I got the Attwood Tsunami 500 GPH pump in my ski, I like it so far, only have a few hours on it so far but you can take the entire pump apart, like you unhook it from the base, and then you can take the motor/impeller out of the case. It seems like it would come in hand in case you get it a styrofoam kernel or whatever stuck in it like I did on an old Rule pump I had one time.
