Marine Replacement Parts

When the boat builder is gone and the chandlery doesn't stock it — shaft components, deck hardware, seacock parts and engine room fittings in 316L, naval brass and duplex, reproduced from your corroded original.

Why Marine Parts Disappear

Boats outlive their builders. A 30-year-old yacht is entirely serviceable, but the yard that built it — and made its custom fittings — may have closed decades ago. Production hardware gets discontinued, metric replaces imperial, and the specific casting your stern gear needs is in no catalogue anywhere.

We reproduce marine parts from the original — even heavily corroded. Corrosion rarely destroys the geometry we need; the part's design intent is recoverable from what remains plus the components it mates with.

Marine Parts We Reproduce

Shaft components

Taper sleeves, shaft nuts, keys, locking collars to propulsion tolerances.

Cutlass bearing housings

Stern tube carriers with water inlet provisions, original interference fits.

Stern gland parts

Seal carriers, packing followers, lantern rings.

Deck hardware

Cleats, fairleads, stanchion bases, custom fittings in 316L.

Rudder hardware

Pintles, gudgeons, tiller heads, quadrant components.

Seacock components

Bodies, bonnets, handles in dezincification-resistant bronze.

Engine room fittings

Engine bed brackets, exhaust supports, heat exchanger end caps.

Raw-water pump parts

Impeller housings, cam plates, wear plates. See pump parts.

Material Selection — Get the Galvanic Pairing Right

ApplicationCorrect materialCommon mistake
Below waterline, bronze systemNaval brass / HTB1Ordinary brass — dezincifies in months
Deck hardware316L passivated304 — tea-stains and pits in salt spray
Against stainless prop shaftBronze with isolationAluminium — sacrificial corrosion
High-load chainplates, fittingsDuplex 2205316 in crevice conditions — pitting
Bearings & wear stripsDelrin / HDPENylon — swells when saturated

If the original corroded fast, tell us where it lived. Galvanic pairing, oxygen starvation in crevices, and stray current all destroy specific materials in specific ways. Knowing the failure pattern lets us specify a replacement that won't repeat it — usually at no extra cost.

How It Works

  • Send the part and your haul-out date — corroded, broken, fine. We work backwards from when the boat must launch.
  • Free CAD reconstruction — geometry restored to design intent, material specified for the environment. See marine RE process.
  • Machine, passivate, ship — stainless passivated post-machining, shipped tracked worldwide with inspection report.

Frequently Asked Questions

+

Yes. Custom and semi-custom boats are full of one-off fittings no catalogue stocks. Send the failed part — corroded is fine — and we reproduce it in 316L, bronze or the appropriate marine grade. No builder cooperation or drawing needed.

+

316L and 304 stainless, naval brass (HTB1), phosphor bronze, duplex 2205, super duplex 2507, plus HDPE, Delrin and PTFE for bearing and seal applications. Stainless parts are passivated after machining.

+

Tell us the date the vessel goes back in the water and we work backwards. A single machined 316L component is typically 5–10 working days after CAD approval, plus shipping. Express options exist for breakdowns — we confirm honestly what is achievable.

+

It can. We review the galvanic pairing: if a bronze part corroded against a stainless shaft, or aluminium against bronze, we suggest material or isolation changes. Often the fix is as simple as the correct grade plus an isolating washer — we advise as part of the quote.
