Has anyone added a tilt trim gauage to a 90's model Merc?
My 89 sport 20 has a 94 200hp black max offshore Merc, everthing I have found said I need a sending unit. can't seem to locate one online, but ebay has OMC sending unit which I thought I could just mount it to the motor bracket as long as the lever moves with the bracket that tilts the motor.
any suggestions?

that motor should have a sending unit on it. It's mounted on the pin that holds the top end of the tilt cylinder in place. It has a brown and white wire comming from it routed into the cowl. it should be laying there by the main engine harness.

Cool I do have one single brown wire running to that point, so that must be it.
Do you know will I need any special trim gauage or will any I find work?

thanks I'll check it out. I am redoing my dash and I want to add a trim gauge and temp gauge, from what I have read I can just tap off the wire going to the temp horn in the dash, do you know?

takes a different sender for temp, the alarm is an on/off type sender(actually a switch), where as a temp gauge sender is a variable resistance sender to actuate the gauge. I personally don't worry about a temp gauge, I'd use a tach, fual gauge, volt gauge and a water pressure gauge if it were mine(thats what I intend to put in my boat), make sure your temp alarm is working

on your motor one of the temp switches also is a sender. I think it is in the port head. Check the cylinder heads. between the spark plugs there will be a sensor with wires comming out of it. there is one on each head. The one with one wire(tan/blue) is the overheat switch. The sensor with a few wires(tan,tan/blue,black)is the temp sender. There should be a connector for it by your main engine harness.

Ok this is what I see, on the left side looking at the back of the engine is a solid tan wire that hooks to the harnes plug that goes to the gauges. right side is the tan with blue stripe that goes to a terminal block then goes in to the wraped motor wires looks like it changes into a blue with black stripe
So is it the solid tan wire that is the sending temp wire? You guys are awsom thats for all the input.
