Lewmar Electric Winch Conversion Kit Price: A Practical Guide (2026)

Updated November 2026

A lewmar electric winch conversion kit price depends on which kit you need, what drive and motor size it matches, and whether you plan to install it yourself or pay a shop. This guide walks through what these kits usually include, the factors that push the cost up or down, and the hidden expenses buyers often overlook. Rather than quoting numbers that change by retailer and region, it gives you a method for estimating your own total so you can compare offers accurately.

What a Lewmar Electric Winch Conversion Kit Usually Includes

People often use “conversion kit” loosely. In the anchor and deck hardware world, it generally means a package that lets you replace a manual windlass or a hand-operated capstan with an electric drive, or that adds an electric motor and control to an existing gear. Before comparing any lewmar electric winch conversion kit price, confirm exactly what is in the box. Kits from manufacturers commonly differ in the following ways:

• Motor assembly: The electric motor, sometimes with a gearbox or a direct drive arrangement, sized to a specific load rating.
• Mounting hardware: Base plates, bolts, backing plates or adapter brackets that match a particular footprint.
• Control unit: A rocker switch, remote handset or foot switch, and sometimes a circuit breaker or solenoid.
• Wiring harness: Cable of a stated gauge with lugs. Some kits include it; others expect you to supply your own.
• Drum or gypsy adapter: Needed when the new drive must fit a gypsy or drum that was originally designed for a manual handle.
• Documentation: Installation manual, load chart and warranty terms.

Manufacturers specify load ratings and duty cycles for each model, and those figures should drive your choice far more than the packaging language. A kit rated for a lighter anchor rode will not safely handle a heavier chain and rode combination.

Factors That Shape the Lewmar Electric Winch Conversion Kit Price

When you look at listings, the spread between kits usually traces back to a handful of variables. Understanding these lets you judge whether a higher or lower figure makes sense.

Load Rating and Motor Size

Higher pull capacity requires a larger motor, heavier gearing and thicker mounting components. This is the single biggest driver of cost. Check the rated working load and the stall or maximum load figure the manufacturer publishes, and match that to your intended use rather than buying the largest unit available.

Compatibility With Your Existing Gear

If your current windlass uses a particular gypsy size, drum diameter or bolt pattern, you need a kit designed for that interface. Adapters add to the total. Measure the existing base plate spacing, the shaft diameter and the gypsy profile before ordering.

Control Type

Simple rocker switches cost less than remote handsets, and waterproof sealed controllers cost more than basic ones. Remote control can be worth the difference on a bow windlass where you cannot stand at the helm while lowering anchor.

Included Wiring and Protection

Some kits ship with cable, a breaker and a solenoid. Others leave all of that to you. When two kits look similar on paper, the one that includes marine-rated cable and a properly sized breaker may be the better value even if its headline figure is higher.

Purchase Channel and Warranty

Authorized dealers may bundle installation advice, technical support or extended warranty coverage. Gray-market listings can look attractive but may lack warranty support. Read the return policy and warranty terms for each seller.

Step-by-Step: Estimating Your Total Project Cost

The kit itself is only part of the outlay. Use this sequence to build a realistic total before you commit.

1. Define the job. Note the anchor or line weight, the windlass location (bow, stern, deck or cockpit), and how often you will use it.
2. Measure the existing hardware. Record base plate hole spacing, gypsy or drum dimensions, shaft diameter and deck thickness.
3. Shortlist kits by load rating. Keep only those rated comfortably above your real working load.
4. Confirm what is included. Make a line-by-line list of motor, control, wiring, breaker, adapters and fasteners for each candidate.
5. Add missing components. Price cable, breaker, switch, terminal lugs, heat-shrink, sealant and any adapter you still need.
6. Add installation labor if outsourcing. Get a written quote that names the work included.
7. Add a contingency. Hidden issues such as corroded wiring, deck rot or an undersized battery bank are common.
8. Compare totals, not headline prices. Two offers are only comparable once both include the same parts and services.

Sample Cost Breakdown Checklist

Use this table to organize quotes side by side. Fill in your own figures from sellers rather than relying on published estimates.

