Outboard motor
An outboard motor includes an outboard-motor main-body, an anti-ventilation plate, and a foreign-matter collection apparatus. The anti-ventilation plate is provided on the outboard-motor main-body. The foreign-matter collection apparatus is provided above the anti-ventilation plate and outside the outboard-motor main-body and located at a height such that a water intake is submerged under water when a ship to which the outboard-motor main-body has been attached is in a pre-planing state.
1. An outboard motor comprising:
an outboard-motor main-body;
an anti-ventilation plate provided on the outboard-motor main-body; and
a foreign-matter collection apparatus provided above the anti-ventilation plate and outside the outboard-motor main-body and located at a height such that a water intake is submerged under water when a ship to which the outboard-motor main-body has been attached is in a pre-planing state,
wherein the foreign-matter collection apparatus includes a water outlet and a backflow release section for reducing outflow of foreign matter by releasing a backflow flowing through the water outlet toward the water intake.
2. The outboard motor of claim 1 , wherein the foreign-matter collection apparatus further includes a first filter, a second filter including finer pores than the first filter, a first passage extending from the water intake through the first and second filters, and a second passage branched from a portion of the first passage between the water intake and the second filter.
3. The outboard motor of claim 2 , wherein the foreign-matter collection apparatus further includes a first foreign-matter removal port for removing foreign matter caught by the first filter and a second foreign-matter removal port for removing foreign matter caught by the second filter.
4. The outboard motor of claim 1 , wherein a lower edge of the water intake is provided rearward of an upper edge of the water intake with reference to the outboard motor.
5. The outboard motor of claim 1 , further comprising:
an anti-splash plate provided on the outboard-motor main-body,
wherein the water intake is located below the anti-splash plate.
6. The outboard motor of claim 1 , further comprising:
an elastic body located between the foreign-matter collection apparatus and the outboard-motor main-body.
7. An outboard motor comprising:
an outboard-motor main-body;
an anti-ventilation plate provided on the outboard-motor main-body; and
a foreign-matter collection apparatus provided above the anti-ventilation plate and outside the outboard-motor main-body and located at a height such that a water intake is submerged under water when a ship to which the outboard-motor main-body has been attached is in a pre-planing state,
wherein the foreign-matter collection apparatus includes a first filter, a second filter including finer pores than the first filter, a first passage extending from the water intake through the first and second filters, and a second passage branched from a portion of the first passage between the water intake and the second filter.
8. The outboard motor of claim 7 , wherein the foreign-matter collection apparatus further includes a first foreign-matter removal port for removing foreign matter caught by the first filter and a second foreign-matter removal port for removing foreign matter caught by the second filter.
9. The outboard motor of claim 7 , wherein a lower edge of the water intake is provided rearward of an upper edge of the water intake with reference to the outboard motor.
10. The outboard motor of claim 7 , further comprising:
an anti-splash plate provided on the outboard-motor main-body,
wherein the water intake is located below the anti-splash plate.
11. The outboard motor of claim 7 , further comprising:
an elastic body located between the foreign-matter collection apparatus and the outboard-motor main-body.
