SONIC PROPULSION SYSTEMS, STERNDRIVES & SAILDRIVES

Sillette-Sonic was founded in 1975 producing the Sonic 100 sterndrive. This model is still in production in almost its original form. Now however, it is joined by many variations of propulsion system under the banner of "sonic" and "hydrodrive".

SONIC100 (the original)
	Has forward neutral reverse gearbox 1.6:1 or 2:1 ratio inbuilt, couples to engine flywheel, input torque 15kg/mtr max. CLICK HERE FOR LARGER VIEW
