Abstract

Abstract An improved outer cowling arrangement for the power head of an outboard motor in which both the tray and top housing are formed from a synthetic resin for improving silencing. To insure a good fit and sealing, a supporting member and retaining member are affixed to each other and the supporting member is carried by one of the portions. Releasable latching means are carried by the other portion to engage the retainer member for holding the cowling portions together. The top housing has an inclined forward face in which a panel is positioned for passing the starting handle and starting rope. A guide defines a path of movement for the starting rope that is perpendicular to this inclined surface so that the motor can easily be started from a higher level, for example, when used as an auxiliary power source for a sailboat.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 215 words
In an outboard motor construction for use when the motor is suspended from an associated watercraft at a level below an operator in the watercraft, said outboard motor having a power head containing an internal combustion engine and a surrounding outer cowling and a drive shaft housing depending from said power head, clamping bracket means positioned beneath said power head for affixing said outboard motor to an outrigger of an associated watercraft so that said power head lies below the upper end ge of the transom of the watercraft, the improvement comprising said outer cowling having an inclined portion formed from a separate piece of cowling and extending upwardly and rearwardly to form a face that may be seen by the operator from above, and an opening herein, a recoil starter for said engine located within said cowling a starter handle accessible from said inclined portion and connected to one end of a starter rope extending through said opening, and said starter rope being connected at its other end to said recoil starter, and guide means for said starter rope for defining a path of movement of the starter rope that is perpendicular to the included portion of the cowling and generally in line with the operator and angularly disposed to said drive shaft housing.
Claim 2
Dependent Claim 215 words
In an outboard motor construction for use when the motor is suspended from an associated watercraft at a level below an operator in the watercraft, said outboard motor having a power head containing an internal combustion engine and a surrounding outer cowling and a drive shaft housing depending from said power head, clamping bracket means positioned beneath said power head for affixing said outboard motor to an outrigger of an associated watercraft so that said power head lies below the upper end ge of the transom of the watercraft, the improvement comprising said outer cowling having an inclined portion formed from a separate piece of cowling and extending upwardly and rearwardly to form a face that may be seen by the operator from above, and an opening herein, a recoil starter for said engine located within said cowling a starter handle accessible from said inclined portion and connected to one end of a starter rope extending through said opening, and said starter rope being connected at its other end to said recoil starter, and guide means for said starter rope for defining a path of movement of the starter rope that is perpendicular to the included portion of the cowling and generally in line with the operator and angularly disposed to said drive shaft housing.
