I’m pretty certain that it’s more expensive than you want to pay.
Just like the only difference in Verado’s is the computer.
The 225 and 300 are the same
motor, different computer.
But the
price of the computer will blow you away.
However not knowing what system you have I can’t comment, but there is an amazing amount of data available on the bus that can be displayed on a plotter or what was called a Merc
monitor.
For Verado specific questions, this ought to be a very good site to go to.
