Converting your existing gas boat to electric can cost $10,000-$50,000 but saves money long-term. Here's how.
Step 1: Assess Your Boat
Weight, size, and hull type matter. Lightweight fiberglass boats convert best. Avoid heavy steel hulls.
Step 2: Choose Your System
- Direct Drive: Most efficient, replaces engine directly
- Pod Drive: Great for sailboats, compact
- Outboard: Easiest to install, portable
Step 3: Select Battery
Li-ion: 150-250 Wh/kg, 2,000+ cycles
LFP: 100-160 Wh/kg, 3,000+ cycles, cheaper
Estimated Costs
- Motor: $3,000-$15,000
- Battery: $5,000-$25,000
- Charger: $1,000-$3,000
- Installation: $2,000-$5,000
- Total: $10,000-$50,000
