Before & After Transformations

Auston M.
Okean 57 Sport
2023

Auston's had about everything ne needed, but it needed a little upgrade.

We upgraded the Fusion 770 headunit to the new 800 model.

We reprogrammed his CZONE digital switching to do a few custom things

We also added an automated in floor misting system on the rear of the boat, helping keep the deck flooring cool.

Finally, we upgraded all of his software to the newest versions available.

Rick T.
Sea Ray 34 Sundancer
2004

We upgraded the stereo from an older Clarion system to a Garmin/Fusion system. We also removed the older Mercury System View black and white screen, upgrading Rick to have a full color display with all of the engine data right there in the dash.

The Stereo and the Garmin MFDs all talk on the same network, so he has full color display of maps, stereo and engine data.

Rodney D.
Sea Ray 340 Sundancer
2004

Rodney came to us with the same request as most people.... "How can I get RID of this old and nasty Mercury System View???"

Ask and you shall receive!

We removed the System View screen, upgraded the wiring in his boat and built a new custom burlwood panel to match the rest of his dash.
We added a Garmin 8212 MFD, giving him full engine data as well as lake maps, stereo integration, etc.

Finally, we verified that he had the newest Garmin and system software on all of his components!

Our Services

Garmin & Fusion Software Updates
$250+ 1
This service takes about an hour. First, we confirm what devices you already have, along with what your current firmware version is. Then we will download and update and components on your vessel that can be upgraded
Garmin GPSMap MFD Installation
$4000+ 5
This service can be very complex, depending on what features you request. The Garmin MFD units are expensive and can really add to the cost of your project. We will also need to cut existing OR build custom new dash panels for the MFD. This system will require discussion about all of your wants and needs for your boat.
Mercury / Cummins Engine Data Integration
$2000 3
Wouldn't it be great to get all of your engine data, gauges and warnings on a nice color screen, rather than old style gauges or even worse, the old black and white system view screens? We can change your wiring in the boat and bring you to the new age!
