Like the others said, use a level from the bottom of the boat to the cavitation plate and make sure when the motor is all the way down they line up.

Anyone have experience wiring a Mercury control box to console gauges?
My existing Teleflex tachometer has several posts on the back. Not sure what each one is for. My Mercury control box has a female plug for wiring a tach.
Is a wiring harness required? How do you get from the plug down to wire leads to the tach?

I was able to see the indentions from the previous motor mount so I used that for starting point. Lined up perfectly on the first try.
