Installation of Electric Outboard Motors for Tenders
Enhance your tender’s performance with quiet, clean, and responsive electric propulsion. Our specialists design, install, and maintain complete electric outboard systems that integrate seamlessly with your yacht’s power and monitoring infrastructure.
Why Go Electric
Eco‑friendly operation
• Zero local emissions and minimal wake/footprint
• Helps meet marina and protected‑area regulations
Ultra‑quiet, low‑vibration rides
• Discreet entries to marinas and anchorages
• Smooth running for guests and crew
Lower running costs
• Electricity instead of gasoline/diesel
• Fewer moving parts → reduced maintenance
Instant power & precise control
• Immediate torque for planing and tight maneuvers
• Fine throttle mapping and selectable power modes

What We Deliver
Turnkey system design tailored to tender size, displacement, and duty cycle
Premium components from marine‑grade brands (motors, batteries, BMS, chargers)
Professional installation with corrosion‑proof hardware and clean cable routing
Smart integration with onboard AC/DC, shore power, genset, and monitoring
Sea trials & calibration including throttle response, power limits, and alerts
Crew handover & docs (ops guide, maintenance plan, wiring diagrams)
Typical System Options
Motor Power (equivalent HP / kW)
• 6–10 HP (4–7 kW): lightweight tenders, short hops
• 15–25 HP (11–18 kW): guest transfer, light loads
• 30–50 HP (22–37 kW): heavier RIBs, choppy waters
Battery Architecture
• 24/48/72 V lithium packs, IP67 enclosures
• 5–20 kWh modular capacity (expandable)
• Marine BMS with cell balancing and thermal protection
Charging Pathways
• Shore power AC chargers (fast & overnight profiles)

Installation Workflow
Survey & Planning
• Measure hull, weight, transom rating, and use profile

Component Sourcing
• Electric outboard, lithium batteries, BMS, AC/DC chargers
• Marine‑grade breakers, cabling, glands, and mounts
Mounting & Electrical
• Custom transom bracketry, strain‑relieved looms

• Battery health checks and service intervals
Typical lead time: 3–7 working days onboard (subject to scope and parts availability).
Problems We Solve
• Range anxiety → right‑sized kWh and accurate SOC/range displays
• Underpowered setups → correct kW/prop selection for load and sea state
• Messy installs → balanced weight, tidy wiring, and IP‑rated terminations
• Slow/limited charging → multi‑source charging (AC, DC‑DC, solar, genset)
Safety, Compliance & Documentation
• IP67‑rated enclosures, anti‑spark connectors, fused distribution
• ABYC/ISO wiring practices and strain relief
• CE/UKCA compliant components where applicable
• Thermal management and emergency cutoffs
• Full as‑built drawings and service schedule
Maintenance at a Glance
• Quarterly battery health check and BMS log review
• Annual inspection of seals, mounts, and harnesses
• Firmware updates for motor controller/BMS
• Off‑season storage profile (state‑of‑charge & temperature)
What We Need From You
• Tender make/model, LOA/beam/displacement
• Typical passenger/load profile
• Desired cruise speed, max speed, and minimum range
• Available charging windows (at berth/at anchor/underway)
FAQs
How far can I go on a charge?
Range depends on hull, speed, load, and kWh. As a rule of thumb, doubling speed can more than double consumption. We size the pack to your real routes and add 20–30% reserve.
How long does charging take?
From 20%→80% typically 1–3 hours with a high‑power shore charger; slower via DC‑DC while underway. We balance fast charging with battery longevity.
Is it lighter than petrol?
Motors are lighter, batteries add weight. We optimize placement and capacity to keep trim and planing behavior where you want it.
What about maintenance?
Far fewer service items than ICE: periodic software updates, anodes, seals, and routine inspections.
Can I keep my existing tender?
Yes. Most RIBs and hard tenders convert well; we confirm transom rating and balance during the survey.

Upgrading to high-efficiency solar panels is a smart choice for yacht owners aiming to reduce fuel consumption, operational costs, and environmental impact. Modern solar panels provide greater energy output, even in low-light conditions, ensuring reliable power for navigation systems, onboard electronics, and HVAC systems.
Replacing outdated hull materials with carbon fiber significantly improves a yacht’s speed, fuel efficiency, and durability. Carbon fiber offers a superior strength-to-weight ratio compared to traditional materials like fiberglass and aluminum, making it the preferred choice for modern yacht construction and retrofitting.
