Electric boat and vehicle conversions, made in Christchurch

Keep your ride.
Lose the petrol.

Estroke Marine converts the family boats New Zealanders already own to quiet, zero-emission electric drive. Engineered in Christchurch, proven on southern lakes.

Why convert?

The boat you love, without the fumes.

Most 3 to 6 m trailer boats still run petrol outboards, and older 2-strokes are among the most polluting motors in the country. A new electric boat with watersports performance costs far more than most families can justify. So we convert the boat you already love instead.

No fuelCharge at home or the bach from a standard supply.
Less maintenanceNo spark plugs or winterising, and no oil or fuel pollution.
Quiet waterHear the lake, not the motor. Better for wildlife and neighbours too.
