HELP !! Have a 1996 johnson fast strike 175HP running 19 ft. stratos. On holeshot bow raising up and when trimming up the boat doesn't get on plane, the stern just seems to bog down. If I keep hotfoot down it will evenually get on plane. It just started doing this all of a sudden. Was fishing on lake... boat was running fine..stopped to hit couple spots and when I went to move on boat started doing above..You guys have any ideas ? Thanks !!!!
