I've only ran my boat for one weekend so far but my pump seamed like it was unloading rather easy. it seamed like if i jumped on the throttle and there was any type of small wake that i would bounce off the rev limiter, or if i was doing a 180 deg turn and got on the throttle a bit the last bit of the turn it would do the same. I noticed that when i had the boat full of heavier guys (i'm only 120-130lbs) that it didnt seam to do this. Again i only ran the boat for one weekend though and didnt get much nice water to play in. I've been wondering if i need a loader... Guess we'll see how it preforms the next trip.
