two questions and an update lol my project is coming together nicely almost ready to head back out on the water, not bad for my first ground up resto!

now onto the questions, I purchased the teleflex red international series 6 gauge box set, my boat originally had 5 guages fuel, tach, temp, volts, and speedo. my first question is the teleflex box set has all those plus oil pressure but because my o/b takes an oil gas mix does this mean I cant use this guage? is there any other purpose it could serve? secondly are the wires coming out of the control unit from the sending units? its an older evinrude 85 horse by the way. also is there a way to put a tank on the engine and wut not to change it from taking mixed gas to seperate gas and oil? and my last question is the box set came with a pitot. when I went to install it today i realized it was backwards in that it moved freely back and forth but is upside down when you pull the plastic arm up to the right position it does not move at all whats the deal? anyone else had this problem?

Re: teleflex guages question

Can't think of a use for the oil gauge,Some speedo pitots are designed to flip up if you hit something so i think you mounted it upside down.The other gauges should be marked and fairly easy to hook up.Ignition,ground,12v,ect..
You could do away with the oil pressure and install a water pressure guage for the outboard.More info about what control you have may help on the wire question.
Hopefully you marked all the wires or are replacing one gauge at a time.

Hmmm...I always assumed a 2 stroke used and needed an oil and the Oil Pressure guage for the same reason it's so important on 4 strokes or does the gas/oil mix lube the complete engine?

Agree with Gary that your pitot is likely upside down.
I suspect that the wires coming out of the control unit you are referring to are probably sender and ground for the tach. That is what I had on my '76 135hp Evinrude. The Teleflex Sahara tach I used required a 12v switched lead as well.

Other than the lower unit, yes the gas oil mix lubes the entire engine.

Our, 2 cycle, crank and rod bearing are needle bearings and as such require LOTS less lubrication than the solid bushing used in 4 cycle car engines. I don't know if 4 cycle OB's use bushing or bearings..
