Replacing flush mounted graphs

Need advice I’m replacing my flush mounted graphs console and bow with dual graphs I don’t know what to do about the openings from the flush mounted graphs 12 at console and a 9 at the bow. Also need recommendations on any dual mounts you guys are using. Phoenix 921

Bow is simple to replace with some ABS Plastic you can buy off Amazon and you can get it in various colors and thickness. Remove the old cover molding, trace it out on some wood to make a mold, cut the wood mold and sand so it's the exact shape, then take a router and route out the mold.
The Helm is a bit more complicated with all the cables, and such, but it can be done the same way. I've seen a guy on here that does it as well. Take pictures of the wiring and cables before you remove anything and disonnect the battery before you do it or you will be replacing fuses.

And then you can order new rocker switches from new wire marine.

Precision Sonar!

Just buy replacement panels from the dealer.

Get a Dual mount that inserts into the 12" mounting hole for your boat brand from one of the bigger companies. Precision and Bass Boat Technologies are both good sturdy brands! With BBT, you tell them what boat model/year and what previous/current graphs are and they customize the mount hardware for you. It's "almost" right....

The Helix hardware they sent me was the wrong size, so I bought the bolts/washers/nuts i needed for that part of the job rather than calling since I was running close to a tournament weekend.

use the abs and buy the dual mount you want, get 1/4" abs and cut to fit, mount mounts. redid my dash with it and worked excellent, redid all rocker switch panels as well.

Thanks guys for the tips!!

Since my boat is a little older I had to look a little harder but I was able to locate both the bow and the console panels. I thought about having some custom aluminum panels made as well and have them anodized either black or red; main colors of my boat, and then have them engraved with the Skeeter logo. I want to go gymbal mount at the console which I already have a Ram mount and then either a gymbal or factory mount on the deck. I'd like to be able to remove them when the boat isn't in use.

something I just remembered too is C&O marine, they have a lot of stuff like that. they may have blank factory panels for ya.

call and ask for carol the parts mom, she is good at finding what you want.