Line Item	Included in Kit?	Notes to Check
Electric motor and drive	Usually yes	Confirm rated load and duty cycle
Mounting base or backing plate	Often yes	Match bolt pattern to existing windlass
Control switch or remote	Usually yes	Waterproof rating and cable length
Power cable	Sometimes	Gauge sized for run length and current
Circuit breaker or fuse	Sometimes	Rated above stall current, below cable limit
Solenoid or relay	Sometimes	Matches motor current draw
Terminal lugs and heat-shrink	Rarely	Marine-grade, tinned copper preferred
Gypsy or drum adapter	Depends on model	Required if sizes differ
Installation labor	No	Get written scope of work

Common Mistakes When Pricing a Conversion

• Buying on load rating alone. A motor that can lift the load may still overheat under real duty cycles. Check the manufacturer’s duty figures.
• Ignoring the battery and charging system. A high-draw winch on an undersized battery bank can cause voltage drop and nuisance failures. Owners often underestimate this.
• Undersizing the cable. Long runs with thin wire create heat and lost power. Calculate gauge from run length and current.
• Skipping the breaker. Fuses or breakers protect both the motor and the wiring. Omitting them is a fire risk.
• Forgetting deck reinforcement. A higher-output drive transmits more force into the deck. Check backing plates and fasteners.
• Comparing kits with different inclusions. A lower headline figure can end up costing more once you add missing parts.

Tips for Getting the Best Value

• Request written parts lists from each seller so you can compare line by line.
• Ask whether the warranty covers the motor, the control and the wiring separately.
• Buy cable and terminals from a marine supplier if the kit does not include them. Automotive-grade wire often lacks the insulation and corrosion resistance needed on a boat.
• Keep receipts and the installation manual with your records for warranty claims.
• If you are unsure about electrical work on your vessel, consult a marine electrician or a qualified installer before proceeding.

Recommended gear

Several items help a conversion go smoothly, especially if you are installing the kit yourself.

• Marine-grade tinned copper battery cable. Stranded, tinned wire resists corrosion in damp locations and holds up better than standard automotive cable. View on Amazon
• Heavy-duty crimping tool with a ratchet. A proper ratcheting crimper produces consistent crimps on large lugs, which matters for high-current connections. View on Amazon
• Adhesive-lined heat-shrink tubing. The adhesive seals out moisture around lugs and splices, which helps prevent corrosion in marine environments. View on Amazon
• Digital multimeter. A meter lets you check voltage drop under load and confirm continuity before energizing the system. View on Amazon

FAQ

Is the lewmar electric winch conversion kit price the only cost I should plan for?

No. Budget for cable, a breaker, terminals, sealant, possible deck reinforcement and, if you hire help, installation labor. Those items can add a meaningful share to the total.

How do I know which kit size I need?

Start with your anchor and rode weight plus a margin for loading, then check the manufacturer’s rated working load and duty cycle. Match the kit to the windlass footprint and gypsy or drum size you already have.

Do conversion kits usually include wiring?

It varies by model. Some include a cable harness and breaker, while others expect you to supply them. Check the parts list before comparing prices.

Can I install a conversion kit myself?

Many owners with basic mechanical and electrical skills do this work, but it requires correct wire sizing, proper fusing and sound deck mounting. If you are not confident, a qualified marine technician is the safer choice.

Why do similar-looking kits have such different totals?

Differences in motor rating, control type, included cable, adapters and warranty terms all affect the final cost. Compare inclusions line by line rather than headline figures.

Does a remote control make a big difference?

For bow windlasses, remote operation lets you control the anchor while positioned safely away from the helm. Owners often find it worth the added expense on larger boats, though a rocker switch may suffice on a small vessel.

How long should a conversion kit last?

Service life depends on load, duty cycle, maintenance and environment. Manufacturers typically publish warranty terms, and those terms are the most reliable guide to expected coverage. Rinse saltwater off the unit after use and inspect connections regularly.

Should I buy from an authorized dealer?

Authorized dealers are more likely to offer warranty support, correct parts matching and technical guidance. Verify the seller’s return policy and warranty terms before ordering.

Conclusion

The lewmar electric winch conversion kit price you see is only the starting point. Matching load rating, compatibility, control type and included wiring will determine whether a kit is a sound purchase. Build a full project total with cable, protection and labor, then compare offers on that basis. Consult a qualified marine electrician if any part of the electrical work is unfamiliar.
