ROYAL DOLPHINPublished September 29, 2026 · Royal Dolphin
The budget for an electric boat conversion is built from a complete system: propulsion, batteries, charging, accessories and installation work. The listed price of a boat motor alone is therefore not a complete conversion quotation.
Items that should be detailed in the quotation
| Item | Questions to ask |
|---|---|
| Motor and transmission | Which exact reference? Are controller, throttle, display and cables included? What mechanical adaptation is planned? |
| Batteries | Which references and quantities? What usable energy and reserve have been selected for your use? |
| Charging | Which charger and shore supply? What charging time is estimated for the proposed battery bank? |
| Accessories and integration | Which links, protection devices, cabling and supports are required? |
| Work and testing | Are removal, installation, handling and tests included? Who performs them? |
| Delivery and terms | What destination, shipping cost, confirmed lead time and warranty conditions apply? |
How should you use the prices in the Royal Dolphin catalogue?
The motor pages, battery pages and charger pages help create an initial selection. Displayed prices are indicative and must be confirmed in the quotation.
The WaterWorld configurator (FR) separates priced equipment from items quoted on request. Check quantities and every required item: an incomplete subtotal must not be treated as the final conversion cost.
Why compare quotations for the same use?
For a meaningful comparison, give each supplier the same project file: boat specifications and loaded weight, current installation, target speed, expected motor-running time and navigation area. Ask each proposal to state its range assumptions and the exact scope of work.
Also compare what can be retained and what must be replaced. A motor-only proposal and another proposal including batteries, installation and testing do not cover the same scope.
What total budget should you expect for your boat?
A reliable figure requires a precise configuration and scope. There is no universal fixed price: start with the preliminary boat study (FR) and then request a detailed quotation.
For a project in France or elsewhere in Europe, include the destination country and postcode, the boat location and your schedule. Product availability, delivery and installation arrangements must be confirmed for each project.
