Abstract: A polyamideimide resin containing a structural unit (Ia) represented by a formula shown below, and a structural unit (IIa) represented by a formula shown below. In the formula (Ia), each X independently represents a hydrogen atom, or at least one substituent selected from the group consisting of halogen atoms, alkyl groups of 1 to 9 carbon, atoms, and alkoxy groups and hydroxyalkyl groups of 1 to 9 carbon atoms. In the formula (IIa), each R independently represents a hydrogen atom, or at least one substituent selected from the group consisting of alkyl groups of 1 to 9 carbon atoms, alkoxy groups of 1 to 9 carbon atoms and halogen atoms, and n represents an integer of 1 to 6.

Abstract: An outboard motor packing structure convertible to a display stand, having a rectangular parallelepiped formed with rod members, which rod members include first side rods on both right and left sides connecting the front and back rods, in which an end of each first side rod is detached from the front rods and connected to the bottom rods when the packing structure accommodating an outboard motor therein is converted to a display stand by disjointing parts of the rods, wherein the outboard motor is in the same position as when installed in a boat.

Abstract: A cowling assembly for an outboard unit wherein a first cowling assembly defines a cavity in which the powering internal combustion engine is contained and which has a top surface, a second cowling assembly having a top surface is affixed to this first cowling assembly and interengaging portions between the two top surfaces ridigify the top surface of the second cowling assembly without adding significantly to the weight.

Abstract: Two embodiments of protective cowlings for the power head of an outboard motor that form both forwardly and rearwardly facing air inlet openings so as to insure adequate air induction to the engine. The forwardly facing air inlet opening is located so as to avoid water being able to enter into the interior of the protective cowling and into the engine induction system.
