Q-Prop 5-Blade Propeller Upgrade Kit for 55S Thrusters

Less noise, more thrust!
This is a complete kit to upgrade your older 4-blade Side-Power single prop 55S thruster to the new quieter and higher thrust 5-blade "Q-prop".
These carefully engineered "skew" (curved edge) blade propellers can be used on all 55S thrusters produced after 1998. See the Product Brochure reference link for more details.

5-blade Q-Props typically achieve a "real world" noise reduction of 20 - 40%.
Q-prop Upgrade Kits are available for most "SP" Series thrusters. (Note &ndash' 55S thrusters have 4-blade props secured with a locknut. Older (pre-1999) thruster models with props secured by a set-screw cannot be upgraded to a Q-Prop.)

• Q-Prop (1)
• Prop adapter (1)
