ABSTRACT:
An exhaust timing valve control for an exhaust timing valve of an engine powering a watercraft is disclosed. The engine has an exhaust port leading from a combustion chamber for routing exhaust products therefrom, the exhaust timing valve cooperable with the exhaust port and movable between a first position for delaying the closing of said exhaust port and a second position for advancing the closing of said exhaust port. The watercraft includes a power source which provides power when the engine is started. The exhaust timing valve control includes a mechanism for turning on the control when the engine is started and the power source provides power, and for turning off the control when the engine is stopped.
