Lewmar has discontinued its legacy Horizon, Sprint, Anchorman, and Concept windlass lines (most retired between 2003 and 2006), and every obsolete model has a recommended modern replacement — typically the V700, a V1–V6 vertical windlass, the H2/H3 horizontal range, or a Pro-Series unit. Use the serial-prefix guide below to identify the windlass on your boat and find the current Lewmar model that fits in its place.

How do I identify my obsolete Lewmar windlass?
The fastest way to confirm which legacy unit you own is the serial-number prefix stamped on the windlass — each model carries its own prefix (for example, a Horizon 400 starts with 528, a Sprint 1500 gypsy/drum with 615). Many of these designs trace back to Simpson Lawrence and continued under the Lewmar name, so the branding on the deck unit alone is not always conclusive. Note the gypsy style too: gypsy-only versus gypsy/drum, and plastic versus metal gypsy, all affect which modern unit drops in most cleanly.
If the serial plate is corroded or missing, photos of the deck unit, below-deck motor, and mounting pattern are usually enough for MAURIPRO's technical team to confirm the model for you.
What replaces the Lewmar Horizon series?
The Horizon range was discontinued around 2006 (Horizon Express around 2003). Recommended upgrades:
- Horizon 400 (serial prefix 528) / Horizon 500 (529) — Horizon 400 introduced 1999; closest direct replacement: Pro-Sport.

- Horizon 1000 (531/532) / Horizon 1500 (533/534) — metal gypsy; closest replacement: H2 (serial prefix 520).
- Horizon Express (536) — gypsy only, discontinued around 2003; closest replacement: H3 (serial prefix 530).
What replaces the Sprint and Anchorman series?
The vertical Sprint line maps almost model-for-model onto today's V-Series:
- Sprint 400 / Sprint 500 — Sprint 400 introduced 1999, Sprint 500 from 1998; plastic gypsy on the 400, plastic or metal on the 500, gypsy only; closest replacement: V700.

- Sprint 1000 (609-GD / 610-GO) — metal gypsy, vertical motor, spur gearbox; closest replacement: V1 (gypsy only).
- Sprint 1500 (615-GD / 616-GO) — gypsy and gypsy/drum, vertical motor, spur gearbox; closest replacement: V2.
- Sprint 3000 (630-GD / 631-GO; Sprint 3000A 632) — vertical series-wound motor, spur gearbox; closest replacement: V4.

What replaces the Concept and Simpson Lawrence Series windlasses?
- Concept 0 — closest replacement: V700; the new mounting hole for the V700 takes up all the existing installation holes.
- Concept 1 — the deck unit can be swapped for a CPX 2 deck unit with the same hole pattern and shaft hole; 3-wire motor; closest full replacement: V2.
- Concept 2 — 3-wire motor after 1999, 2-wire before; a V4 only requires new wiring, while a V3 requires changing the deck unit; closest replacements: V3/V4.
- Concept 3 — 4-wire motor; closest replacement: V4 (the V700 is also referenced for some configurations).
- Series 300 — gypsy and gypsy/drum; closest replacement: V3.

- Series 4000 — gypsy/drum; closest replacement: V4.
- Series 5000 — gypsy/drum; closest replacement: V6.
Should I keep repairing an obsolete windlass or upgrade?
Even if an old windlass still runs, parts for discontinued units are increasingly hard to source, while modern Lewmar windlasses have service kits, switches, and motors readily available. Upgrading also brings sealed, more corrosion-resistant motors built for higher duty cycles, gypsies that grip rope and chain more effectively to prevent slippage, smoother and safer anchor retrieval in rough weather, and a reliability upgrade that adds real value when you sell the boat.
MAURIPRO's technical team supports the swap end to end: confirming your current model, comparing specs between old and new units, suggesting the correct Pro-Series, ProFish, or V-Series replacement, verifying hole patterns and deck compatibility, ensuring your chain and rode match the new gypsy, and recommending accessories like switches, breakers, and solenoids. Send photos, model numbers, or mounting details and we will walk you through it step by step.
Frequently asked questions
What is the replacement for the Lewmar Horizon 600 or 900?
The closest direct replacements are the Lewmar Pro-Series 700 and 1000, which cover both the gypsy-only and gypsy/drum versions.
What replaces the Lewmar Sprint 1500?
The Lewmar V2 vertical windlass is the closest direct replacement for the Sprint 1500 in both gypsy and gypsy/drum configurations.
Can I upgrade a Lewmar Concept 1 without drilling new deck holes?
Yes — the Concept 1 deck unit can be replaced with a CPX 2 deck unit, which shares the same hole pattern and shaft hole.
How do I know when my Lewmar windlass was discontinued?
Check the serial-number prefix against the model lists above; most Horizon models were discontinued around 2006 and the Horizon Express around 2003.
Are spare parts still available for obsolete Lewmar windlasses?
Support for discontinued units is limited, which is a key reason to upgrade — current V-Series, H-Series, and Pro-Series windlasses have gypsy kits, seal kits, motors, and controls readily available.
Will my existing chain and rode work with a new windlass?
Not automatically — the new gypsy must match your chain size and rope diameter, so verify the combination (or ask MAURIPRO to check it) before ordering.
