i swapped the 12/17 cutback mag and tbm out of my superjet and put it in the blaster. stock blaster.... just has a ride plate, intake grate and k&n flame arrestor.
it really loaded the motor up a lot, but its great in the chop on the way up to a wave in the surf. you can just hold the throttle WFO... no cavitation whatsoever.
as for flatwater i dunno... seems like the flatwater guys dont favor it, but as a surf guy i think its great. works good for running buoys too... no cavitation coming out of the corners ever. the place i notice it most is in washing machine conditions in the surf where it is hard to gain speed on the way to a wave. it is also good on the recovery after landing a big jump where the ski goes deep into the water.
as for removal, i only used loctite and it came right apart after one season of use. i did have small barnacles that grew under the pump cone on the stator section of my superjet. when i buy another and put it back on the superjet ill probably silicone this time.
good luck
