I read in an other thread you said "i think 95% of forward motion comes from the impellor's forward pull" forgive me if i didn't get the exact words right. Could you please explain this a little more because i always thought that the forward motion came from the thrust of the jet stream, and i don't understand how the biting edge of the impellor could pull the boat along like that. So in theory could i just take off the bowl and nozzle off and run 95% efficient? I'am really confused about this so any help would be appreciated. (qutoed from "engine + jet = loss" thread page two)
