I redid my 1988 V20 fisherman the easy way (and a little Polish ingenuity).
I removed the plastic instrument cluster form the center console, and figured out where I wanted the gauges to go. Then I cut out the plastic where the gauges were going to go (using an old steak knife and my propane torch). I used the cut out plastic to fill in where needed (again using the knife and torch).
On the upper right part of the dash, I added a push button for the horn, and on the upper left, I added a cigarette lighter socket.
When done, I sanded the unit, sprayed it flat black and covered it with that "no slip" black tape stuff that they sell at any marina.
See pictures for details.
I have not been on this site for a long time, and I forgot how to post pictures, so email me at
