alright, so im i first time boat owner. i have a 91 johnson 150hp on my ranger bass boat. it starts up great with the little white idler arm up. but as soon as i put it down the engine will (bog) shut down, before i have time to get the throttle down to go anywhere. i mean if i stage it right i can push it down and push it forward at the same time but then the engine gives a kick and cant be good. any and all help is appreciated.
