire that is hooked to the rectifier at the same place that the yellow wire from the stator is hooked to the rectifier

my motor is a pull start so it doesnt have a rectifier but i can see where you mean on the wiring diagram for the electric start motor
