I just repowered to this motor. The tattle stream was good and strong on the ear muffs, got to the lake for a test drive. Fired up the motor and the pee stream was there but kind of weak. got better with some RPMs

So today I got a new impeller, put it in and went back to the lake. Fired up the motor and the pee stream was slightly better than before, still not what I was use to compared to my previous motors. when I got the rpms up in the 1200-1800 the stream was nice and strong.

Is this normal to have a semi weak stream at idle with these motors my idle is like 750rpm? The stream is there but not solid like I would like, but it is defiantly pumping water.

thanks
