Q-Prop 5-Blade Propeller Upgrade Kit for SP155TC and SP200 Thrusters

Less noise, more thrust!
This is a complete kit to upgrade your older 4-blade Side-Power twin prop SP 155TC or SP 200 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 SP 155TC and SP 200 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' SP 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.)
