This document is a technical specification drawing for a marine propeller featuring detailed engineering requirements and geometric characteristics.

The propeller is a 5-bladed, right-hand design with a diameter of 1.06 inches and is manufactured from ABS Type 4 Ni-Al Bronze material with a minimum tensile strength of 85,000 PSI. The propeller must be manufactured to ISO 484 Class II tolerances and inspected and certified by the ABS Surveyor. All threads are right-handed unless otherwise specified, with tolerances for form, roughness, and static balance conforming to ISO 484 Class II standards. The finished propeller has an estimated weight of 3,380 pounds and an estimated polar moment of inertia of 10,200 lb-ft². The propeller rotates in the right-hand direction at a rated speed of 2,650 RPM.

The technical specifications include detailed geometric data tables presenting radius, pitch, rake, skew, chord, camber, maximum thickness, leading edge radius, and trailing edge thickness measurements across multiple radial stations from 0.164 to 1.000 inches. Section offset definitions are provided for the cylindrical blade section with corresponding X, YU (suction side offset), YL (pressure side offset), and TK (thickness) values across all pitch stations from 1.0 to 100.0 inches. Engineering drawings on subsequent pages illustrate the side elevation, projected outline, pitch distribution, expanded blade outline, and detailed hub configuration including blade attachment points, fairwater cap design, and lifting eye bolt placement.
