PROPULSION “… it is bulletproof, the design is simple, the marinization is fantastic.
It’s not an afterthought, as it might be with other engine brands. The displacement is the perfect size – we have 13 and 16 liter displacement.
The power to weight ratio is phenomenal. The torque helps the guys get out of the water quickly and they are very, very fuel ef? cient.” – Alberto Alcalá, Scania’s Sales
