Outboard marine drives having splash plate
An outboard marine drive has a supporting frame, a lower unit suspended from the supporting frame, the lower unit supporting a propulsor for propelling the outboard marine drive in water, a top cowl on the supporting frame, wherein a gap is defined between a lower end portion of the top cowl and the supporting frame or the lower unit, and a splash plate on the lower unit, the splash plate being configured to reduce inflow of water to the top cowl via the gap.
1 . An outboard marine drive comprising:
a supporting frame;
a lower unit suspended from the supporting frame and configured to support a propulsor;
a top cowl on the supporting frame, wherein a gap is defined between a lower end portion of the top cowl and the supporting frame or the lower unit; and
a splash plate configured to reduce flow of water into the gap, the splash plate including an elongated flexible member having a curved shape that is deformable during installation of the splash plate onto an outer surface of the lower unit, the elongated flexible member tending to return to said curved shape after said installation to facilitate retention of the splash plate on the lower unit,
wherein the elongated flexible member has opposing ends that are fastened together to clamp the splash plate to the lower unit.
2 . The outboard marine drive according to claim 1 , the splash plate including a flange radially outwardly extending from the lower unit.
3 . The outboard marine drive according to claim 2 , the flange including a radially lower surface having an outer perimeter that is completely flat.
4 . The outboard marine drive according to claim 2 , the flange having a width that is larger than a width of the gap.
5 . The outboard marine drive according to claim 4 , wherein the width of the flange is greater along a forward side of the lower unit than along a rearward side of the lower unit.
6 . The outboard marine drive according to claim 1 , wherein the splash plate is located between the top cowl and a torpedo housing of the outboard marine drive.
7 . The outboard marine drive according to claim 1 , wherein the splash plate is located between the top cowl and an anti-cavitation plate of the outboard marine drive.
8 . The outboard marine drive according to claim 1 , wherein the splash plate is clamped to the lower unit by only one fastener.
9 . The outboard marine drive according to claim 8 , wherein said one fastener is located along a rear side of the lower unit.
10 . The outboard marine drive according to claim 1 , wherein the lower unit has an outer profile having a tear-drop shape with a wider width at a forward side of the lower unit and a relatively narrower width at a rearward side of the lower unit, and wherein the curved shape of the elongated flexible member is a corresponding tear-drop shape.
11 . The outboard marine drive according to claim 1 , wherein the splash plate is clamped to the lower unit by only one fastener fastening the opposing ends together.
12 . The outboard marine drive according to claim 11 , wherein the fastener laterally extends into the opposing ends.
13 . The outboard marine drive according to claim 1 , wherein the splash plate includes a collar and a flange that radially outwardly extends from the collar.
14 . An outboard marine drive comprising:
a supporting frame;
a lower unit suspended from the supporting frame and configured to support a propulsor;
a top cowl on the supporting frame, wherein a gap is defined between a lower end portion of the top cowl and the supporting frame or the lower unit; and
a splash plate on the lower unit, the splash plate being configured to reduce flow of water into the gap, wherein the splash plate includes a collar and a flange that radially outwardly extends from the collar, the flange being located between the top cowl and the collar.
15 . An outboard marine drive comprising:
a supporting frame;
a lower unit suspended from the supporting frame and configured to support a propulsor;
a top cowl on the supporting frame, wherein a gap is defined between a lower end portion of the top cowl and the supporting frame or the lower unit;
a splash plate on the lower unit, the splash plate being configured to reduce inflow of water into the gap, the splash plate including a collar and a flange that radially outwardly extends from the collar; and
pressure sensitive adhesive tape adhering an inner surface of the collar to an outer surface of the lower unit.
16 . A splash plate for an outboard marine drive, the splash plate comprising:
an elongated flexible member having opposing ends and a curved shape, wherein the elongated flexible member is deformable during installation on an outer surface of a lower unit of the outboard marine drive;
wherein the elongated flexible member tends to return to said curved shape after said installation and facilitate retention of the splash plate on the lower unit; and
wherein the splash plate is configured to be clamped to the lower unit by a fastener fastening the opposing ends together.
17 . The splash plate according to claim 16 , wherein the fastener is the only fastener fastening the opposing ends together.
