Yacht Refit Planning: The Spare Parts Checklist Before the Yard Period
A yacht refit runs on parts, not on goodwill. This checklist covers the spare parts to source before the yard period starts, so the refit finishes on schedule instead of waiting on a shipment.
A yacht refit is planned in months and decided in days — the days when a part is missing and the yard slot keeps billing. Most refit delays are not caused by the work itself but by parts that were ordered too late, in the wrong revision, or not at all. This checklist covers what to source before the yard period starts.
Start with the service schedule, not the breakdown list
Every piece of equipment on board has a service interval. The refit is the moment to reset those clocks, which means the parts list starts with the maintenance manuals, not with what broke last season.
Pull the service schedule for:
- Main engines and generators: filters, impellers, belts, injectors, seals
- Watermakers: membranes, high-pressure pump seals, pre-filters
- Stabilizers: hydraulic seals, bearings, servo valves
- Air conditioning and chillers: compressors, contactors, sensors
- Pumps throughout the boat: mechanical seals, impellers, gaskets
If a component is due within the coming season, service it during the refit. Doing it alongside the yard work is always cheaper than a flying technician in August.
Order long-lead items first
Some parts are shelf items. Others are made to order, and their lead times decide the refit schedule:
- Injectors, turbocharger cartridges and cylinder-head components for specific engine revisions
- Stabilizer fins, shafts and hydraulic power unit components
- Watermaker membranes and pressure vessels in non-standard sizes
- Obsolete or superseded parts that need to be traced through the manufacturer network
Identify these in the first week of planning. A part with a ten-week lead time ordered in week six is a delayed relaunch.
Verify part numbers against the actual unit
The manual says one thing; the installed unit may say another. Equipment gets replaced, upgraded and modified over a yacht''s life, and the documentation does not always follow.
Before ordering, check the type plate on the physical unit: manufacturer, model, serial number and revision. A photo of the type plate is worth more than a line in a spreadsheet. This single habit prevents the most expensive refit mistake: a pallet of parts that fit the manual but not the boat.
Build the on-board spares kit while you are at it
The refit is also the moment to stock the spares that should live on board during the season:
- A full set of filters and impellers for every engine and generator
- Watermaker consumables: pre-filters, O-rings, a spare high-pressure seal kit
- Belts, fuses, contactors and the sensors that fail without warning
- Anodes for every underwater fitting
The cost of this kit is a fraction of one emergency call-out. We covered the arithmetic in The Real Cost of a Broken Part in Peak Season.
Work with one point of contact
A refit parts list typically spans ten to twenty manufacturers. Chasing each one separately means twenty quotations, twenty lead times and twenty shipping arrangements — and nobody who owns the whole picture.
A procurement partner consolidates this: one request in, verified part numbers, quotations side by side, and one consolidated delivery to the yard. That is what we do at Premium Yacht Supply — see how it works on our yacht spare parts page: yacht spare parts service
The short version
- Start from the service schedule, not the breakdown list
- Order long-lead and obsolete parts first
- Verify every part number against the type plate on the unit
- Stock the season''s on-board spares during the refit
- Consolidate sourcing through one point of contact
