Description
Mercury Outboard Engine FourStroke 25 M EFI
Mercury FourStroke engines combine reliability, flexibility, power and efficiency.
Which boat is it for?
With 25 hp, this engine suits RIBs and boats of 4 to 5.5 metres, also with a load or several people on board. The right power depends on the hull: never exceed the maximum power on your boat's capacity plate.
What the 25 M EFI version means
- 15" shaft (381 mm): for transoms about 38 cm high. Measure your transom before choosing; ask us if in doubt.
- Manual start and tiller: the lightest, simplest setup; pull-start, no battery needed to start.
