We fix, wire, mount, and install. Boats first — that's the day job — but the same hands do your stereo, your truck, and the thing on the dock that's been bothering you since spring.

Legend

Four symbols,
one phone number

Most shops make you pick a lane. We'd rather you called one person and got it handled — whether it floats, drives, or just needs to work again.

Marine service

Electrical, electronics, and mechanical work on power and sail. Diagnostics that start with a meter and a wiring diagram, not a parts cannon. We come to the slip, the lift, or the yard.

  • DC systems, batteries, charging & shore power
  • Nav electronics, networks, and instrument calibration
  • Engine data conversion — J1939, J1708, or analog to NMEA 2000
  • Pumps, blowers, lighting, and helm controls
  • Troubleshooting the gremlin nobody else could find

Audio installs

Head units, amps, subs, and speakers — in boats, in cars, and in the garage you actually spend time in. Clean runs, fused properly, no rattles, no whine.

Automotive

Electrical faults, accessory wiring, lighting, trailer connections, gauges, and general keep-it-running work. Same diagnostic habits, different vehicle.

Obstructions

The odd jobs. Mounts fabricated, brackets welded up, gear hauled, wiring cleaned up, the dock light that's been out for a year. Ask — the answer is usually yes.

Scale

Twelve feet
or a hundred

Drag the slider. The same shop wires the skiff on the trailer and the motoryacht on the T-head — what changes is the size of the job, not who shows up.

Center console

Battery and charging work, electronics mounted under the console, and a network that fits the space.

Soundings

The work,
in detail

A short list of what comes through most often. If yours isn't here, it probably still is — call and describe it.

  • 9 Small repairs that aren't worth a shop minimum

Data acquisition

Any engine,
on your MFD

An engine built in 1988 and a plotter built last year have nothing to say to each other. We build the translator — reading whatever the engine actually puts out, and putting clean NMEA 2000 on the backbone.

● In — what the engine speaks

Analog

Resistive senders, voltage and current loops, and raw pulse signals off engines that never had a data bus at all.

240–33 Ω · 0–190 Ω · 0–5 V · 4–20 mA · thermistor · alternator W terminal & flywheel pickup

J1939

Modern electronic diesels on 250 kbit CAN — Cummins, Volvo Penta, Yanmar, John Deere, Caterpillar, MTU, Scania.

SPN/PGN decode with source-address arbitration

J1708 / J1587

The older two-wire 9600-baud bus on pre-2007 Detroit, Cummins, Cat, and Volvo. Still everywhere, rarely supported.

MID/PID decode over RS-485

Proprietary

SmartCraft, gensets, and one-off OEM buses. If it puts out a signal, it can usually be read and re-published.

◆ Conversion — what we build
  1. Signal conditioning and isolation, so bus faults stay off your electronics.
  2. Sender curve mapping — each gauge sender measured and tabled, not assumed.
  3. Pulses-per-revolution set to the engine, so tach reads true at every RPM.
  4. Unit conversion and damping, tuned so the numbers are readable in a seaway.
  5. Instance and address assignment, so twins and triples never collide.
  6. Fault codes translated into alerts your display will actually show.
  7. Logging to a local file for trend data and warranty disputes.
■ Out — NMEA 2000

Passage plan

How a job
actually goes

No mystery invoices. You'll know the price before we touch anything, and you'll know what we found when we're done.

WP 01

You call

Tell us what it's doing, or not doing. We'll say straight away whether it's something we handle.

WP 02

We look

On site where we can. Diagnosis first — guessing at parts is how bills get out of hand.

WP 03

You get a number

Written estimate with parts and hours listed. Nothing starts until you say go.

WP 04

We work

Tinned wire, proper terminations, labeled runs. Photos if it's going somewhere you can't see.

WP 05

We test

Everything gets run before we leave. You get the readings, the receipts, and a clear account of what we found.
