Rolla propellers
Swiss-origin ROLLA submerged and surface-piercing propellers for surface drives and high-performance craft.
ROLLA propellers, now part of Twin Disc, are made in submerged and surface-piercing designs. The surface-piercing versions are matched to Arneson and other surface drives on fast yachts, patrol and racing craft. The submerged range serves conventional shaft installations. ROLLA is sold through Twin Disc's distributor network.
