My boat had a merc 470 package.
Now It has AQ131d/SP package.
The installer did a very good job on the wiring the VP to the old Glasply dash.
Here's were I'm scratching my head. The Tilt Trim Gear assembly is shot. Motor seams OK
So i look at ebay to see what one is going for.
The used TT assemblies have these Black Boxes on Top of them
I dont have that BB. Do I need it? whats it for?
