Claims6
A marine propulsion unit comprising:
- a first propeller coupled with a first propeller shaft;
- a second propeller coupled with a second propeller shaft, wherein the first and second propeller shafts are concentric;
- at least one seal between the first and second propeller shafts;
- a line collector positioned between the first and second propellers for collecting line caught by the propellers, and directing the line away from the at least one seal;
- wherein the line collector comprises a directing section having a first outer diameter;
- and a collecting section joined to the directing section and having a second outer diameter that is less than the first outer diameter at a junction of the directing and collecting sections;
- wherein the directing section tapers to the second outer diameter at the junction to direct line toward the collecting section;
- and
- wherein the line collector is positioned within the first and second propellers, with a space between the first and second propellers such that the collecting section can be exposed to the marine environment during operation of the marine propulsion unit.
