Sierra Marine Knock Sensors

Not Yet Reviewed

Sierra Marine offers knock sensors for a variety of watercraft applications. A faulty original may not let the engine accelerate properly. These units retard the timing when they sense detonation, saving the engine from damage from an ignition system that is too far advanced. The knock sensors are OEM direct-fit replacements. Simply match up your original part number—and restore the powersports performance you expect.
