Replace the E120 display using the verified cutout adapter. Reuse each peripheral only after model-level compatibility is proven.
Best for: smallest defensible scope.Tradeoff: more legacy interfaces and less future flexibility.

This illustrative Raymarine E120 example shows equipment decisions, a manufacturer-documented adapter and the checks still needed aboard. It demonstrates the intended report structure; it is not a completed customer report.

01 · EXECUTIVE ANSWER
Modernize the display—but do not buy the rest of the system yet.
The Raymarine E120 Classic is the confirmed system anchor. The radar, autopilot and depth/sonar equipment were identified by category, but their exact models and network relationships remain unknown. Those unknowns must be documented aboard before anyone can responsibly decide what can be reused.
OWNER DECISION
Proceed with Full Modernization planning around an Axiom+ 12 direction. Hold the radar, autopilot and sonar purchasing decisions until the dockside checklist is complete.
02 · CURRENT SYSTEM DECISIONS
Known facts and unknowns stay separate.
System areaDecisionWhat it means
Existing helm openingADAPTER
The E120 Classic fixing pattern can be reused with the verified A80529 adapter.
RadarVERIFY
Exact scanner model and interconnect cable are still required.
AutopilotVERIFY
Controller, course computer, drive and steering type remain unconfirmed.
Depth / sonarVERIFY
Transducer model, frequency and connection architecture remain unconfirmed.
Three equipment categories still need exact model identification. Network connections have not been documented.
03 · THREE PLANNING PATHS
Three ways to approach the refit.
Tradeoff: more legacy interfaces and less future flexibility.
Build a current Axiom+ core, preserve proven-compatible peripherals and replace incompatible equipment selectively.
Best for: balance of capability, cost and serviceability.Tradeoff: interface decisions remain critical.
Plan toward one current-generation Raymarine architecture, then finalize the replacement scope after verification.
Best for: consistency and easier future servicing.Tradeoff: highest scope and investment.
04 · VERIFIED FINDING
A documented adapter, with installation checks still open.
MANUFACTURER-BACKED MIGRATION DETAILRaymarine A80529 adapter plateSupports installing an Axiom+ 12 using the existing C120/E120 Classic fixing holes. Final fit, access and helm condition still require onboard confirmation.
Raymarine lists A80529 for fitting an Axiom 12 or Axiom+ 12 into a C120/E120 Classic cutout. Check the installation instructions and available space before selecting it. Raymarine accessory reference (PDF).
05 · DOCKSIDE VERIFICATION LIST
The exact information the shop still needs.
- 01Radar
Photograph the model label and record the scanner-to-display cable and connector.
- 02Autopilot
Record the controller, course computer, heading sensor, drive unit and steering type.
- 03Depth / sonar
Record the transducer model, frequency, connector, mounting style and any sounder module.
- 04Network and power
Map SeaTalk, SeaTalkng/NMEA 2000, Ethernet, power feeds, interfaces and physical condition.

Installer handoffA practical verification list that turns unknowns into the information an installer needs to prepare a quote.
After the vessel checks, the qualified installer converts this planning package into the final bill of materials, labor scope, estimate and commissioning plan.
07 · PROFESSIONAL BOUNDARY
A preliminary decision brief for professional review.
This report organizes the owner’s goal, equipment evidence, planning paths and open questions. It does not replace onboard inspection, manufacturer requirements, qualified system design, final scope, estimating, installation or commissioning.
