Disclosed herein is a switch for turning on/off the connection between a first terminal and a second terminal. The switch includes a first transistor circuit configured from two transistors connected in series between the first terminal and the second terminal; and a second transistor circuit having a gate terminal connected to source terminals of the two transistors and a source terminal connected to gate terminals of the two transistors. The connection between the first terminal and the second terminal is changed over between on and off states by changing over a potential to the source terminal of the second transistor circuit between high and low levels.

An outboard motor includes a cooling water passage that guides cooling water to cool an exhaust passage and a cylinder unit. A cooling water intake port draws external cooling water into the cooling water passage. A water pump draws cooling water into the cooling water intake port and supplies the cooling water to the cooling water passage. A thermostat is arranged in the cooling water passage downstream of the catalytic converter and the cylinder unit. A first bypass passage is connected to a first connecting section provided on the cooling water passage. The first connecting section is provided along the cooling water passage at a position farther downstream than the catalytic converter and farther upstream than the thermostat.
