Less noise, more thrust!
This propeller can upgrade older 4-blade Side-Power SE30, SE40, SM30S2i, SM40S2i, SP30S2i and SP40S2i with 125mm tunnel thrusters
to the newer, quieter and higher thrust 5-blade "Q-prop".
These carefully engineered 5-blade "skew" (curved edge) propellers typically achieve a "real world" noise reduction of 20 - 40%.
Note &ndash' SP thrusters produced after 1998 have 4-blade props secured with a locknut.
Older (pre-1999) thruster models with props secured by a set-screw cannot be upgraded.)
