Abstract
A marine propeller (10) has an integral aft skirt portion (30, 74) with a plurality of slots (34, 36, 38, 40, 42, 44) extending forwardly from the trailing end (32, 72) and dividing the skirt portion into a plurality of circumferentially spaced segments (46, 48, 50, 52, 54, 56) separated from each other at the trailing end by respective slots therebetween and integrally joined to each other at the outer hub (14) forwardly of the slots. Aft trailing blade tips (28e) of the propeller blades (24, 26, 28) meet the outer hub at points (60) offset from the slots to prevent engine exhaust in the through hub exhaust passage (22) from seeking the negative pressure backside surfaces (28b) of the propeller blades through the slots.
