i recently bought a boat with a 2008 yamaha 200 fourstroke. it was always a little stiff to change in and out of gear when in the water but nothing to bad to deal with. I recently changed the water pump and thermostats then drained the lower unit and refilled it. after doing this i ran it on the hose for about 20 minutes. It shifted amazing clicked rite in forward and reverse it was acting like a new boat. went to the dock and was pulling it off the trailer it clunked into reverse then wouldnt go back in neutral i almost hit another boat i slammed it forward and it thunked into gear and it was extremely stiff and almost impossible to get bback in neutral. if i turn it off and put it in neutral when i started it back up it would stay in neutral untill i moved it again. does anyone have any idea what could be the problem i thought the cable at first but with how well it ran on the hose im lost. thanks in advance
