Well, i got that damn rock out of my impeller today. Put new plugs in because i think i fouled them when i was trying to start it with the rock in there. Put the new plugs in and it would crank and crank and crank. Gave up for a little bit to let the starter cool down, then tried again. Finally got it to start and it idled up to about 2000ish. Tried to give it alittle gas and it died. Started it again let it idle for 10 seconds then tryed to give it gas and it dies out. Damn thing will not let me give it gas. I didnt let it run much longer after that, because it wasnt in the water or on the hose
