Running gear
verified at sea.
Engines, generators, shafts, steering and thru-hulls — diagnosed on the hard, rebuilt under supervision, and signed off on the water rather than on paper.
A rebuild that was never sea-trialled is a rebuild you're testing yourself.
Vibration at cruise, a shaft that runs warm, an alignment that was 'close enough' on the blocks — mechanical work that gets signed off in the yard has a habit of revealing itself 20 miles offshore, alone, at night. The failure mode is almost never the part that was replaced; it's the interaction nobody checked once the hull was back in the water and loaded.
Being a full-service yard means the mechanical scope doesn't end at the travel lift. Shafts get aligned with the vessel wet and settled, not just blocked. Engines get run under load. Anything we open gets verified on a sea trial before we hand it back — and if something reads wrong, the boat comes back out.
Diagnosis, overhaul, verification.
Engine service & overhaul
Scheduled service through to major overhaul on main engines — diagnosis first, so you're not paying to replace parts that weren't the problem.
Generators & auxiliary systems
Genset service, cooling and exhaust systems, mounts and vibration isolation, plus the plumbing that usually fails before the machine does.
Shafts, couplings & alignment
Shaft inspection and replacement, coupling work, cutless bearings and stern gland service, with alignment set once the vessel is wet and settled.
Propellers & running gear
Prop inspection, removal, tuning or replacement, strut and rudder bearing work, and the drivetrain checks that explain a vibration.
Steering & control systems
Hydraulic and mechanical steering, rams, hoses, autopilot integration and control linkages brought back to correct operation.
Thru-hulls, seacocks & plumbing
Thru-hull and seacock replacement, raw water systems, hoses and clamps — the quiet items that sink boats at the dock.
Four stages, diagnosis to sea trial.
Mechanical scopes are the easiest place for a yard to over-quote. We diagnose before we quote, and verify before we invoice.
Diagnosis
Symptoms reproduced and the actual cause identified before parts are ordered — with the findings and readings sent to you.
Scope & parts
A written scope with parts sourcing, lead times and cost, so you approve the work knowing what's coming and when.
Execution
Work performed under technical supervision, with photo documentation of components before they're reassembled.
Sea trial
The vessel goes out under load and the scope is verified on the water — temperature, vibration, alignment and operation — before handover.
Closer than you think. Smarter than you'd expect.
A day-sail from San Diego
60 nautical miles south. Bring the boat down in a morning; our team guides TIP permits and vessel documentation for a clean entry.
