I have a U. S. Marine brand "Sailor" 5.0 cubic inch motor that looks like it needs a new impeller. There is no ID plate and the only numbers are 270 038 in the bottom front of the power head below the carb, 535163 on the inside of the panel holding the choke and stop button, and 494032-2 on the motor mount. The motor looks like 1980's FORCE styling and has a long-shaft. Does anyone know a source of parts particularly impellers? Any other information would be greatly appreciated.
