Hastrup, H

A long-tail shaft drive utilized in a propulsion system for small boats is described. The objectives of the grant are discussed. The performance of the long-tail shaft indicates a savings of approximately 50% of the fuel used by the conventional outboard motor with comparable horsepower. A summary of actions taken in regard to the reversible pitch propeller, propeller shrouds, and the tail shaft are presented. Eight test procedures are briefly outlined. Information on materials and manufacturing was sought and applied to the experimental work. Patent, manufacturing, and marketing considerations are noted. Conclusions and recommendations are summarized. (MCW)
