The right Andersen winch service kit is the one matched to your exact winch size, type (Self-Tailing or Classic) and production version — not just the size number stamped on top — and MAURIPRO stocks the full numbered range of genuine Andersen kits to fit it.
Andersen has built stainless-steel sailboat winches for decades, and the size number alone doesn't tell you which service kit fits — a 46ST built in 1985 needs different pawls and springs than a 46ST built after 2006, even though both are stamped "46." Order the wrong kit and the pawls or springs simply won't seat correctly. This guide walks a mid-size cruiser owner through identifying an Andersen winch correctly, explains why the same size number can need different kits, and lists the genuine kit for each model so you order the right one the first time.

What information do I need before ordering an Andersen winch service kit?
Three things: the winch size stamped on the top of the drum (e.g., "46"), whether it is a Self-Tailing (ST) or Classic (plain-top) model, and roughly when it was built. Andersen has revised the internal pawl-and-spring assembly on several sizes more than once, so two winches stamped with the same size number are not guaranteed to share a service kit.
If you're not sure of the age, check the winch's original purchase or boat-build paperwork, or compare against the version notes in the table below — MAURIPRO's rigging team can also help confirm the right kit from a photo of the winch with the drum removed.
How do I tell if my winch is Self-Tailing or a Classic (plain-top)?
Look at the top of the drum: a Self-Tailing winch has a raised stripper arm and jaws above the drum that grip the tail of the line, while a Classic (plain-top) winch has a smooth, open top with no self-tailing hardware. Andersen's own model names follow this directly — a size 46 Self-Tailing winch is listed as "46ST," and the plain-top version of the same size is simply "Model 46."
This distinction matters for service kits because the ST arm assembly adds parts (and its own springs) that a Classic winch does not have, so an ST kit and a Classic kit for the same drum size are not interchangeable.
Why do two winches of the same size need different kits?
Because Andersen has redesigned the internal pawl-and-spring assembly on popular sizes like the 46ST more than once over the model's production life. As the table below shows, a 46ST built between 1982 and 1993 uses Kit 2, one built 1993–1996 uses Kit 11, a 1993–1997/2006 unit uses Kit 17, and the current v4.0 design (2006 and later) uses Kit 19 — four different kits for one size number.
The safest way to confirm which version you have is to match your winch's known purchase or boat-build year against the production windows listed on each kit, since the parts themselves (pawl shape, spring tension, circlip size) are not visually identical across versions.
Which service kit fits which Andersen winch?
The table above covers the full current range of Andersen Self-Tailing and Classic winches, from the 12ST up to the 110ST, plus the Classic Standard and Classic 90–102 lines. Each kit number and MAURIPRO SKU links straight to the exact product page, so once you've confirmed your winch's size, type and approximate age, you can order the matching kit directly.
If your winch isn't a clean match to one row — for example it falls right on a production-year boundary — MAURIPRO's rigging team can help confirm the right kit before you order, since installing the wrong pawls or springs can leave a winch slipping or grinding roughly.
What's actually inside an Andersen winch service kit?
Every numbered kit centers on the parts that wear fastest inside a winch: pawls and pawl springs, which are what let the drum turn freely one way and grip the load the other. Depending on the kit, that's supplemented with circlips, bushings and the small screws that hold the mechanism together on reassembly.
Kit 10 is the exception — a universal 20-piece pawl spring assortment sized to fit across the Andersen range, useful as a spares-locker backup rather than a model-specific rebuild kit. Kit 20, the Line Tender Kit, is a different accessory altogether and not a wear-parts kit.
Where can I buy genuine Andersen winch parts?
MAURIPRO carries the full numbered range of genuine Andersen winch service kits shown above, along with individual spare parts (disc springs, pawls, top caps and self-tailing arms) for specific models. Confirm your winch's size, type and approximate age first, then order the matching kit rather than a generic marine-grease-and-spring assortment, since fit and spring tension are model-specific.
Genuine Andersen parts are worth insisting on here: a pawl or spring that's close but not exact can seat incorrectly and cause the winch to slip or free-spin under load, which is the opposite of what a service is meant to fix.
Which should I choose?
Start with the size stamped on the drum, then decide Self-Tailing vs. Classic by looking for the stripper-arm hardware on top. For a size 46ST built before 2006, cross-check the finer production window (1982–93, 1993–96, or 1993–97/2006) against the table above rather than assuming the newest kit fits — that's the single most common ordering mistake on this model. If your winch is out of production or you can't confirm the exact version, Kit 10's universal pawl springs are a reasonable stopgap for a single sticking pawl, but a full, model-specific kit is the right call for a proper service.
Frequently asked questions
How do I find my Andersen winch's size number?
The size number is stamped on the top of the winch drum — for example "46" for a size 46. Remove the drum to check for any additional date or version marking if two kits are listed for that size.
Is a 46ST winch the same as a Model 46 Classic winch?
No. Both share the size number 46, but the 46ST has self-tailing jaws on top of the drum and the Model 46 Classic does not. They use different service kits because the ST version has extra parts the Classic version lacks.
Can I use Kit 10 on any Andersen winch?
Kit 10 is a universal 20-piece pawl spring assortment that fits across the Andersen range and works as a general spares-locker backup, but a model-specific numbered kit is the more complete and correct choice for a full service.
What if my winch doesn't match any row in the kit table?
Contact MAURIPRO's rigging team with your winch's size, type (ST or Classic) and any date or version code visible once the drum is removed, and they can confirm the correct kit before you order.
Do I need any special tools to install an Andersen service kit?
No special tools beyond what came with the winch — typically a small screwdriver or Allen key to lift the drum and access the pawls, plus a clean surface to lay out the small springs and circlips so nothing gets lost during reassembly.
